     FIELD 
     The subject matter disclosed herein relates to a dispensing unit with ball functionality. More specifically, to a ball functionality that allows for enhance fluid discharge. 
     INFORMATION 
     The dispensing industry has numerous ways to dispense one or more fluids and/or gases. This disclosure highlights enhanced devices, methods, and systems for dispensing these one or more fluids and/or gases. 
     Carbonated dispensing head valves commonly incorporate a “paddle valve” having an arm that activates the “open and close” function of the valve. The arm is required to penetrate through the chamber wall into the liquid chambers. This penetration creates a major failure point (i.e. leakage, sealing issues, etc.) of the existing units on the market. Additionally, with “wet” pistons in the solenoid a disadvantage occurs with the requirement that is has to be closely machined parallel to the sliding surfaces, as accuracy of the sliding surfaces is critical to maintaining closing of the orifice. However, the lubricant for the sliding is typically the fluid that is being turned on and off. Thus, in many cases the character of the fluid can have problems serving as a lubricant. Lastly, as the piston is fixed, it is not self-cleaning. It is to overcoming these problems with current paddle valves that the below disclosed novel valve is directed to.

     DETAILED DESCRIPTION 
     Disclosed is a novel valve that does not require a shaft, piston, etc. or other component that is required to penetrated through the wall of the chamber where the liquid travels through (i.e. penetrates from outside the liquid to inside the chamber or wet side). With the below described valve, the necessity to penetrate into the wet side to actuate the “on/off” for the valve is eliminated. 
     A ball or other substantially round or spherical object (collectively “Ball”) may be used and controlled by rolling the Ball off the opening to open the valve for fluid flow there through. This mechanism of rolling the Ball off the opening is a mechanically easier process than the conventional lifting or diaphragm of the Ball in order to open the passage/orifice. 
     With the disclosed rolling Ball valve, once the Ball is even partially off the orifice/opening then the pressure will equalize on both sides of the orifice and the effort to move the Ball further off, farther to fully open, may take almost no energy at all. Once the Ball is decoupled from the magnet or the electro magnet is off—the fluid flow itself will roll [suck] the Ball back into the orifice and close the valve. The higher the input pressure the tighter the valve closes. In practice the orifice, as depicted, would be the most accommodating design for a valve seat as well (i.e. a self-cleaning rubber design) as used in the CFValves. 
       FIG.  1 A  ad  FIG.  1 B  illustrate a first embodiment for the valve in a valve closed position.  FIG.  1 A  illustrates a top sectional view, whereas  FIG.  1 B  illustrates a side sectional view for the first embodiment in the closed position. As seen in these two Figures a Ball covers/closed an orifice opening, with a portion of the Ball extending into the orifice opening. With the Ball closing the orifice opening, fluid is prevented from flowing through the pipe, tube, chamber, hose or other type if fluid conduit (all collectively referred to as “Conduit”). As seen in  FIG.  1 B  a magnetic coupling located on an external/outside of the Conduit is out of magnetic range of the metal Ball and thus is unable to control the movement or position of the Ball. The Ball is therefore forced in the shown sealing position with respect to the orifice opening by the pressure flow within the Conduit. Preferably, the Ball is constructed from a magnetic, metallic and/or rigid material and all are considered within the scope of the disclosure. 
       FIG.  2 A  ad  FIG.  2 B  illustrate a first embodiment for the valve in a valve open position.  FIG.  2 A  illustrates a top sectional view, whereas  FIG.  2 B  illustrates a side sectional view for the first embodiment in the open position. As seen in these two Figures, the magnetic coupling is moved within magnetic range of the Ball, which causes the Ball to pulled towards the externally located magnetic coupling and no longer sealing the orifice opening, thus, allowing fluid flow through the orifice opening. 
       FIG.  3 A  ad  FIG.  3 B  illustrate a second embodiment for the valve in a valve closed position.  FIG.  3 A  illustrates a top sectional view, whereas  FIG.  3 B  illustrates a side sectional view for the second embodiment in a closed position. In this embodiment, the orifice opening is preferably not centered. With the magnetic coupling out of magnetic range with the Ball, the Ball is forced to seal the orifice opening by flow pressure. As seen in  FIG.  4 A  and  FIG.  4 B  when the magnetic coupling is rotated (e.g. 90 degrees, etc.), the magnetic coupling is now within magnetic range of the Ball, and thus pulls the Ball causing the orifice opening to be open and allow fluid flow there through. 
       FIG.  5 A  ad  FIG.  5 B  illustrate a third embodiment for the valve in a valve closed position.  FIG.  5 A  illustrates a top sectional view, whereas  FIG.  5 B  illustrates a side sectional view for the third embodiment in a closed position. In this embodiment, the orifice opening can be preferably centered and an electro magnet provided which preferably remains in a fixed position with respect to the Conduit. When the electro magnet “off” (i.e. not energized), the Ball is forced to seal the orifice opening by flow pressure. As seen in  FIG.  6 A  and  FIG.  6 B  when the electro magnet is “on” (i.e. energized), the electro magnet pulls the Ball towards the electro magnet which causes the orifice opening to be open and allow fluid flow there through. 
       FIG.  7 A  and  FIG.  7 B  illustrate a fourth embodiment for the valve in a valve closed position.  FIG.  7 A  illustrates a top sectional view, whereas  FIG.  7 B  illustrates a side sectional view for the third embodiment in a closed position. In this embodiment, the orifice opening can be preferably centered (however any spot can be utilized (e.g., right, center, left, slightly off center, 1 inch off center, etc.)) and a magnetic coil provided which preferably remains in a fixed position with respect to the Conduit. When the electro magnet “off” (i.e. not energized), the Ball is forced to seal the orifice opening by flow pressure. As seen in  FIG.  8 A  and  FIG.  8 B  when the magnetic coil is “on” (i.e. energized and creates a magnetic field), the Ball is pulled towards the magnetic field which causes the orifice opening to be open and allow fluid flow there through. 
     Thus, in all embodiments, the movement of the Ball over the orifice opening and out of the orifice opening is achieved without having to penetrate the wall of the Conduit which eliminates or greatly reduces previous leakage and other sealing problems, experienced at the penetrate point and the other above-identified problems with prior valves, such as, but not limited to “paddle valves”. 
     One non-limiting application for the above-described and shown novel valve is in use with a beverage machine, such as, but not limited to, the multiple beverage dispensing machines found at restaurants where a customer takes their cup and positions the cup under one of the plurality of beverage dispensing heads and presses the cup against a lever to initiate dispensing. For this application, the magnet is moved or rotated by the a mechanical lever that is secured to, part of or otherwise in mechanical communication with the lever that the customer presses their cup against to initiate dispensing. Here, when the level is pressed by the customer, the magnet is moved or rotated such that it is in range with the Ball, thus, causing the Ball to be pulled out of and/or away from the orifice, thus allowing the desired beverage to be dispensed out of the dispensing head above the customer&#39;s cup. 
     For the embodiments where the magnet is energized (as opposed to being moved or rotated) to pull the Ball away or out of the orifice, the electrical source can be a 24 V AC, though such is not considered limiting. Here, when the customer presses their cup against the level, an electrical switch is turned “closed-on” (or “opened-off depending on how the circuit is wired), causing the energy from the electrical source to flow to the electro magnet or magnetic coil, thus, causing the electro magnet or magnetic coil to pull and/or push the Ball out of or away from the orifice. 
     As an alternative to the customer pushing their cup against a lever, certain beverage machines operate with the customer pushing a button to activate an electrical circuit. Thus, this pressing of the button can be substituted for pushing the cup against the lever in the above non-limiting examples. In either method (pushing cup against lever or pressing button), the objective is to stop or start a flow of fluid through the tube, pipe, etc. through the use of one of the above described Ball/orifice magnet embodiments. 
     Though not considered limiting, the magnet, electro magnet or magnetic coil can be attached or positioned adjacent to the Conduit by a conventional mechanical fastener, screws, bolts, etc., as well as glued, tape or other adhesive, incased in a plastic cover. Additionally, where the Conduit is plastic, a receptacle for the attachment—magnet, electro magnet or magnetic coil can be molded. 
