Abstract:
One or more techniques and/or systems are disclosed for a nozzle that may allow the operator to adjust the flow rate of the fluid through a straight stream nozzle, while maintaining an open waterway. A nozzle may be devised that utilizes an adjustment motion common to operators of such a nozzle, where the adjustment motion allows the operator to switch between a fully open flow and a restricted flow. The fully open flow can provide a smooth bore straight profile stream of fluid at a higher flow rate, and the restricted flow can provide the smooth bore straight profile stream at a lower flow rate.

CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims priority to U.S. Provisional Patent Application Ser. No. 62/130,781, entitled ADJUSTABLE SMOOTH BORE NOZZLE, filed Mar. 10, 2015, which is incorporated herein by reference. 
     
    
     BACKGROUND 
       [0002]    Current smooth bore nozzles can provide a straight fluid stream. Typically, when a user wishes to alter a flow rate of fluid discharge from a nozzle, a stacked tip assembly is used. The stacked tip assembly utilizes a series of nozzle tips, of varying sizes, stacked in sequence to achieve a desired flow rate and discharge stream profile. The user typically shuts off the fluid supply, and one or more tips are removed and/or added to achieve the desired assembly. The resulting nozzle assembly can provide the desired straight stream profile, with the desired fluid discharge rate, and achieve a desired stream reach. 
       SUMMARY 
       [0003]    This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key factors or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. 
         [0004]    As provided herein, a fluid dispensing nozzle that can allow the operator to adjust a flow rate (e.g., in gallons or liters per minute) of the fluid dispensed from the nozzle, while maintaining a flow of fluid through the nozzle. That is, for example, the flow rate and/or stream profile may be adjusted without shutting down the fluid flow through the nozzle. A nozzle may be devised that utilizes an adjustment motion common to operators of such a nozzle, where the adjustment motion allows the operator to switch between an open flow and a restricted flow. The open flow can provide a smooth bore, straight stream profile of fluid at a higher flow rate, and the restricted flow can provide the smooth bore, straight stream profile at a lower flow rate. 
         [0005]    In one implementation, a nozzle can comprise a nozzle base that may be configured to operably couple a fluid flow control body with a nozzle tip. The nozzle base can comprise a base fluid passage, where the base fluid passage is defined by a cylinder having a first shape at its downstream, and a second shape at its upstream face. The nozzle tip can comprise a tip fluid passage that comprises an inlet face substantially similar to the first shape; and the base fluid passage can fluidly couple with the tip fluid passage to form a nozzle fluid passage. The nozzle tip or the nozzle base can be configured to rotate around a central axis of the nozzle between a passage alignment configuration and a passage non-alignment configuration, where the central axis of the nozzle is substantially parallel to the flow of fluid. 
         [0006]    In another implementation, a nozzle can comprise a nozzle base, which may comprise a base fluid passage defined by a cone-shaped passage, diverging in the direction of fluid flow. The nozzle base can be configured to selectably couple with a fluid flow control body and a nozzle tip. The nozzle tip can be configured to separate fluid flow from the nozzle base into an outer fluid stream and a central fluid stream, and subsequently merge the separated streams into a substantially straight stream pattern at a nozzle outlet portion. The nozzle tip can comprise a stream separator configured to separate the fluid flow into the outer fluid stream and central fluid stream. Further, the nozzle tip can comprise a discharge tube that is selectably coupled with the stream separator and configured to direct the central fluid flow to the fluid outlet. The shape of the outside surface of the discharge tube, in combination with an inner wall of the nozzle tip, can direct the outer fluid stream to a convergent path with the central fluid stream. Additionally, the nozzle tip can comprise a flow control sleeve that can be configured to translate between a forward and rearward position. The flow control sleeve can comprise a restrictor configured to restrict the outer fluid stream in conjunction with the outside surface of the discharge tube in the rearward position, and provide a substantially unrestricted outer fluid stream flow in the forward position.

These are indicative of but a few of the various ways in which one or more aspects may be employed. Other aspects, advantages and novel features of the disclosure will become apparent from the following detailed description when considered in conjunction with the annexed drawings.

