Trigger activated vented valve system

A valve having a valve trigger which operates to provide coincident fluidic coupling of a fluid delivery passage and fluid compensation passage to a fluid source.

A valve having a valve trigger which operates to provide coincident fluidic coupling of a fluid delivery passage and fluid compensation passage to a fluid source.

Conventional valves typically operate between an open condition and a closed condition to regulate the flow of a fluid (whether a gas or a liquid) in a conduit. The fluid can be delivered from a fluid source. When the fluid source is configured to contain the fluid in an enclosed space without a vent to atmosphere, delivery of the fluid from the enclosed space can reduce pressure in the enclosed space of the fluid source to create a partial vacuum which can make delivery of the fluid from the fluid source increasingly difficult with increase in reduction of pressure.

The conventional solution to the problem is to provide a fluid source vent discrete from outlet of the fluid source. As fluid is delivered from the fluid source, an amount of fluid (typically atmosphere) enters the fluid source through the discrete fluid source vent to establish pressure within the fluid source at about atmospheric pressure obviating a reduction in pressure or creation of a partial vacuum in the fluid source. One non-limiting example is a conventional gas container which has a spout through which gas is delivered from the gas container. A discrete vent coupled to the gas container allows atmosphere to enter the gas container to avoid a partial vacuum or a reduction in pressure which obviates or reduces pulsation in the delivery of an amount of gas from the gas container.

The problems with a discrete vent are well known. First, the vent provides a second perforation of the container from which fluid can flow when the container is inverted whether to deliver the remaining amount of fluid in the container or inadvertently inverted or tipped over. Second, the vent often allows escape of gases from the fluid source even when the vent is considered shut. Third the vent is an additional part of the container which can become clogged, defective, malfunction, or become broken.

The inventive valve and method of using the inventive valve provides a solution to obviate the reduction of pressure or the creation of a partial vacuum as fluid is delivered from the enclosed space of a fluid source.

IV. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

A valve which operates to provide coincident fluidic coupling of a fluid delivery passage and fluid compensation passage to a fluid source.

Now referring primarily toFIG. 1, a method of using an embodiment of the inventive valve (1) can include the step of providing an amount of fluid (2) located in a fluid source (3). The term “fluid source (3)” for the purpose of this invention means a vessel configured to couple to the inventive valve (1), or to which the inventive valve (1) can be configured to couple, or which can be adapted to couple to the inventive valve (1), to provide an enclosed space (4) in which an amount of fluid (2) can be located. The term “an amount of fluid” for the purposes of this invention means an amount of gas, whether a mixture of gases such as air, or other mixture of partial pressures of gases, or an amount of a single gas or substantially a single gas such as nitrogen, oxygen, argon, or the like, or an amount of liquid such as an amount of water, an amount of a solution which provides an amount of solute in an amount of solvent, an amount of fuel such as gasoline, diesel fuel, bio-diesel, or the like, an amount of alcohol such as methanol, ethanol, or isopropanol, or the like, and can further encompass an amount of liquid which entrains an amount of biological particles whether or not soluble in such liquid such as nucleic acids, proteins, cells, or the like, or an amount of non-biological particles whether soluble or not such as an element, a molecule whether organic or inorganic, a salt, beads, or the like, or mixtures, combinations or permutations thereof.

For the purposes of the present invention, the term “a” or “an” entity refers to one or more of that entity; for example, “a valve” refers to one or more valves(s) or at least one valve. As such, the terms “a” or “an”, “one or more” and “at least one” can be used interchangeably herein. Furthermore, the term “selected from the group consisting of” refers to one or more of the related elements in the list that follows, including combinations of two or more of the listed elements.

Ranges may be expressed herein as from “about” one particular value to “about” another particular value. When such a range is expressed, one embodiment of the invention includes from approximately the one particular value to approximately the other particular value and another embodiment includes from the one particular value to the other particular value. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independent of the other endpoint. Similarly, when a value is expressed as an approximation by use of the antecedent “about,” it will be understood that an embodiment of the invention includes approximately the particular value while the particular value forms another embodiment of the invention.

The inventive method can further include the step of coupling the inventive valve (1) to the fluid source (3) to generate the enclosed space (4) which can contain an amount of fluid (2). Coupling of the inventive valve (1) to the fluid source (3) can be achieved by engaging matable surfaces provided by a part of the fluid source (3) and a part of the valve (1).FIGS. 1 and 9provide non-limiting examples of the inventive valve (1) coupled to the fluid source (3). The amount of fluid (2) when provided as an amount of liquid (5), as shown inFIG. 1, can be any amount of liquid (5) of lesser amount than the volume defined by the enclosed space (4) of the fluid source (3).