     The disclosed embodiments are not considered limited to any particular magnetic materials, orifice opening dimensions, orifice location, Ball dimensions, Ball shape (e.g., circle, ball, square, triangle, etc.) Ball to orifice opening ratio, magnet location, electro magnet location or magnetic coil location 
     All locations, sizes, shapes, measurements, ratios, amounts, angles, component or part locations, configurations, dimensions, values, materials, orientations, etc. discussed above or shown in the drawings are merely by way of example and are not considered limiting and other locations, sizes, shapes, measurements, ratios, amounts, angles, component or part locations, configurations, dimensions, values, materials, orientations, etc. can be chosen and used and all are considered within the scope of the disclosure. 
     Dimensions of certain parts as shown in the drawings may have been modified and/or exaggerated for the purpose of clarity of illustration and are not considered limiting. 
     While the valve has been described and disclosed in certain terms and has disclosed certain embodiments or modifications, persons skilled in the art who have acquainted themselves with the disclosure, will appreciate that it is not necessarily limited by such terms, nor to the specific embodiments and modification disclosed herein. Thus, a wide variety of alternatives, suggested by the teachings herein, can be practiced without departing from the spirit of the disclosure, and rights to such alternatives are particularly reserved and considered within the scope of the disclosure. 
     In  FIG.  1 A , an illustration of a ball functionality is shown, according to one embodiment. In one example, a dispensing element  200  may include a conduit  202 , a blocking element  204 , and a dispensing element  206  (e.g., orifice). In various examples, the conduit  202  may be a hose, a pipe, and/or any other element with an external surface and an internal surface which allows for the passage of one or more fluids and/or one or more gases. In various examples, the blocking element  204  may be a ball, a block, and/or any other element that stops the passage of one or more fluids and/or one or more gases when the blocking element is in one or more positions relative to the dispensing element. In this example shown in  FIG.  1 A , the blocking element  204  is positioned over the dispensing element  206  which stops the passage of one or more fluids and/or one or more gases which can be seen in  FIG.  1 B . In the example shown in  FIG.  1 B , the blocking element  204  stops a fluid flow because the flow (e.g., line PSI) is putting pressure  208  on the blocking element  204  which creates a seal between the blocking element  204  and the dispensing element  206  (the dispensing element  206  in this example is a hole and/or the orifice opening(s)). In this example, the pressure  208  is all around the blocking element but is strongest when it is parallel with the dispensing element. A movement device  220  (e.g., a magnet) is in a first position  220 A which does not allow the movement device  220  to interact with the blocking element  204 . 
     In  FIG.  2 A , another illustration of a ball functionality is shown, according to one embodiment. In this example, the blocking element  204  has moved to a second position relative to the dispensing element  206 . In this example, the movement device  220  has moved to a second position  220 B which allows the movement device  220  to interact with the blocking element as shown in  FIG.  2 B . The movement device  220  (e.g., a magnet) has caused the blocking element  204  (e.g., a Ferro-magnetic material and/or a metal ball) to move in a first direction  210  towards the movement device  220  which allows for a first fluid flow  211  to move towards the dispensing element  206  and a second fluid flow  222  through the dispensing element  206  until the movement device is moved back to the first position  220 A which causes the blocking element to move back to a position to block the flow of fluids through the dispensing element  206  as shown in  FIG.  1 B . The movement device  220  in this example is magnetically tied to the blocking element  204 . Therefore, when the movement device  220  moves the blocking element  204  moves. It should be noted that there is a pressure difference (e.g., pressure differential) between the second area with the second fluid flow  222  and the first area with the first fluid flow  211 . 
     In  FIG.  3 A , an illustration of a ball functionality is shown, according to one embodiment. In one example, a dispensing device  300  may include a conduit  202 , a blocking element  204 , and a dispensing element  206 . In various examples, the conduit  202  may be a hose, a pipe, and/or any other element with an external surface and an internal surface which allows for the passage of one or more fluids and/or one or more gases. In various examples, the blocking element  204  may be a ball, a block, an egg shaped item, a tear drop shaped item, a golf tee shaped item, and/or any other shape. Further the blocking element  204  may be any other element that stops the passage of one or more fluids and/or one or more gases when the blocking element is in one or more positions relative to the dispensing element. In this example shown in  FIG.  3 A , the blocking element  204  is positioned over the dispensing element  206  which stops the passage of one or more fluids and/or one or more gases which can be seen in  FIG.  3 B . In the example shown in  FIG.  3 B , the blocking element  204  stops a fluid flow because the flow (e.g., line PSI) is putting pressure  208  on the blocking element  204  which creates a seal between the blocking element  204  and the dispensing element  206  (the dispensing element  206  in this example is a hole). A movement device (e.g., a magnet) is in a first position  304  which does not allow the movement device to interact with the blocking element  204 . 
     In  FIG.  4 A , another illustration of a ball functionality is shown, according to one embodiment. In this example, the blocking element  204  has moved to a second position relative to the dispensing element  206 . In this example, the movement device has moved to a second position  302  which allows the movement device to interact with the blocking element as shown in  FIG.  4 B . The movement device (e.g., a magnet) has caused the blocking element  204  (e.g., a Ferro-magnetic material and/or a metal ball) to move in a first direction  210  which allows for a first fluid flow  211  to move towards the dispensing element  206  and a second fluid flow  222  through the dispensing element  206  until the movement device is moved back to the first position  304  which causes the blocking element to move back to a position to block the flow of fluids through the dispensing element  206  as shown in  FIG.  4 B . In this example, the movement device is magnetically locked onto the blocking element  204 . Therefore, when the movement device moves the blocking element  204  moves. 
     In  FIG.  5 A , an illustration of a ball functionality is shown, according to one embodiment. In one example, a dispensing system may include the conduit  202 , the blocking element  204 , and the dispensing element  206 . In various examples, the conduit  202  may be a hose, a pipe, and/or any other element with an external surface and an internal surface which allows for the passage of one or more fluids and/or one or more gases. In various examples, the blocking element  204  may be a ball, a block, and/or any other element that stops the passage of one or more fluids and/or one or more gases when the blocking element is in one or more positions relative to the dispensing element. In this example shown in  FIG.  5 A , the blocking element  204  is positioned over the dispensing element  206  which stops the passage of one or more fluids and/or one or more gases which can be seen in  FIG.  5 B . In the example shown in  FIG.  5 B , the blocking element  204  stops a fluid flow because the flow (e.g., line PSI) is putting pressure  208  on the blocking element  204  which creates a seal between the blocking element  204  and the dispensing element  206  (the dispensing element  206  in this example is a hole or sealing ring). A movement device  500  (e.g., a magnet) is in a first state (e.g., de-energized) which does not allow the movement device  500  to interact with the blocking element  204 . 
     In  FIG.  6 A , another illustration of a ball functionality is shown, according to one embodiment. In this example, the blocking element  204  has moved to a second position relative to the dispensing element  206 . In this example, the movement device  500  has been energized and is in a second state  502  which allows the energized movement device  502  to interact with the blocking element as shown in  FIG.  6 B . The energized movement device  502  (e.g., a magnet) has caused the blocking element  204  (e.g., a Ferro-magnetic material and/or a metal ball) to move in a first direction  210  towards the energized movement device  502  which allows for a first fluid flow  211  to move towards the dispensing element  206  and a second fluid flow  222  through the dispensing element  206  until the energized movement device  502  returns in an de-energized movement device  500  which causes the blocking element to move back to a position to block the flow of fluids through the dispensing element  206  as shown in  FIG.  6 B . 
     In  FIG.  7 A , an illustration of a ball functionality is shown, according to one embodiment. In one example, a dispensing apparatus may include the conduit  202 , the blocking element  204 , and the dispensing element  206 . In various examples, the conduit  202  may be a hose, a pipe, and/or any other element with an external surface and an internal surface which allows for the passage of one or more fluids and/or one or more gases. In various examples, the blocking element  204  may be a ball, a block, and/or any other element that stops the passage of one or more fluids and/or one or more gases when the blocking element is in one or more positions relative to the dispensing element. In this example shown in  FIG.  7 A , the blocking element  204  is positioned over the dispensing element  206  which stops the passage of one or more fluids and/or one or more gases which can be seen in  FIG.  7 B . In the example shown in  FIG.  7 B , the blocking element  204  stops a fluid flow because the flow (e.g., line PSI) is putting pressure  208  on the blocking element  204  which creates a seal between the blocking element  204  and the dispensing element  206  (the dispensing element  206  in this example is a hole). A movement device  700  (e.g., a magnet) is in a first state (e.g., de-energized) which does not allow the movement device  700  to interact with the blocking element  204 . 