     DETAILED DESCRIPTION 
       [0022]    The claimed subject matter is now described with reference to the drawings, wherein like reference numerals are generally used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the claimed subject matter. It may be evident, however, that the claimed subject matter may be practiced without these specific details. In other instances, structures and devices may be shown in block diagram form in order to facilitate describing the claimed subject matter. 
         [0023]    A nozzle may be devised that comprises a straight bore stream pattern fluid outlet, which can be adjusted between different fluid flow rates, while maintaining a fluid flow through the nozzle and discharging in a straight stream profile. That is, for example, fluid flow through the nozzle may not need to be shut down in order to adjust the fluid flow rate, and one or more stacked tips may not need to be removed or added. Further, the nozzle may allow a user to switch between different flow rates using a single motion that is common to users of such a nozzle (e.g., firefighters), such as a rotation of a portion of the nozzle, such as the nozzle tip or base. 
         [0024]    In one aspect, a portion of the fluid passage through the nozzle may comprises a non-circular shape, which, when adjusted (e.g., rotated) into a non-alignment position, can result in a restricted fluid flow through the passage. The nozzle base can comprise a base fluid passage that is defined by a cylinder having a first shape (e.g., a polygon, such as a triangle, square, pentagon, etc., a curved polygon, or ellipse (non-circle)) at its downstream face (e.g., end), and a second shape (e.g., ellipse, such as a circle) at its upstream face. Further, the nozzle can comprise the nozzle tip that may be configured to operably couple with the nozzle base. The nozzle tip can comprise a tip fluid passage that has an inlet face (e.g., at its upstream end) substantially similar to the first shape; and the base fluid passage can fluidly couple with the tip fluid passage to form the nozzle fluid passage. 
         [0025]    In one implementation, in this aspect, as illustrated in  FIGS. 1 and 2 , an example nozzle  100  can comprise a fluid flow control body  102  configured to control fluid flow into the nozzle. The fluid flow control body  102  can comprise a control actuator  104 , that is operably coupled to a fluid flow control element  202 . The fluid flow control element  202  is configured to control a flow of fluid  214  into the nozzle  100 . In this implementation, the fluid flow control body  102  is fluidly coupled with a fluid inlet  106 . The control actuator  104  can be configured to control the fluid flow control element  202 , for example, by controlling an amount of rotation of the fluid flow control element  202 . In one implementation, the control actuator  104  may be used to restrict fluid flow  214  (e.g., shut off fluid flow) to the nozzle  100 , or open fluid flow  214  to the nozzle  100 . In another implementation, the control actuator  104  may cause the flow of fluid  214  to be reduced through the nozzle  100 , for example, by throttling the control actuator  104  between an open and closed position. 
         [0026]    As a non-limiting example, a flow control element (e.g.,  202 ) may comprise one of the following types: a ball, butterfly, slide, piston, plug, globe, check, gate, and others. The flow control element  202  may take any form chosen in accordance with sound engineering judgment to stop, mitigate, reduce, or decrease fluid flow  214 . In one implementation, the fluid flow control element  202  may comprise a ball-type flow control element (“ball”). In this implementation, for example, a ball can be disposed proximate the fluid inlet  106  to the nozzle  100 , as illustrated in  FIGS. 2-5 , illustrating an example flow shutoff ball, shown in the open position (e.g., allowing fluid to flow into the nozzle). 
         [0027]    In one implementation, as illustrated in  FIGS. 1, 2, 3, 4, and 5 , an example nozzle  100  can comprise a nozzle base  108  and a nozzle tip  110 . The nozzle base  108  can be configured to selectably, operably couple with the fluid flow control body  102  and the nozzle tip  110 . For example, the nozzle base  108  may comprise a type of adaptor between the fluid flow control body  102  and the nozzle tip  110 . In another implementation, the nozzle tip may be configured to selectably, operably couple directly with the fluid flow control body  102 , for example, without utilizing the nozzle base  108 . 