Now referring primarily toFIGS. 2 and 3, the inventive method can further include the step of operating a valve trigger (6). Operating a valve trigger (6), for the purposes of the invention means generating travel of a valve trigger (6) slidely or telescopically engaged in a valve trigger guide (22) of a valve housing (17). For the purposes of the present invention, “a valve trigger (6)” has a configuration capable of generating coincident operation (contemporaneous occurrence of events) of a fluid delivery passage seal (7) and a fluid compensation passage seal (8) in corresponding relation to a fluid delivery passage seat (18) and a fluid compensation passage seat (19) to provide the corresponding open condition (9) and closed condition (10) of a fluid delivery passage (11) and a fluid compensation passage (12)(seeFIG. 2which shows the closed condition (9) andFIG. 3which shows the open condition (10)). By establishing the open condition (9) of the fluid delivery passage (11) and the open condition (10) of the fluid compensation passage (12) (also referred to as the open condition (10) and the closed condition (11) of the valve (1)) coincident fluidic coupling of the fluid delivery passage (11) and the fluid compensation passage (12) can be established with the fluid source (3). The term “fluid delivery passage (11)” for the purposes of this invention means a passage having a configuration which provides a fluid delivery flow path (13) through which an amount of fluid (2)(whether a gas or a liquid) can flow (20)(as indicated by the arrow shown inFIG. 3have reference numeral (20)) from a fluid source (3) to a valve outlet orifice (15) of a valve outlet (45). The term “fluid compensation passage (12)” for the purpose of this invention means a passage having a configuration which provides a fluid compensation flow path (14) through which an amount of compensation fluid (16)(whether a gas or a liquid) can provide a compensating flow (21) to the fluid source (3). The term “coincident fluidic coupling” for the purposes of this invention means the contemporaneous occurrence of events which establishes a fluid delivery passage (11) with a fluid source (3) and establishes a fluid compensation passage (12) with a fluid source (3); however, the duration of the event which establishes the fluid delivery passage (11) with the fluid source (3) and the duration of the event which establishes the fluid compensation passage (12) with the fluid source (3) can but need not share the entirety of the same period or phase, but rather the duration of the event which establishes the fluid delivery passage (12) with the fluid source (3) and the duration of the event which establishes the fluid compensation passage (12) need only share a part of the same period or phase or range.

Now referring primarily toFIG. 3, the inventive method can further include the steps of delivering a flow (20) of an amount of fluid (2) from the fluid source (3) through a fluid delivery passage (11) to exit from a valve outlet orifice (15)(or establishing a fluid delivery passage (11) between a valve inlet orifice (24) and a valve outlet orifice (15)) while coincidently generating a compensating flow (21) of an amount of compensation fluid (16) through the fluid compensation passage (12) into the enclosed space (4) of the fluid source (3)(or establishing a fluid compensation passage between a fluid compensation inlet orifice (53) and a fluid compensation outlet orifice (54)). The term “an amount of compensation fluid (16)” for the purposes of this invention means an amount of gas, whether a mixture of gases such as air, or other mixture of partial pressures of gases, or an amount of a single gas or substantially a single gas such as nitrogen, oxygen, argon, or the like, or an amount of liquid such as an amount of water, an amount of a solution which provides an amount of solute in an amount of solvent, an amount of fuel such as gasoline, diesel fuel, bio-diesel, or the like, an amount of alcohol such as methanol, ethanol, or isopropanol, or the like, and can further encompass an amount of liquid which entrains an amount of biological particles whether or not soluble in such liquid such as nucleic acids, proteins, cells, or the like, or an amount of non-biological particles whether soluble or not such as an element, a molecule whether organic or inorganic, a salt, or the like, or combinations and permutations thereof.

Now referring primarily toFIGS. 2 and 3, the inventive method can further include the step of providing a valve housing (17) which can have a variety of constructional forms that each define the fluid delivery passage (11) and the corresponding fluid delivery flow path (13) and define the configuration of the fluid compensation passage (12) and the corresponding fluid compensation flow path (14). The step of providing a valve housing (17) can further include the step of locating a fluid delivery passage seat (18) within the fluid delivery passage (11) and locating a fluid compensation passage seat (19) in the fluid compensation passage (12) which correspondingly engage the fluid delivery passage seal (7) and the fluid compensation passage seal (8) to coincidently interrupt the step of delivering a flow (20) and interrupt the step of compensating flow (21) in the closed condition (9) of the valve (1) and can correspondingly disengage from the fluid delivery passage seal (7) and the fluid compensation passage seal (8) to provide the steps of delivering a flow (20) and compensating a flow (21) in the open condition (10) of the valve (1).