     In  FIG.  8 A , another illustration of a ball functionality is shown, according to one embodiment. In this example, the blocking element  204  has moved to a second position relative to the dispensing element  206 . In this example, the movement device  700  has been energized and is in a second state  702  which allows the energized movement device  702  to interact with the blocking element as shown in  FIG.  8 B . The energized movement device  702  (e.g., a magnet) has caused the blocking element  204  (e.g., a Ferro-magnetic material and/or a metal ball) to move in a first direction  704  towards the energized movement device  702  which allows for a first fluid flow  211  to move towards the dispensing element  206  and a second fluid flow  222  through the dispensing element  206  until the energized movement device  702  returns in an de-energized movement device  700  which causes the blocking element to move back to a position to block the flow of fluids through the dispensing element  206  as shown in  FIG.  8 B . 
     In  FIG.  9 A , another illustration of a ball functionality is shown, according to one embodiment. A dispensing device  902  may include an inlet area with a fluid flow  904  that comes into a first chamber. The first chamber includes a blocking device  906  and a first chamber outlet area  908 . Further, dispensing device  902  includes a dispensing device outlet area  914 . In this example, a magnet  900  is not energized which allows the blocking device  906  to be in a first position relative to the first chamber outlet area  908  which prevents the fluid flow  904  from exiting the first chamber outlet area  908 . In  FIG.  9 B , the magnet  900  is energized  910  which moves the blocking device  906  to a second position relative to the first chamber outlet area  908  and/or dispensing device outlet area  914  which allows the fluid flow  904  to exit from the first chamber outlet area  908  and creates a low pressure area  912 . 
     In one example, the blocking device  906  becomes trapped in the low pressure area  912  and/or a second low pressure area  920  as shown in  FIG.  9 C . The magnet  900  may be energized  910  to remove the blocking device from the low pressure area  912  and/or a second low pressure area  920  as shown in  FIG.  9 D . 
       FIG.  10 A  shows a dispensing apparatus  1006  with a metal ball  1008  (and/or a Ferro-magnetic material—e.g., brass), a dispensing area  1010 , and a magnetic coil  1002 . In this example, the magnetic coil  1002  is not energized which allows the metal ball  1008  to block the flow of liquids and/or gases from escaping through the dispensing area  1010 . However, once the magnetic coil  1002  is energized  1004 , the metal ball  1008  move to a second position which allows for the flow of liquids and/or gases via the dispensing area  1010 . 
       FIG.  11 A  shows a dispensing system  1104  where a plastic covered metal ball  1100  is utilized to block the flow of fluids and/or gases from a dispensing unit  1102 . In this example, once a magnet  1002  is energized, the plastic covered metal ball  1100  moves to a position that allows for the flow of fluids and/or gases from a dispensing unit  1102  as shown in  FIG.  11 B . 
     In  FIG.  12   , an illustration of a dispensing unit with one or more ball functionalities is shown, according to one embodiment. A dispensing system  1200  may include a magnet  1202  (and/or any other movement device and/or initiating device) and one or more dispensing units  1208 . In one example, when the magnet  1202  moves in a first direction  1204  one or more of the one or more dispensing units  1208  may discharge one or more fluids and/or gases. In one example, when the magnet  1202  moves in a second direction  1206  one or more of the one or more dispensing units  1208  may discharge one or more fluids and/or gases. In a first example, an orange flavored drink may be dispensed when the magnet  1202  comes into a first relative position to a first dispensing unit. In a second example, a cherry flavored drink may be dispensed when the magnet  1202  comes into a second relative position to a second dispensing unit. In a third example, a cola flavored drink may be dispensed when the magnet  1202  comes into a third relative position to a third dispensing unit. In a fourth example, a lemon flavored drink may be dispensed when the magnet  1202  comes into a fourth relative position to a fourth dispensing unit. In an Nth example, a peach flavored drink may be dispensed when the magnet  1202  comes into an Nth relative position to an Nth dispensing unit. 
     In  FIG.  13 A , another illustration of a dispensing unit with one or more ball functionalities is shown, according to one embodiment. A dispensing system may include a magnet  1300  (and/or any other movement device and/or initiating device) and one or more dispensing units (a first dispensing unit  1302 , a second dispensing unit  1304 , a third dispensing unit  1306 , a fourth dispensing unit  1308 , an Nth-1 dispensing unit  1310 , and an Nth dispensing unit  1312 . In a first example, an orange flavored drink may be dispensed when the magnet  1300  comes into a first relative position to a first dispensing unit  1302  by moving a blocking element  1314 . In a second example, a cherry flavored drink may be dispensed when the magnet  1300  comes into a second relative position to a second dispensing unit  1304  by moving a blocking element  1314 . In a third example, a cola flavored drink may be dispensed when the magnet  1300  comes into a third relative position to a third dispensing unit  1306  by moving a blocking element  1314 . In a fourth example, a lemon flavored drink may be dispensed when the magnet  1300  comes into a fourth relative position to a fourth dispensing unit  1308  by moving a blocking element  1314 . In an Nth-1 example, a black cherry flavored drink may be dispensed when the magnet  1300  comes into an Nth-1 relative position to an Nth-1 dispensing unit  1310  by moving a blocking element  1314 . In an Nth example, a peach flavored drink may be dispensed when the magnet  1300  comes into an Nth relative position to an Nth dispensing unit  1312  by moving a blocking element  1314 . 
     In  FIG.  13 B , another illustration of a dispensing unit with one or more ball functionalities is shown, according to one embodiment. In this example, a dispensing apparatus  1350  includes one or more dispensing units  1354  and a currently selected dispensing unit  1360 . The currently selected dispensing unit  1360  dispenses one or more drinks via a triggering unit  1356  with a triggering mechanism  1358 . In this example, the one or more dispensing units  1354  and/or the triggering unit  1356  and/or the triggering mechanism  1358  may move in any direction  1352 . 
     In  FIG.  14   , an illustration of a dispensing unit with one or more ball functionalities is shown, according to one embodiment. A dispensing system  1400  may include a dispensing unit  1402 . The dispensing unit  1402  may include a dispensing head  1404 , an input device  1406  with an input receiving area  1408  and magnetic area  1410 , a drink unit  1418  with a blocking element  1416 , and a feed line  1414 . Further, the input device  1406  may have a spring support  1412 . In one example, when a person wants a drink that person pushes their cup on the input receiving area  1408  which moves the input device  1406  towards the drink unit  1418 . After the input device  1406  (and the magnetic area  1410 ) come in proximate to the drink unit  1418  (and the blocking element  1416 ) flow of the fluid is initiated based on the magnetic area  1410  moving the blocking element  1416 . Once the person stops pushing the input device  1406 , the magnetic area  1410  moves away from the blocking element  1416  and the flow of fluids is stopped by the blocking element  1416 . 
       FIG.  15 A  shows a top view of a dispensing unit  1500  including an outer surface  1502 , an inner surface  1506 , one or more locations for a drink unit  1508 , and a magnetic area  1504 .  FIG.  15 B  shows a side view of the dispensing unit  1500 .  FIG.  15 C  shows another view of the dispensing unit  1500 . 