         [0028]    The nozzle base  108  can comprise a base fluid passage  210 , and the nozzle tip  110  can comprise a tip fluid passage  212 . The nozzle tip fluid passage  212  can be configured to provide a smooth bore (e.g., smooth bore tip), fluid pattern at discharge of the fluid from the nozzle, which may provide a generally straight pattern stream of fluid from the outlet of the nozzle. As an example, the straight bore portion of the example nozzle  100  can comprise a generally straight tube configured to provide a substantially straight path for fluid from inside the nozzle to an outlet portion of the nozzle. In this way, pressurized fluid can be expelled from the nozzle in a generally straight stream pattern. 
         [0029]    A location where the base fluid passage  210  meets the tip fluid passage  212  may form an interface orifice area  204 , which may act as a restrictor component. The interface orifice area  204  can comprise an area where the outlet of the base fluid passage  210  meets the inlet for the tip fluid passage  212 . In one implementation, a shape and size of the interface orifice area  204  can be defined by a relationship between the base fluid passage  210  and the tip fluid passage  212 . In one implementation, a shape of a cylinder section defined by a plane intersecting the fluid passages  210 ,  212  at the orifice area  204 , and perpendicular to the axis of the fluid passages  210 ,  212 , can comprise a geometric shape that is not a circle, such as a polygon or ellipse. That is, for example, the shape of the intersecting plane at the interface orifice area  204  can comprise an ellipse, some type of polygon (e.g., triangle), or a curved polygon. 
         [0030]    In one implementation, as illustrated in  FIG. 8 , the interface orifice area  204  end of the respective fluid passages  210 ,  212  (e.g., the downstream face of the nozzle base  108 , and the upstream face of the nozzle tip  110 , respectively) can comprise an ellipse. In this implementation, as illustrated in  FIGS. 2, 3, 6A, and 7 , when the interface orifice area  204  end of the respective fluid passages  210 ,  212  are aligned in an alignment position, such as when the major axes of the two ellipses are aligned, the passages  212 ,  210  can provide a higher rate of fluid flow  214 , for example, without substantial restriction. As illustrated in  FIGS. 4, 5, and 6B , when the interface orifice area  204  end of the respective fluid passages  210 ,  212  are not aligned in a non-alignment position, such as where the major axes of the respective ellipses are perpendicular to each other, the interface orifice area  204  is restricted, acting as a restrictor component, and providing a restricted fluid flow  214 , thereby providing a lower flow rate for the nozzle. 
         [0031]    In one implementation, the nozzle tip  110  can be rotated (e.g., around a central axis that is substantially parallel to the fluid flow  214 ) between a non-restricted and restricted configuration, acting as a restriction actuator for the restriction component—the interface orifice area  204 . As one example, where the interface orifice area  204  comprises an ellipse in a non-restricted (e.g., unrestricted) configuration, the nozzle tip  110  can be configured to be rotated approximately ninety degrees (90°). In this example, rotating the nozzle tip  110  ninety degrees can dispose the interface orifice area  204  ends of the respective fluid passages  210 ,  212  between an alignment position (e.g., where the major axes of the ellipses are aligned), and a non-alignment position (e.g., where the major axes of the ellipses are perpendicular), thereby restricting fluid flow  214 . 
         [0032]    In another implementation, where the interface orifice area  204  comprises a triangle (e.g., or curve-sided triangle) in a non-restricted (e.g., unrestricted) configuration, the nozzle tip  110  can be configured to be rotated approximately sixty degrees (60°). In this implementation, rotating the nozzle tip sixty degrees can change the interface orifice area  204  between a non-restricted position, having unrestricted flow, and a restricted position, having restricted flow. Further, as another implementation, the interface orifice area  204  comprises a square (e.g., or curved square), which can be rotated approximately forty-five degrees; or a six-sided polygon (or some other polygon), which can be rotated thirty degrees. In yet another implementation, the nozzle base  108  may be configured to be rotated, relative to the nozzle tip  110 , thereby acting as the restriction actuator, acting upon the interface orifice area  204 . In this implementation, as described above, rotating the nozzle base  108  can dispose the orifice area  204  ends of the respective fluid passages  210 ,  212  between an alignment position, and a non-alignment position, thereby restricting fluid flow  214 . 