The step of providing a valve housing (17) can further include the step of providing a trigger guide (22) configured to allow sliding or telescopic engagement of the valve trigger (6) to guide the valve trigger (6) along a valve trigger path (23) to generate coincident operation of the fluid delivery passage seal (7) and the fluid compensation passage seal (8) in relation to the corresponding fluid delivery passage seat (18) and fluid compensation passage seat (19) to provide the corresponding open condition (9) and closed condition (10) of the valve (1). As to certain embodiments of the inventive valve (1), the step of providing a trigger guide (22) can further comprise the step of providing a valve trigger stem guide (55) discrete from a valve trigger compensation stem guide (56). As to those embodiments, the step of operating a valve trigger (6) can further comprise operating a valve trigger (6) configured to include a valve trigger stem (36) having a first valve trigger stem end (38) coupled to the valve trigger (6) and a second valve trigger stem end (38) coupled to said fluid delivery passage seal (7) which slidly or telescopically engages the valve trigger stem guide (55) and a discrete valve trigger compensation stem (41) having a first valve trigger compensation stem end (42) coupled to said valve trigger (6) and a second valve trigger compensation stem end (43) coupled to the fluid compensation passage seal (8) which slidely or telescopically engages the valve trigger compensation stem guide (56).

Now referring primarily toFIGS. 4-8, the above-described method can be practiced with various embodiments of the inventive valve (1) each of which provides a valve housing (17) and a valve trigger (6). While the valve housing (17) and valve trigger (6) shown byFIGS. 4-8provides particular example of a valve housing external surface configuration (25) and a particular example of a valve trigger external surface configuration (26), the invention is not so limited, and the valve housing (17) and the valve trigger (6) can afford a numerous and wide variety of external surface configurations which are capable of functioning in accordance with the above-described method.

Accordingly, and referring primarily toFIGS. 2 and 3, embodiments of the valve housing (17) have an internal surface configuration which in part provides a valve trigger guide (22) which defines a valve trigger path (23). A part of the external surface of the valve trigger (6) slidingly (also referred to as telescopically) engages the valve trigger guide (22) to allow travel (27)(shown by arrow inFIG. 3having reference numeral (40)) of the valve trigger (6) along the valve trigger path (23). As shown inFIGS. 2 and 3, a part of the valve trigger (6) can extend beyond the boundary of the external surface of the valve housing (17) for engagement by a valve operator (28)(shown as the arrow having the reference numeral (28)). The valve operator (28) can be any person or mechanical device capable of operating the valve trigger (6), to function as above described. The valve operator (28) by engaging that part of the valve trigger (6) which extends beyond the valve housing (17) can by forcible urging generate inward travel (27)(shown InFIG. 3as the arrow having the reference numeral (27)) of the valve trigger (6) along the valve trigger path (23). The valve trigger (6) can further provide a first valve trigger stop (28) which upon travel of the valve trigger (6) a distance along the valve trigger path (23) can engage a part of the external surface of the valve housing (17) to prevent further inward travel (27) of the valve trigger (6) along the valve trigger path (23). Forcible urging by the valve operator (28) of the valve trigger (6) inwardly along the valve trigger path (23) can be opposed by a valve trigger bias element (29).

The valve trigger bias element (29) shown inFIGS. 2 and 3has the constructional form of a coil spring (30) having a first coil spring end (31) which engages the valve trigger (6) and a second coil spring end (32) which engages a part of the internal surface of the valve housing (17); however, the invention is not so limited, and the valve trigger bias element (29) can be of any constructional form which sufficiently opposes inward travel (27) of the valve trigger (6) along the valve trigger path (23) to generate travel (27) outwardly along the valve travel path (23) of the valve trigger (6) when disengaged by the valve operator (28). The valve trigger (6) can further include a trigger seal (51). The trigger seal (51) engages the valve trigger (6) and slidly sealably engages the valve trigger guide (22) to prevent transfer or reduce transfer of any part of the flow (20) of an amount of fluid (2)(or liquid (5)) in the fluid delivery passage (11) between the engaged surfaces of the valve trigger (6) and the valve trigger guide (22). A trigger seal (51) which can be utilized with the inventive valve (1) is a C-cup O-ring; however, the invention is not so limited, and any manner of seal which can slidly sealably engage the valve trigger guide (22) to prevent transfer or reduce transfer of any part of the flow (20) of an amount of fluid (2)(or liquid (5)) between the engaged surfaces of the valve trigger (6) and the valve trigger guide (22), can be utilized.