     In  FIG.  16 A , another illustration of a dispensing unit with one or more ball functionalities is shown, according to one embodiment. A dispensing system  1600  may one or more dispensing devices  1602 , a magnet  1610  (and/or any other movement device and/or initiating device) and one or more dispensing units (a first dispensing unit  1606 , a second dispensing unit  1604 , a third dispensing unit, a fourth dispensing unit, an Nth-1 dispensing unit, and an Nth dispensing unit  1608 . In a first example, an orange flavored drink may be dispensed when the magnet  1610  comes (and/or is energized) into a first relative position to a first dispensing unit  1606  by moving a blocking element which allows for a fluid flow  1612 . In a second example, a cherry flavored drink may be dispensed when the magnet  1610  comes (and/or is energized) into a second relative position to a second dispensing unit  1604  by moving a blocking element which allows for the fluid flow  1612 . In a third example, a cola flavored drink may be dispensed when the magnet  1610  comes (and/or is energized) into a third relative position to a third dispensing unit by moving a blocking element which allows for the fluid flow  1612 . In a fourth example, a lemon flavored drink may be dispensed when the magnet  1610  comes (and/or is energized) into a fourth relative position to a fourth dispensing unit by moving a blocking element which allows for the fluid flow  1612 . In an Nth example, a peach flavored drink may be dispensed when the magnet  1610  comes (and/or is energized) into an Nth relative position to an Nth dispensing unit  1608  by moving a blocking element which allows for the fluid to flow. In another example shown in  FIG.  16 B , a carbonated water unit  1614  may be utilized. 
     In  FIG.  17   , a flow diagram of a ball functionality is shown, according to one embodiment. A method  1700  may include having a check ball (e.g., blocking element, blockage device, etc.) in a blocking position to block a fluid flow based on a magnet being in a first position (step  1702 ). The method  1700  may include moving the magnet to a second position (step  1704 ). The method  1700  may include having the check ball in an unblocking positon which allows fluid flow (and/or gaseous flow) based on the magnet being in a second position (step  1706 ). 
     In one example, the blocking element  204  is positioned over the dispensing element  206  which stops the passage of one or more fluids and/or one or more gases which can be seen in  FIG.  1 B . In the example shown in  FIG.  1 B , the blocking element  204  stops a fluid flow because the flow (e.g., line PSI) is putting pressure  208  on the blocking element  204  which creates a seal between the blocking element  204  and the dispensing element  206  (the dispensing element  206  in this example is a hole). A movement device  220  (e.g., a magnet) is in a first position  220 A which does not allow the movement device  220  to interact with the blocking element  204 . 
     Further, the blocking element  204  has moved to a second position relative to the dispensing element  206 . In this example, the movement device  220  has moved to a second position  220 B which allows the movement device  220  to interact with the blocking element as shown in  FIG.  2 B . The movement device  220  (e.g., a magnet) has caused the blocking element  204  (e.g., a Ferro-magnetic material and/or a metal ball) to move in a first direction  210  towards the movement device  220  which allows for a first fluid flow  211  to move towards the dispensing element  206  and a second fluid flow  222  through the dispensing element  206  until the movement device is moved back to the first position  220 A which causes the blocking element to move back to a position to block the flow of fluids through the dispensing element  206  as shown in  FIG.  1 B . 
     In  FIG.  18   , a flow diagram of a ball functionality is shown, according to one embodiment. A method  1800  may include having a check ball (e.g., blocking element, blockage device, etc.) in a blocking position to block fluid flow based on the magnet being off (e.g., de-energized) (step  1802 ). The method  1800  may include turning the magnet on (e.g., energizing) (step  1804 ). The method  1800  may include having the check ball in an unblocking position based on the magnet being on (step  1806 ). 
     In one example, the blocking element  204  is positioned over the dispensing element  206  which stops the passage of one or more fluids and/or one or more gases which can be seen in  FIG.  5 B . In the example shown in  FIG.  5 B , the blocking element  204  stops a fluid flow because the flow (e.g., line PSI) is putting pressure  208  on the blocking element  204  which creates a seal between the blocking element  204  and the dispensing element  206  (the dispensing element  206  in this example is a hole). A movement device  500  (e.g., a magnet) is in a first state (e.g., de-energized) which does not allow the movement device  500  to interact with the blocking element  204 . 
     Further, the blocking element  204  has moved to a second position relative to the dispensing element  206 . In this example, the movement device  500  has been energized and is in a second state  502  which allows the energized movement device  502  to interact with the blocking element as shown in  FIG.  6 B . The energized movement device  502  (e.g., a magnet) has caused the blocking element  204  (e.g., a Ferro-magnetic material and/or a metal ball) to move in a first direction  210  towards the energized movement device  502  which allows for a first fluid flow  211  to move towards the dispensing element  206  and a second fluid flow  222  through the dispensing element  206  until the energized movement device  502  returns in an de-energized movement device  500  which causes the blocking element to move back to a position to block the flow of fluids through the dispensing element  206  as shown in  FIG.  6 B . 
     In another example, the blocking element  204  is positioned over the dispensing element  206  which stops the passage of one or more fluids and/or one or more gases which can be seen in  FIG.  7 B . In the example shown in  FIG.  7 B , the blocking element  204  stops a fluid flow because the flow (e.g., line PSI) is putting pressure  208  on the blocking element  204  which creates a seal between the blocking element  204  and the dispensing element  206  (the dispensing element  206  in this example is a hole). A movement device  700  (e.g., a magnet) is in a first state (e.g., de-energized) which does not allow the movement device  700  to interact with the blocking element  204 . 
     Further, the blocking element  204  has moved to a second position relative to the dispensing element  206 . In this example, the movement device  700  has been energized and is in a second state  702  which allows the energized movement device  702  to interact with the blocking element as shown in  FIG.  8 B . The energized movement device  702  (e.g., a magnet) has caused the blocking element  204  (e.g., a Ferro-magnetic material and/or a metal ball) to move in a first direction  704  towards the energized movement device  702  which allows for a first fluid flow  211  to move towards the dispensing element  206  and a second fluid flow  222  through the dispensing element  206  until the energized movement device  502  returns in an de-energized movement device  700  which causes the blocking element to move back to a position to block the flow of fluids through the dispensing element  206  as shown in  FIG.  8 B . 
     In  FIG.  19   , a flow diagram of a ball functionality is shown, according to one embodiment. A method  1900  may include having one or more check balls (e.g., blocking element, blockage device, etc.) in one or more dispensing units which have one or more flavors in a non-flow position (step  1902 ). The method  1900  may include moving an initiating flow device towards one dispensing unit (step  1904 ). The method  1900  may include initiating flow on one dispensing unit based on the initiating device moving the check ball (step  1906 ). In one example, when a person wants a drink that person pushes their cup on the input receiving area  1408  which moves the input device  1406  towards the drink unit  1418 . After the input device  1406  (and the magnetic area  1410 ) come in proximate to the drink unit  1418  (and the blocking element  1416 ) flow of the fluid is initiated based on the magnetic area  1410  moving the blocking element  1416 . Once the person stops pushing the input device  1406 , the magnetic area  1410  moves away from the blocking element  1416  and the flow of fluids is stopped by the blocking element  1416 . 
     In  FIG.  20   , a regulating valve includes an outer housing comprised of a cap joined to a base. The housing is internally subdivided by a barrier wall into a head section and a base section, the latter being further subdivided by a modulating assembly into a fluid chamber and a spring chamber. An inlet and a 90° outlet (please note outlet angle may be any angle from 0 to 360 degrees) in the cap communicate with the fluid chamber. Fluid at a variable pressure is admitted into the fluid chamber via the inlet, with the modulating assembly serving to maintain the fluid exiting the fluid chamber via the outlet at a substantially constant pressure. 
     This disclosure relates generally to fluid valves, and is concerned in particular with a regulating valve that is normally closed, that is opened by a variable fluid pressure above a selected threshold level, and that when open, serves to deliver the fluid at a constant pressure and flow rate 
     The drawing in  FIG.  20    is a sectional view through a regulating valve in accordance with the present disclosure, the valve being shown is in its open condition. 
     With reference to the drawing, a regulating valve in accordance with the present disclosure is generally depicted at  2010 . The valve includes an outer housing having a cap  2012  joined to a cup-shaped base  2014  at mating exterior flanges  2016 ,  2018 , with an O-ring seal  2020  interposed there between. 
     The housing is internally subdivided by a barrier wall  2022  into a head section  2024  and a base section  2026 . An inlet  2028  in the cap  2012  is adapted to be connected to a fluid supply (not shown) having a pressure that can vary from below to above a threshold level. The inlet  2028  and a central port  2030  in the barrier wall  2022  are aligned along a central axis A 1  of the valve. An outlet port  2031 , also in the cap  2012 , is aligned on a second axis A 2  transverse to the first axis A 1 . 