         [0033]    It will be appreciated that the shape and size of the faces of the passages  210 ,  212  on the transecting plane at the interface orifice area  204 , formed by the meeting of the base fluid passage  210  and the tip fluid passage  212 , is not limited to the examples described herein. It is anticipated that those skilled in the art may configure alternate shapes, such as non-regular shapes, which may be used in a similar manner. The shape and size of the interface orifice area  204  is merely used to describe how rotation of the nozzle tip  110  (e.g., and/or base  108 ) can result in the geometric alignment of the respective fluid passages  210 ,  212  to become misaligned, thereby providing a restricted flow through the nozzle; and where realigning the fluid passages&#39;  210 ,  212  openings can provide for open flow. 
         [0034]    In one implementation, as illustrated in  FIGS. 2, 8A, and 8B , the nozzle tip  110  can comprise a rotation restrictor channel  206  disposed on a proximal (e.g., upstream) face. The rotation restrictor channel  206  can be configured to operably couple with a rotation restrictor pin  802  disposed on a distal (e.g., downstream) face of the nozzle base  108 . Further, a length of the rotation restrictor channel  206  may determine an amount of rotation available for the nozzle tip  110  (e.g., or the nozzle base  108 ). That is, for example, the length of the rotation restrictor channel  206  can be configured to provide the desired amount of rotation (e.g., ninety, sixty, forty-five, thirty degrees, etc.), based on the geometry of the interface orifice area  204  ends of the respective fluid passages  210 ,  212 . 
         [0035]    In one implementation, as illustrated in  FIGS. 7, 8A, and 8B , the example nozzle tip  110  may operably couple with the nozzle base  108  by way of a bearing system. As an example, the nozzle tip  110  may comprise a bearing raceway  812 , disposed on an inner surface of a coupling portion  816  of the tip  110 . Further, the nozzle base  108  may comprise a bearing raceway  804  disposed on an outer surface of a coupling portion  818  of the base  108 . Additionally, in one implementation, one or more ball bearings  702  may be disposed in the respective raceways  804 ,  812  when the base  108  is coupled with the tip  110 . In one implementation, for example, nozzle  100  may comprise one or more O-rings  704 , such as disposed between the base  108  and tip  110 , where the respective coupling portions  816 ,  818  couple together. As an example, the O-ring  704  may be disposed in an O-ring channel  806 , such as disposed in/on one or more of the respective coupling portions  816 ,  818 . 
         [0036]    In one implementation, as illustrated in  FIGS. 2, 3, 4, 6A, 6B, 7 and 8 , the example nozzle  100  can comprise an air inlet  302 , which may be configured to allow air to enter the nozzle  100  when the nozzle  100  is disposed in a restricted configuration (e.g.,  FIG. 4 ). For example, when the nozzle tip  110  (e.g., or base) is rotated such that the shaped (e.g., first shape) downstream face of the base fluid passage  210  and upstream face of the tip fluid passage  212  are not in the alignment position (e.g., non-alignment position in a restricted configuration, as in  FIGS. 4, 5, and 6B ), outside air may enter through the air inlet  302  and become entrained into the fluid flow  214  in the tip fluid passage  212 . In this implementation, introducing air into the tip fluid passage  212 , such as at the upstream end of the tip fluid passage  212 , may help mitigate turbulence that could result from a vacuum created eddy, which can strip water away from the center stream profile. That is, for example, instead of water trying to fill a void created by the misalignment of the geometric fluid passages  210 ,  212 , the introduction of air can help maintain a desired center stream profile, resulting in an improved divergent fluid stream at the outlet of the nozzle. 