Again referring primarily toFIGS. 2 and 3, the internal surface configuration of the valve housing (17) can further define the configuration of fluid delivery passage (11) and the fluid delivery flow path (13) and the fluid compensation passage (12) and the fluid compensation flow path (14). The fluid delivery passage (11) and the fluid compensation delivery passage (12) in the open condition (9) of the valve (1) afford discrete passages each of which fluidly couple the enclosed space (4) in the fluid source (3) to the space outside of the fluid source (3). In the example shown, the space outside of the fluid source (3) comprises the atmosphere (33).

The internal surface configuration of the valve housing (17) can further define the configuration of a fluid delivery passage seat (18) coupled within the fluid delivery passage (11). A fluid delivery passage seal (7) has a configuration which can sealably engage the fluid delivery seat (18) coupled to the fluid delivery passage. Sealable engagement of the fluid delivery passage seal (7) to the fluid delivery passage seat (18) establishes the closed condition (10) of the fluid delivery passage (11) and the valve (1), as shown inFIG. 2. Disengagement of the fluid delivery seal (7) from the fluid delivery passage seat (18) establishes the open condition (9) of the fluid delivery passage (11) and the valve (1) fluidly coupling the enclosed space to atmosphere (33). The fluid delivery passage seal (7) can further include a resiliently flexible seal element (34) which assists in establishing the seal with the between the fluid delivery passage seal (7) and the fluid delivery passage seat (18).

The internal surface configuration of the valve housing (17) can further define the configuration of a fluid compensation passage seat (19) coupled within the fluid compensation passage (12). A fluid compensation passage seal (8) has a configuration which can sealably engage the fluid compensation passage seat (18) coupled to or a part of the fluid compensation passage (12). Sealable engagement of the fluid compensation passage seal (8) to the fluid compensation passage seat (19) establishes the closed condition (10) of the fluid delivery passage (11) as shown inFIG. 2. Disengagement of the fluid compensation passage seal (8) from the fluid compensation passage seat (18) establishes the open condition (9) of the fluid delivery passage (11) fluidicly coupling the enclosed space (4) to atmosphere (33). The fluid compensation passage seal (8) can further include a resiliently flexible compensation seal element (35)(such as a C-cup O-ring) which assists in establishing the seal with the between the fluid compensation passage seal (8) and the fluid compensation passage seat (19). As shown byFIGS. 2 and 3, a non-limiting embodiment of the fluid compensation seat (19) can comprise a part of the wall of the fluid compensation passage (12).

Now referring primarily toFIGS. 2 and 3, the fluid delivery passage seal (7) can be made responsive to travel (27) of the valve trigger (6) in the valve trigger guide (22). A non-limiting embodiment of the inventive valve (1), includes a valve trigger stem (36) having a first valve trigger stem end (37) coupled to the valve trigger (6) and a second valve trigger stem end (38) coupled to the fluid deliver passage seal (7). Inward travel of the valve trigger (6) in the valve trigger guide (22) as above-described correspondingly generates a sufficient amount of travel (39) in the fluid delivery passage seal (7) to disengage the fluid delivery passage seal (7) from the fluid deliver passage seat (18) to establish the open condition (9) of the fluid delivery passage (11) to fluidly couple the enclosed space (4) with the atmosphere (33). Outward travel of the valve trigger (6) in the valve trigger guide (22) as above-described correspondingly generates a sufficient amount of travel (39) in the fluid delivery passage seal (7) to engage the fluid delivery passage seal (7) to the fluid deliver passage seat (18) to establish the closed condition (10) of the fluid delivery passage (11) to fluidly uncouple the enclosed space (4) from the atmosphere (33). Travel of the valve trigger (6) from a first position which establishes the closed condition (10) of the fluid delivery passage (11) toward a second position which establishes the open condition (9) of the fluid delivery passage (11) allows a variably adjustable delivery of the flow (20) through the fluid delivery flow path (13).