     A modulating assembly  2032  cooperates with the barrier wall  2022  to subdivide the base section into a fluid chamber  2031  segregated from a spring chamber  2023 ″. The modulating assembly serves to prevent fluid flow through the valve when the fluid pressure at the inlet  2028  is below the threshold pressure. 
     When the fluid pressure at the inlet exceeds the threshold pressure, the modulating assembly serves to accommodate fluid flow from the head section  2024  through port  2030  into chamber  2023 ′ at a constant pressure and flow rate, and from there through outlet port  2031 . Either the outlet port  2031  or a downstream orifice or flow restrictor (not shown) serves to develop a back pressure in fluid chamber  2023 ′. 
     The modulating assembly  2032  includes a piston comprised of a hollow shell  2034  and a central plug  2036 . The piston is supported for movement in opposite directions along axis A 1  by a flexible annular diaphragm  2038 . The inner periphery of the diaphragm is captured between the shell  2034  and plug  2036 . The cup shaped base  2014  has a cylindrical wall segment  2014 ′ received within the cap  2012 . The outer periphery of the diaphragm is captured between an upper rim  2015  of the wall segment  2014 ′ and an inwardly projecting interior ledge  2017  on the cap. 
     A stem  2040  on the piston plug  2036  projects through the port  2030  into the head section  2024 . An enlarged head  2042  on the stem has a tapered underside  2044  that coacts with a tapered surface  2046  of the barrier wall to modulate the size of the flow path through the port  2030  as an inverse function of the varying fluid pressure in the input section, with the result being to deliver fluid to the outlet  2031  at a constant pressure and flow rate. 
     A compression spring  2048  in the spring chamber  2023 ″ is captured between an underside surface of shell  2034  and the bottom wall  2052  of the housing base  2014 . The spring urges the modulating assembly  2032  towards the barrier wall  2022 . When the fluid pressure at the inlet  2028  is below the threshold pressure, spring  2048  serves to urge the diaphragm  2038  against the barrier wall  2022 , thus preventing fluid flow from the fluid chamber  2023 ′ to the outlet  2031 ′. As the fluid pressure exceeds the threshold pressure, the resilient closure force of spring  2048  is overcome, allowing the piston assembly to move away from the barrier wall, and allowing the modulating function of the coacting tapered surfaces  2044 ,  2046  to commence. An opening  2050  in the bottom wall  2052  serves to vent the volume beneath diaphragm  2038  to the surrounding atmosphere. 
     In one example, a regulating valve for receiving fluid at a variable pressure from a fluid source and for delivering the fluid at a substantially constant pressure and flow rate to a fluid applicator or the like, the valve including: a cup-shaped base having a cylindrical wall segment terminating in an upper rim, and an externally projecting first flange; a cap having an inwardly projecting ledge and an externally projecting second flange, the cup-shaped base and the cap being configured and dimensioned for assembly as a unitary housing, with the cylindrical wall segment of the cup-shaped base inserted into the cap, and with the extent of such insertion being limited by the abutment of the first flange with the second flange to thereby provide a space between the upper rim of the cup-shaped base and the inwardly projecting ledge of the cap; a barrier wall subdividing the interior of the housing into a head section and a base section; a modulating assembly subdividing the base section into a fluid chamber and a spring chamber; an inlet in the cap for connecting the head section to the fluid source; a port in the barrier wall connecting the head section to the fluid chamber, the port being aligned with a central first axis of the valve; an outlet in the cap communicating with the fluid chamber, the outlet being aligned on a second axis transverse to the first axis; a stem projecting from the modulating assembly along the first axis through the port into the head section; a flexible diaphragm supporting the modulating assembly within the housing for movement in opposite directions along the first axis, the diaphragm having an outer periphery captured in the space between the inwardly projecting ledge of the cap and a rim of the cylindrical wall segment of the cup-shaped base; a spring in the spring chamber, the spring being arranged to resiliently urge the modulating assembly into a closed position at which the diaphragm is in sealing contact with the barrier wall to thereby prevent fluid flow from the head section via the port and fluid chamber to the outlet, the spring acting in concert with the modulating assembly and the stem projecting therefrom to modulate the size of the port as an inverse function of the variable fluid pressure in the input sections whereby the pressure and flow rate of the fluid delivered to the outlet is maintained substantially constant, the valve being automatically actuated when the pressure of the fluid acting on the modulating assembly exceeds a threshold level, and being automatically closed when the pressure drops below the threshold level. 
     In  FIG.  21   , a magnetically activated ball valve device  2100  has been added to regulating valve  2010  where the magnetically activated ball valve device  2100  is located in a position relative to the inlet (e.g., incoming fluid). In this example, the magnetically activated ball valve device  2100  includes an opening  2106 , a ball  2102 , and a magnetic device  2104 . Additional embodiments of the magnetically activated ball valve device  2100  and the functionality of the magnetically activated ball valve device  2100  are shown in other figures of this disclosure. In other embodiments, the ball valve device  2100  may be activated by the fluid flow, mechanical functionality (e.g., levers, etc.), magnetic functionality, and/or any combination of movement devices. 
     In  FIG.  22   , a magnetically activated ball valve device  2202  has been added to regulating valve  2028  where the magnetically activated ball valve device  2202  is located in a position relative to the outlet (e.g., outgoing fluid). In this example, the magnetically activated ball valve device  2202  includes an opening  2200 , a ball  2204 , and a magnetic device  2206 . Additional embodiments of the magnetically activated ball valve device  2202  and the functionality of the magnetically activated ball valve device  2202  are shown in the other figures of this disclosure. 
     A constant flow regulating valve includes a closure mechanism configured and arranged to override the modulating mode of the valve and to close the valve at fluid inlet pressures both below and above the valve&#39;s threshold level. The closure mechanism may be selectively deactivated to thereby allow the valve to assume its normal pressure responsive regulating functions. Embodiments of the regulating valve incorporate pressure relief devices and vent seals, with configurations suitable for incorporation into the trigger assemblies of portable sprayers. 
     This disclosure relates generally to fluid valves, and is concerned in particular with a regulating valve that operates in response to a variable fluid inlet pressure above a selected threshold level to deliver the fluid at a constant outlet pressure and flow rate. A closure mechanism is selectively operable either to accommodate the valve&#39;s normal pressure responsive regulating functions, or to override such functions by maintaining the valve in a closed state at inlet pressures both above and below the threshold level. 
     In one example, valves are normally closed in response to fluid inlet pressures below a threshold level, and operate in a modulating mode in response to variable fluid inlet pressures above the threshold level to deliver fluids at constant outlet pressures and flow rates. However, at fluid inlet pressures above the threshold level, such valves remain open and cannot serve as shut off valves, thus making it necessary to employ additional and separately operable valves to achieve this added function. 
     In accordance with one aspect of the present disclosure, the known regulating valves are modified to include closure mechanisms configured and arranged to override the modulating mode of the valves and to maintain closure of the valves at fluid inlet pressures both below and above the threshold level. The closure mechanisms may be selectively deactivated to thereby allow the valves to assume their normal pressure responsive regulating functions. 
     In accordance with still another aspect of the present disclosure, the vent opening communicating with the valve&#39;s spring chamber is provided with a seal which allows air to escape and enter the spring chamber, but which prevents the escape of liquid from the spring chamber in the event that the valve diaphragm is breached. 
     In accordance with another aspect of the present disclosure, a pressure relief mechanism is provided for relieving residual fluid inlet pressure below the threshold level when the valve is closed. 
     In accordance with another aspect of the present disclosure, multiple valve components are preassembled into integral subassemblies that are configured and arranged for final assembly into an outer housing structure. 
     In accordance with a further aspect of the present disclosure, the valve is integrated into the trigger assembly of a portable sprayer. 
     With reference initially to  FIG.  23   , a regulating valve in accordance with the present disclosure is generally depicted at  2010 . The valve includes an outer housing having a cap  2012  joined to a cup-shaped base  2014  at mating exterior flanges  2016 ,  2018 . 
     The housing is internally subdivided by a barrier wall  2022  into a head section  2024  and a base section  2026 . An inlet  2028  in the cap  2012  is adapted to be connected to a fluid supply (not shown) having a pressure that can vary from below to above a threshold level. The inlet  2028  and a central port  2030  in the barrier wall  2022  are preferably aligned coaxially with a central axis A 1  of the valve. An outlet port  2031  is provided in the cap  2012 , and may be aligned on a second axis A 2  transverse to the first axis A 1 . Although the axis A 2  is shown at 90° with respect to axis A 1 , it will be understood that axis A 2  may be oriented at other angles with respect to axis A 1  in order to suit various applications of the valve. 
     A modulating assembly  2032  internally subdivides the base section into a fluid chamber  2023 ′ segregated from a spring chamber  2023 ″. The modulating assembly serves to prevent fluid flow through the valve when the fluid pressure at the inlet  2028  is below the threshold pressure. When the fluid pressure at the inlet exceeds the threshold pressure, the modulating assembly serves to accommodate fluid flow from the head section  2024  through port  2030  into fluid chamber  2023 ′ and from there through outlet port  2031  at a substantially constant outlet pressure and flow rate. Either the outlet port  2031  or a downstream orifice or flow restrictor (not shown) serves to develop a back pressure in fluid chamber  2023 ′. 
     The modulating assembly  2032  includes a piston comprised of a hollow shell  2034  and a central plug  2036 . The piston is supported for movement in opposite directions along axis A 1  by a flexible annular diaphragm  2038 . The inner periphery of the diaphragm is captured between the shell  2034  and plug  2036 . The cup shaped base  2014  has a cylindrical wall segment  2014 ′ received within the cap  2012 . The outer periphery of the diaphragm is captured between an upper rim  2015  of the wall segment  2014 ′ and an inwardly projecting interior ledge  2017  on the cap. The outer periphery of the diaphragm thus serves as an effective seal between the cap  2012  and base  2014 . 
     A stem  2040  on the piston plug  2036  projects through the port  2030  into the head section  2024 . An enlarged head  2042  on the stem has a tapered underside  2044  that coacts with a tapered surface  2046  of the barrier wall to modulate the size of the flow path through the port  2030  as an inverse function of the varying fluid pressure in the input section, with the result being to deliver fluid to the outlet  2031  at a substantially constant pressure and flow rate. 
     A compression spring  2048  in the spring chamber  2023 ″ is captured between an underside surface of shell  2034  and the bottom wall  2052  of the housing base  2014 . The spring urges the modulating assembly  2032  towards the barrier wall  2022 . When the fluid inlet pressure is below the threshold pressure, spring  2048  serves to urge the diaphragm  2038  against a sealing ring  2049  on the underside of the barrier wall  2022 , thus preventing fluid through flow from the head section  2024  via port  2030  and fluid chamber  2023 ′ to the outlet  2031 . As the fluid inlet pressure exceeds the threshold pressure, the resilient closure force of spring  2048  is overcome, allowing the modulating assembly to move away from the sealing ring  2049 , and allowing the modulating function of the coacting tapered surfaces  2044 ,  2046  to commence. An opening  2050  in the bottom wall  2052  serves to vent the volume beneath diaphragm  2038  to the surrounding atmosphere. 
     An operating means includes a solenoid  2054  fitted to the underside of the cup-shaped base  2014 . The solenoid includes a magnet  2056  surrounding a magnet core  2058 . A rod  2060  projects from the magnet core along axis A 1  into the spring chamber  2023 ″ where it terminates in a flat head  2062 . A closure means includes a second compression spring  2064  surrounding the rod  2060  and captured between the head  2062  and an annular interior boss  2066  on the bottom wall  2052  of the base  2014 . The closure force of spring  2064  exceeds that of spring  2048 . 
     In the condition shown in the drawing, the magnet  2056  has been energized to axially withdraw the core  2058 , thus pulling the head  2062  downwardly against the compressive force of spring  2064  and away from the underside of plug  2034 . This allows the modulating assembly  2032  to perform its normal pressure regulating functions as described above. 
     If the magnet  2056  is de-energized, the spring  2064  will serve to push the head  2062  up against the bottom of plug  2034  with a closure force sufficient to override the valve&#39;s normal regulating functions, resulting in the diaphragm assembly  2032  being elevated to press the diaphragm  2038  against the circular downwardly projecting sealing ring  2049  on the barrier wall  2022 . This in turn prevents fluid through flow from head section  2024  via port  2030  and fluid chamber  2023 ′ to the outlet port  2031 . A circular ledge  2070  serves as a stop to limit upward movement of the core  2058 , thus safeguarding the diaphragm  2038  from being pressed too tightly against the sealing ring  2049 . The closure force of spring  2064  is sufficient to hold the diaphragm  2038  against the sealing ring  2049  at inlet pressures above the threshold pressure. 
     In the alternative embodiment shown in  FIG.  24   , the rod  2060 ′ projects through the bottom wall  2052  to terminate in a foot  2063  acted upon by a lever  2068  mounted for pivotal movement about a pin  2069  or the like. Moving the lever up causes the rod  2060 ′ to be pulled downwardly. 
     In light of the foregoing, it will be seen that the valve  2010  can serve as a shut off valve by simply allowing the spring  2064  to override spring  2048  and maintain the diaphragm  2038  of the modulating assembly  2032  in sealing contact with the ring  2049  on barrier wall  2022 . By deactivating the closure force of spring  2064 , either by energizing the solenoid  2054  of  FIG.  23    or manually operating lever  2068  of  FIG.  24   , the valve is conditioned to assume its normal pressure responsive regulating function at inlet pressures above the threshold level. 
     As can be best seen by additional reference to  FIGS.  25  and  26   , a gas permeable hydrophobic seal  72  overlies the vent opening  50 . The seal may comprise an expanded polytetraflouroethelene (ePTFE) film, or any other gas permeable hydrophobic membrane that allows air to escape from and reenter the spring chamber  23 ″, but that in event of failure of the diaphragm  38  and entry of liquid into the spring chamber, will prevent liquid from leaking to the exterior of the valve via the vent opening  50 . The seal  72  may be adhered or heat sealed to the bottom wall  52  as at  74 . Although not shown, the seal may be reinforced, if necessary, by an additional porous membrane, e.g., a woven fabric or the like. 
       FIG.  27    depicts an alternative embodiment of the vent seal in which a bushing  76  has been snap fitted into the vent opening  50 . The bushing is molded of a hydrophilic polymer that absorbs water and swells, resulting in closure of the restricted central vent passageway  78 . This again serves to prevent leakage in the event of failure of the diaphragm  38 . 
       FIG.  28    depicts still another alternative embodiment of the vent seal in which the vent opening  50  is located at the center of bottom wall  52 . A flexible sealing diaphragm  80  of some material that is impervious to both liquids and air is adhered or heat sealed as at  82  over the vent opening. As air pressure in the spring chamber  23 ″ varies in response to flexure of the main diaphragm  38 , the sealing diaphragm  80  will respond flexibly, while at all times maintaining a sealing relationship which will prevent liquid from escaping through the vent opening. 
     It thus will be seen that the seals  72 ,  76  and  80  serve as safeguards against leakage of liquid from the regulating valve through vent opening so in the event that the diaphragm  38  is breached. 
     The regulating valves of the present disclosure are adaptable to widespread usage, a non-limiting example being to stabilize the pressure and flow of the liquid sprays emitted by portable sprayers. 
     Portable sprayers include both knapsack sprayers and compression sprayers. In the conventional knapsack sprayer, a lever actuated pump is manually operated to withdraw liquid from a non-pressurized portable tank and to deliver the liquid through a wand to a nozzle from which the liquid is expelled in a spray pattern. In a compression sprayer, the tank is pressurized to achieve the same result. In both cases, the delivery pressure varies over a wide range, which affects the liquid spray pattern. Too little pressure produces excessively large wasteful spray droplets, whereas excessive pressure operates in the reverse manner to produce an overly atomized spray which can easily drift from the intended target. 
     Some attempt at control is provided by manually operating trigger assemblies interposed in the flow path between the tank and nozzle. However, experience has proven that operators are unable to operate such trigger assemblies in a manner which reliably produces substantially uniform delivery pressures and liquid flow rates to the spray nozzles. Thus, spray patterns remain erratic; resulting in wasteful excessive liquid application and/or inadequate overly atomized sprays which often drift dangerously from their intended targets. 