In the particular embodiment of the valve (1) shown inFIGS. 2 and 3, the valve trigger housing (17) defines a configuration which disposes a longitudinal axis (57) of the valve trigger stem guide (55) in substantially perpendicular relation to a longitudinal axis (58) of a first part (59) of the fluid delivery passage (11). Accordingly, the valve trigger stem (36) having first valve trigger stem end (37) coupled to the valve trigger (6) can be disposed in perpendicular relation within a first part (59) of the fluid delivery passage (11). The first part (59) of the fluid delivery passage (11) can terminate in a closed end (60) with the fluid delivery passage seat (18) providing an aperture (61) which communicates between opposed surfaces of a fluid delivery passage wall (62) of the fluid delivery passage (11). The valve trigger stem (36) extends through the aperture (61) of the fluid delivery passage seat (18). The valve delivery passage seal (7) couples to the second end (43) of the valve trigger stem (36) extending through the aperture (61) of the fluid delivery passage valve seat (18). Engagement of the fluid delivery passage seal (7) with the fluid delivery passage valve seat (18) generates a closed end (60) fluid delivery passage (11). Disengagement of the fluid delivery passage seal (7) from the fluid delivery passage seat (18) provides fluid communication through the aperture (61) of the fluid delivery passage seat (18) between opposed sides of the fluid delivery passage wall (62). The valve housing (17) further defines a second part (63) of the fluid delivery passage (11) disposed adjacent the first part (59) providing sufficient space for travel of the fluid delivery passage seal (7) and provides fluidic communication between the first part (59) of the fluid delivery passage (11) and the valve inlet orifice (24).

Again referring primarily toFIGS. 2 and 3, the fluid compensation passage seal (8) can also be made responsive to travel (40) of the valve trigger (6) in the valve trigger guide (22). A valve trigger compensation stem (41) has a first valve trigger compensation stem end (42) coupled to the valve trigger (6) and a second valve trigger compensation stem end (43) coupled to the fluid compensation passage seal (8). Inward travel of the valve trigger (6) in the valve trigger guide (22) as above-described correspondingly generates a sufficient amount of travel (40) in the fluid compensation passage seal (8) to disengage the fluid compensation passage seal (8) from the fluid compensation passage seat (18) to establish the open condition (9) of the fluid compensation passage (12) to fluidly couple the enclosed space (4) with the atmosphere (33). Outward travel of the valve trigger (6) in the valve trigger guide (22) as above-described correspondingly generates a sufficient amount of travel (40) in the fluid compensation passage seal (8) to engage the fluid compensation passage seal (8) to the fluid compensation passage seat (19) to establish the closed condition (10) of the fluid compensation passage (12) to fluidly uncouple the enclosed space (4) from the atmosphere (33).

In the non-limiting embodiment of the valve (1) shown inFIGS. 2 and 3, the valve housing (17) further defines a valve trigger compensation stem guide (56) discrete from the valve trigger stem guide (55), above described. The first valve trigger compensation stem end (42) of the valve trigger compensation stem (41) couples to the trigger (6) and slidely or telescopically engages the valve trigger compensation stem guide (56). The second valve trigger compensation stem end (43) of the valve trigger compensation stem (41) couples to the fluid compensation passage seal (8). The fluid compensation passage seal (8) shown has a cylindrical configuration which slidely engages a cylindrical fluid compensation passage seat (19). The cylindrical fluid compensation passage seat (19) also comprises a first portion (64) of the fluid compensation passage (12). Slidable engagement of the fluid compensation passage seal (8) with the compensation passage seat (19) also a first portion (64) of the fluid compensation passage (12) establishes the closed condition (10) of the fluid compensation passage (12)(shown inFIG. 2). A second portion (65) of the fluid compensation passage (12) communicates in perpendicular relation to the first portion (64) of the fluid compensation passage (12). This constructional form allows the fluid compensation seal (8) to travel outside of the fluid compensation passage seat (19)(also a first portion (64) of the fluid compensation passage (12)) establishing the open condition (9) of the fluid compensation passage (12) with the amount of compensation fluid (16) flowing about the valve trigger compensation stem (41) to establish a compensating flow (21) to the second portion (65) of the fluid compensation passage (12).

While each of the valve trigger stem (36) and the valve trigger compensation stem (41) shown in the Figures provide a generally cylindrical member coupled between the valve trigger (6) and the corresponding fluid deliver passage seal (8) and fluid compensation passage seal (8); the invention is not so limited and the valve trigger stem (36) and the valve trigger compensation stem (41) can be configured in any manner which allows each seal to travel (39)(40) responsive to the valve trigger (6) and establishes each seal (7)(8) at a location within the valve housing (17) which allows each to sealably engage and disengage the corresponding seat (18)(19) to establish the corresponding open condition (9) or closed condition (10) of each passage (11)(12) in response to travel (39) of the valve trigger (6) in the valve trigger guide (22).

Now referring primarily toFIGS. 2 and 3, the inventive valve (1) can further include a fluid compensation passage extension element (52). The fluid compensation passage extension element (52) can be a discrete element or unitary with the fluid compensation passage (12). As shown inFIGS. 2 and 3, a non-limiting embodiment of the fluid compensation passage extension element (52) can comprise a tube having sufficient length to extend to the bottom of the fluid source (3).

Now referring generally toFIGS. 1-6and specifically toFIGS. 7 and 8, the inventive valve (1) can further provide a valve inlet (44) and a valve outlet (45). The valve outlet (45) can provide a valve outlet external surface (46) configured to mate with a conduit (47)(seeFIG. 1). As shown in the a non-limiting exampleFIGS. 4-6, the valve outlet external surface (46) can further provide one or a plurality of hose barbs (48). A length of tubular conduit (47) or hose having an internal diameter of about the outside diameter of the valve outlet (45) and having a sufficiently flexible wall can be slidely engaged with the hose barbs (48) to connect the conduit (47) to the valve outlet (45). However, the inventive valve (1) is not so limited and the valve outlet external surface (46) or the valve outlet (45) can be configured in any manner which can be coupled with a conduit (47)(for the purposes herein “a conduit” is a member which provides a passage through which a fluid can flow such as a hose or a tube) by the provision of matable fitting such as providing spiral threads, compressibly mated fittings, insertably mated sockets, or the like.

Similarly, the valve inlet (44) can provide a valve inlet external surface (49) configured to mate with the fluid source (3). As shown inFIGS. 2-4, a particular embodiment of the inventive valve (1) can provide a spirally threaded valve inlet external surface (49) configured to mate with a spiral thread of a fluid source outlet (50). However, the inventive valve (1) is not so limited and the valve inlet external surface (49) or the valve inlet (44) can be configured in any manner which can be coupled with the fluid source outlet (50) by the provision of matable fitting such as providing spiral threads, compressibly mated fittings, insertably mated sockets, or the like.

Now referring primarily toFIG. 9, embodiments of the inventive valve (1) can provide a valve housing (17) configured to couple to fluid source outlet (50) of a fluid source (3). Coupling of the inventive valve (I) to the fluid source (3) can be achieved by engaging matable surfaces provided by a part of the fluid source (3) and a part of the valve (1). InFIG. 1, as one non-limiting example, the valve housing (17) was configured to provide a spirally threaded valve inlet external surface (49) configured to mate with a spiral thread of a fluid source outlet (50). InFIG. 9, as a second non-limiting example, the fluid source outlet (50) can be configured as an outwardly extending tubular member (66) having a spirally threaded tubular member external surface (67) which rotatingly receives a cap (68) having a spirally threaded cap internal surface (69)(or other matable surfaces). A cap aperture (70) can perforate the cap top (71). The cap aperture (70) can be sufficiently large to allow the spirally threaded portion of valve inlet (44) to pass through. An annular projection element (72) can coupled about the valve housing (17) at a location adjacent the spirally threaded (or other matable surface) of the valve inlet (44). A part of the external surface of the annular projection element (72) and the external surface of the cap (68) can engage to dispose the valve housing (17) in mated relation to the cap (68). The portion of spirally threaded valve inlet (44) extending through the cap aperture (70) can rotatingly receive a correspondingly spirally threaded fastener (73) which operationally draws the external surface of the annular projection element (72) adjacent a corresponding portion of the external surface of the cap ( ). As to certain embodiments of the invention, the external surfaces of the cap (68) and the annular projection element (72) can be sufficiently compressed by operation of the spirally threaded fastener (73) to sealably engage. As to other embodiments of the invention, a first seal member (74) can be located between the external surfaces of the annular projection element (72) and the cap (68) and a second seal member (75) can be located between the external surfaces of the cap (68) and the spirally threaded fastener (73). The cap (68) coupled to the valve (1) can be rotatingly engaged to the fluid source outlet (50). Understandably, these specific examples of coupling the inventive valve (1) to a fluid source (3) are intended to provide sufficient description for a person of ordinary skill in the art to couple the inventive valve (1) to a numerous and wide variety of fluid sources (3) which may have a wide variety of configurations of fluid source outlets (50).

As can be easily understood from the foregoing, the basic concepts of the present invention may be embodied in a variety of ways. The invention involves numerous and varied embodiments of an inventive valve system and methods of using such embodiments of the inventive valve system.