     In order to address these problems, and with reference to  FIGS.  30 - 32   , a knapsack sprayer  84  includes a tank  86  adapted to contain a liquid, typically a pesticide, herbicide or the like. A pump  88  is mounted within the tank, with an inlet submerged in the liquid, and an outlet connected to a flexible hose  90  leading to trigger assembly  94  incorporating a selectively actuated regulating valve in accordance with the present disclosure. The trigger assembly  94  is in turn connected to a wand  92  having a nozzle  95  at its distal end. The pump  88  is operated by a pivotal lever  96  which is manually manipulated by an operator to withdraw liquid from the tank  86  and to deliver the liquid at a variable pressure via the hose  90  to the trigger assembly  94 . Although not shown, it will be understood that the pressurized tank of a compression sprayer would operate in a similar manner to deliver fluid at a variable pressure. 
     The trigger assembly  94  incorporates a regulating valve similar to that illustrated in  FIG.  24   , with minor modifications to accommodate its positioning in the liquid flow path between the hose  90  and wand  92 . For example, the head section  24  has been reconfigured with a 90° turn to position the inlet  28  for connection to the hose  90 , the shape and pivotal connection of the operating lever  68  has been appropriately modified to serve as the trigger, and the outlet port has been connected to the wand  92 . 
     The regulating valve of the trigger assembly  94  is held closed by the force of spring  64 . The closure force of spring  64  is relieved by depressing the trigger  68 , and in response to pump pressures above the preset threshold level, the valve operates as described previously to maintain a substantially constant delivery pressure and flow rate via the wand  92  to the nozzle  95 . By maintaining a substantially constant pressure and flow rate to the nozzle  95 , the selected spray pattern remains stable irrespective of variations in the pressure and flow rate of the liquid exiting tank  86 . 
     The regulating valve of the trigger assembly  94  may be additionally modified to include pressure relief means for relieving residual internal pressures in the head section  24  when the valve is closed and either disassembly is required for cleaning and maintenance, or when the trigger assembly is disconnected from the hose  90 . To this end, a sleeve  98  is inserted in the cap  12 . The sleeve provides a vent path  100  extending from an entry opening communicating with the head section  24  to a side exit opening  102  communicating with the fluid chamber  23 ′. A pin  104  extends through the sleeve and terminates at opposite ends in enlarged shaped closure and operating heads  106 ,  108  located respectively in head section  24  and at the valve exterior. A spring  110  serves to bias the pin to the right as viewed in the drawings, thus pulling the closure head  106  in the same direction to close off the vent path  100 , as shown in  FIG.  31   . The vent path is opened by depressing operating head  108  to shift pin in the opposite direction, as shown in  FIG.  32   , thus opening the vent path and allowing pressurized liquid in the head section  24  to be bled through opening  102  to the fluid chamber  23 ′ from which it can exit through outlet port  31  to the wand  92 . 
     With reference additionally to  FIGS.  32 - 34   , another embodiment of a regulating valve is accordance with the present disclosure is depicted at  94   a . The components of valve  94   a  that are the same or equivalent to those of value  94  depicted in  FIG.  30    have been identified with the same reference numerals with “a” as an added identify. 
     In this embodiment, the cap  12   a  serves as an outer housing structure. The cap  12   a  has a bottom opening  112  and an internal circular land  114  grooved to accept an O-ring seal  118 . The bottom opening  112  and circular land  114  are aligned on a central axis A 1 . The barrier wall  22   a  is separate from the cap  12   a  and has a circular rim  120  adapted to be seated in sealing engagement against the O-ring seal  118 . 
     The modulating assembly  32   a  again includes a piston comprised of a hollow shell  34   a  and a central plug  36   a . The piston is supported for movement along axis A 1 , by a flexible diaphragm  38   a . The inner periphery of the diaphragm is captured between the shell  34   a  and plug  36   a , and the outer periphery of the diaphragm has a beaded edge captured in an internal groove in a cylindrical skirt  122  having a circular bottom edge  124 . 
     A preassembled first subassembly  126  includes the shell  34   a , central plug  36   a , diaphragm  38   a , skirt  122 , barrier wall  22   a  and the stem  40   a.    
     A preassembled second subassembly  128  includes the cup-shaped base  14   a , compression springs  48   a  and  64   a , and the operating rod  60   a.    
     The valve  94  is an assembled by first seating the O-ring seal  118  in the groove  116  of the interior land  114 . The first subassembly  126  is then inserted through bottom opening  112  of the cap to seat its rim  120  against the O-ring seal  118 . 
     A compressible annular seal  130  is then inserted via opening  112  and located against the bottom of the diaphragm  38   a.    
     The second subassembly  128  is then inserted through bottom opening  112 . As shown in  FIG.  31   , the interior wall of the cap  12  is provided with oppositely disposed vertical grooves  132  leading to horizontal grooves  134 . The grooves  134  have ramped bottoms  136  leading to notches  138 . The cup-shaped base  14  has an oppositely disposed radially projecting ears  140 . 
     As the second subassembly  128  is inserted, the ears  140  of the cup-shaped base  14  an enter the vertical slots  132  ( FIG.  35 A ). When an internal ledge  141  adjacent to the upper rim of the cup-shaped base  14   a  initially contacts the seal  130 , the ears  140  are positioned as shown in  FIG.  35 B . The cup-shaped base is then rotated to shift the ears up the ramped bottoms  136  and into snapped engagement in the notches  136 , as shown in  FIG.  35 C . The second subassembly is then securely locked in place, with the seal  130  compressed between the underside of the diaphragm  38   a  and the ledge  141 . 
     The trigger  68  may then be operatively connected to the cap  12   a  and rod  60   a ′ to complete the assembly. 
     It will be understood that the second subassembly  128  may be secured in place by other means, including for example solvent welding or a threaded connection. Preassembly of the first and second subassemblies advantageously simplifies final assembly of the regulating valves. 
     In one embodiment, a regulating valve for receiving fluid at a variable inlet pressure from a fluid source and for delivering the fluid at a substantially constant outlet pressure and flow rate to a fluid applicator or the like, the valve may include: a housing internally subdivided by a barrier wall into a head section and a base section; a port in the barrier wall; a modulating assembly internally subdividing the base section into a fluid chamber and a spring chamber, the modulating assembly having a stem projecting along an axis through the port into the head section, and having a flexible diaphragm supporting the modulating assembly for movement in opposite directions along the axis; an inlet in the housing for connecting the head section to the fluid source; an outlet in the housing communicating with the fluid chamber; a spring in the spring chamber, the spring being responsive to inlet pressures below a threshold level to maintain the modulating assembly against the barrier wall and to thereby prevent fluid through flow from the head section via the port and fluid chamber to the outlet, the spring being yieldably responsive to inlet pressures above the threshold level to thereby accommodate movement of the modulating assembly away from the barrier wall, with an accompanying fluid through flow from the head section via the port and the fluid chamber to the outlet, and with the stem serving to modulate the size of the flow path through the port as an inverse function of variations in the inlet pressure above the threshold level, whereby the outlet pressure and flow rate is maintained at a substantially constant level; closure means acting independently of the spring, the closure means comprising a rod axially movable between a holding position in contact with and maintaining the modulating assembly against the barrier wall when the inlet pressure is both above and below the threshold level, and a deactivated position spaced from the modulating assembly; and operating means for selectively deactivating the closure means. 
     In another embodiment of the regulating valve, the rod may be aligned with and axially movable along the axis.

In another embodiment of the regulating valve, the pressure relief means comprises a vent path extending from an entry opening communicating with the head section to an exit opening communicating with the fluid chamber, a pin having a closure head in the head section and an operating head located externally of the housing, and a spring for biasing the pin into a closed position at which the closure head closes the entry opening and prevents the passage of liquid from the head section via the vent path to the fluid chamber, the operating head being depressible to overcome the biasing force of the spring to thereby permit liquid to flow from the head section via the vent path to the fluid chamber. In another embodiment of the regulating valve, the housing comprises a cap and a cup-shaped base, the barrier wall and the modulating assembly being preassembled to form a first subassembly received in the cap, and the cup-shaped base and the spring and closure means being preassembled to form a second subassembly received in and operatively coupled to the cap. In another embodiment of the regulating valve, the second subassembly is operatively coupled by snap engagement of the cup-shaped base with the cap. In another embodiment of the regulating valve, the snap engagement results from rotation of the cup-shaped base relative to the cap. In another embodiment of the regulating valve, the regulating valve includes a vent opening in the housing in communication with the spring chamber. In another embodiment of the regulating valve, the regulating valve includes a seal for the vent opening, the seal being adapted to accommodate passage of gas through the vent opening and to prevent the passage of liquid through the vent opening. In another embodiment of the regulating valve, the seal comprises a gas permeable hydrophobic membrane. In another embodiment of the regulating valve, the seal comprises a hydrophobic bushing inserted in the vent opening, the bushing defining a restricted vent passageway that is closed in response to the absorption of liquid by the bushing. In another embodiment of the regulating valve, the seal comprises a flexible diaphragm imperious to both liquids and gases. In another embodiment, a regulating valve for receiving fluid at a variable inlet pressure from a fluid source and for delivering the fluid at a substantially constant outlet pressure and flow rate to a fluid applicator or the like, the valve includes: a housing internally subdivided by a barrier wall into a head section and a base section; a port in the barrier wall; a modulating assembly internally subdividing the base section into a fluid chamber and a spring chamber, the modulating assembly having a stem projecting along an axis through the port into the head section, and having a flexible diaphragm supporting the modulating assembly for movement in opposite directions along the axis; an inlet in the housing for connecting the head section to the fluid source; an outlet in the housing communicating with the fluid chamber; a spring in the spring chamber, the spring being responsive to inlet pressures below a threshold level to maintain the modulating assembly against the barrier wall and to thereby prevent fluid through flow from the head section via the port and fluid chamber to the outlet, the spring being yieldably responsive to inlet pressures above the threshold level to thereby accommodate movement of the modulating assembly away from the barrier wall, with an accompanying fluid through flow from the head section via the port and the fluid chamber to the outlet, and with the stem serving to modulate the size of the flow path through the port as an inverse function of variations in the inlet pressure above the threshold level, whereby the outlet pressure and flow rate is maintained at a substantially constant level, and wherein the housing comprises a cap and a cup-shaped base, the barrier wall and the modulating assembly comprises a first preassembled subassembly adapted to be received in the cap, and the cup-shaped base and the spring comprise a second preassembled subassembly adapted to be received in and operatively coupled to the cap.

     In  FIG.  36   , a valve  3600  in a closed position is shown. The valve  3600  may include a sealing ring  3602 , a magnet element  3608 , a latching solenoid  3610 , and a diaphragm  3606 . The latching solenoid  3610  pushes the diaphragm  3606  against the CF valve&#39;s sealing ring blocking a flow of fluid  3604 . The latching solenoid  3610  may be either permanent magnet or residual magnetism types and with or without a spring assist  3614  for the solenoid plunger  3612 . In  FIG.  37   , a valve  3600  in an open position is shown. In the examples shown in  FIGS.  37  and  38   , a magnetic element  3608  is utilized to open and close the valve. The solenoid coil energized retracts the plunger  3612  allowing the input pressure to open the CF valve and allow modulation diaphragm to control fluid pressure and flow. In  FIG.  38    the CF valve is in a closed position. A second latching solenoid  3802  is latched and mechanically blocking the movement of the plunger  3800  in the latching solenoid  3610 . The plunger  3800  is position against the diaphragm which is forced against the sealing ring blocking fluid flow. To operate the CF valve, the second latching solenoid  3802  is activated to retract its plunger  3804  which free the plunger  3800  of the latching solenoid  3610 . Then, incoming fluid opens the CF valve and pushes the plunger  3800  back and the diaphragm is free to modulate. To close the CF valve, the latching solenoid is activated and then the second latching solenoid  3802  is activated and re-latched (after a momentary delay) which locks the diaphragm in the closed position. The mechanical locking device may be configured to several different forms using rods, levers for mechanical advantages. In  FIG.  39   , a valve  3600  in a closed position is shown. In this example, there is a first solenoid (e.g., solenoid A) and a second solenoid (e.g., solenoid B). In this example, the second solenoid is at a 90 degree angle to the first solenoid which allows the second solenoid to act as a stopper to the movement of the first solenoid. The second solenoid may be locked into the position shown in  FIG.  38    which impedes the movement of the first solenoid but does not require any energy to remain in place. Further, the second solenoid may be at any angle to the first solenoid. In addition, any stopping functionality may be utilized, such as, mechanical, magnetic, etc. In  FIG.  39   , a valve in an open position is shown. Please note that the second solenoid has moved to allow the first solenoid to move. 
     In  FIG.  40 A , a solenoid in an open position and valve in a closed position are shown. In  FIG.  40 B , a solenoid in a closed position and valve in a closed position are shown. In  FIG.  40 C , a solenoid in an open position and valve in an open position are shown. In  FIG.  40 D , a solenoid in an open position and valve in an open position but closing are shown. In various examples, the movement functionality may be performed magnetically, mechanically, pneumatically, manually, and/or any combination thereof. 
     In one example, the dispensing device is a magnetically controlled valve using an internally disposed ball and an external magnetic source.

The dispenser interface  4118  may communicate with one or more dispensing units.

The inlet fluid stream  4208  may provide a first pressure and originate from any source (e.g., utility, condition source, etc.). The inlet fluid stream  4208  may pass the throttle pin  4214  of the valve  4202 . In addition, the throttle pin  4214  and/or the diaphragm assembly  4212  may be part of the valve  4202 . Further, the valve  4202  may be a CF Valve as previously disclosed in this document. The outlet fluid stream  4210  from the valve  4202  may be at a second pressure and/or fluid flow.

     In  FIG.  42 C , another illustration of a valve and solenoid combination is shown, according to one embodiment. A third valve and solenoid combination  4200  includes the valve  4202  and the solenoid  4204 . The inlet fluid stream  4208  may provide a first pressure and originate from any source (e.g., utility, condition source, etc.). The inlet fluid stream  4208  may pass the throttle pin  4214  of the valve  4202 . In addition, the throttle pin  4214  and/or the diaphragm assembly  4212  may be part of the valve  4202 . Further, the valve  4202  may be a CF Valve as previously disclosed in this document. The outlet fluid stream  4210  from the valve  4202  may be at a second pressure and/or fluid flow.

A fourth valve and solenoid combination  4200  includes the valve  4202  and a second solenoid  4204 A. The inlet fluid stream  4208  may provide a first pressure and originate from any source (e.g., utility, condition source, etc.). The inlet fluid stream  4208  may pass the second solenoid  4204 A and the throttle pin  4214  of the valve  4202 . In this example, the second solenoid  4204 A is larger than the solenoid  4204  because the inlet fluid stream  4208  is at a first pressure which is higher than a second pressure of the outlet fluid stream  4210 . This is because the second solenoid  4204 A has been placed before the valve  4202 . The valve  4202  would have reduced the pressure from a first pressure to a second pressure to decrease the size requirements of the solenoid (e.g., solenoid  4204 ). However, since the pressure was not reduced the solenoid must be bigger to handle the increased pressure (therefore the second solenoid  4204 A is bigger than the solenoid  4204 ). In addition, the throttle pin  4214  and/or the diaphragm assembly  4212  may be part of the valve  4202 . Further, the valve  4202  may be a CF Valve as previously disclosed in this document.

In addition, the second pressure and/or fluid flow may be a predetermined pressure and/or fluid flow based on the valve  4202  configuration. Further, the second pressure and/or flow fluid may be less than the first pressure of the inlet fluid stream  4208 . In another example, the second pressure and/or flow fluid may be greater than the first pressure of the inlet fluid stream  4208 . In this example, the outlet fluid stream  4210  moves in two directions.

Further, the second pressure and/or fluid flow may be a predetermined pressure and/or fluid flow. In addition, the second pressure and/or fluid flow may be a predetermined pressure and/or fluid flow based on the valve  4202  configuration. Further, the second pressure and/or flow fluid may be less than the first pressure of the inlet fluid stream  4208 . 
     In  FIG.  44   , an illustration of a valve and solenoid combination is shown, according to one embodiment. A fifth valve and solenoid combination  4400  includes a body  4402  (e.g., CFiV body), a fluid passageway  4408 , a valve  4404 , an outlet stream area  4410 , and a solenoid  4406 .