         [0037]    For example, the nozzle tip  110  can comprise an intake air inlet  302  that is fluidly coupled with an air check valve  304  configured to merely allow air to flow into the nozzle tip  110 , and mitigate flow of fluid out of the air inlet  302  (e.g., a one-way check valve). As illustrated in  FIGS. 4, 8A and 8B , the nozzle tip can comprise an air passage  814 , that is fluidly coupled with the air inlet  302 . The tip air passage  814  can be configured to align with a base air inlet  810 , such as when the tip (e.g., or base) is rotated into the restricted configuration. In this implementation, the base air inlet  810  can be fluidly coupled with a base air outlet  808 , through a base air passage  208 . The base air outlet  808  can be configured to provide air to the nozzle tip passage  212  when the nozzle tip  110  is disposed in the restricted configuration. Further, for example, when the nozzle tip  110  is disposed in an unrestricted configuration, the base air outlet  808  may not be fluidly coupled with the tip fluid passage  212 , and/or the tip air passage  814  may not be fluidly aligned with the base air inlet  810 . In this example, air may not enter into the tip fluid passage  212 . 
         [0038]    In another aspect of a nozzle devised to adjust between higher and lower fluid flow rates while maintaining fluid flow in a smooth bore stream profile, the nozzle may have a fluid passage that comprises two pathways. In this aspect, the nozzle may be adjusted using a simple and routine motion (e.g., rotation) that can result in restriction of one of the two fluid flow pathways, thereby alternating between an open and restricted flow. 
         [0039]    In one implementation, in this aspect,  FIGS. 9-13  illustrate one or more portions of an example nozzle  900 , which may provide a smooth bore fluid profile, and may be adjustable between a higher flow rate and lower flow rate. The example, nozzle  900  can comprise a fluid flow control body  902  operably coupled with a fluid inlet coupler  908 . The fluid flow control body  902  can comprise a fluid flow control element  1002  coupled with a control actuator  910 , which can be configured to control the fluid flow control element  1002 . In one implementation, the control actuator  910 , coupled with the fluid flow control element  1002 , may be used to restrict (e.g., shut off) fluid flow  1010  for the nozzle  900 , or open fluid flow  1010  for the nozzle  900 . In another implementation, the control actuator  910  may cause the flow of fluid  1010  to be reduced through the nozzle  900 , for example, by throttling the shutoff component fluid flow control element  1002  between an open and closed position. 
         [0040]    As illustrated, the example, nozzle can comprise a nozzle base  904  (e.g., an adapter) and a nozzle tip  906 . Further, the nozzle base  904  can be configured to selectably, operably couple with the fluid flow control body  902 , and the nozzle tip  906  can be configured to selectably, operably couple with the nozzle base  904 . Additionally, the nozzle base  904  can comprise a base fluid passage  1214 , defined by a base passage wall  1212 . In one implementation, the base fluid passage  1214  may be defined by a cone segment, with diverging walls in the direction of fluid flow  1010 , for example. In another implementation, the nozzle tip  906  may be configured to operably couple directly with the fluid flow control body  902 , for example, such that the nozzle base  904  may not be used. In another implementation, the nozzle base  904  may be fixedly engaged with (e.g., formed with or integral to) the nozzle tip  906 . In this implementation, the combination nozzle base  904 , nozzle tip  906  component can operably couple with the fluid flow control body  902 . 
         [0041]    In one implementation, the nozzle tip  906  can comprise a central fluid passage  1216  and an outer fluid passage  1218 . For example, the nozzle tip  906  can be configured to separate the flow of fluid  1010  into two divergent flow streams  1010   a ,  1010   b , which can subsequently converge into a single smooth bore fluid pattern at discharge from a flow control sleeve  1008 . The nozzle tip  906  can comprise a stream separator  1012  configured to divide the fluid flow  1010  between the central fluid passage  1216  and the outer fluid passage  1218 . 
         [0042]    In one implementation, as illustrated in  FIGS. 10-13 , the stream separator  1012  can be fixedly engaged with a nozzle body  1204  portion of the nozzle tip  906 . Further the stream separator  1012  can comprise a discharge tube coupler  1210 , configured to selectably couple with a discharge tube  1202 , which may be configured to provide a smooth bore stream pattern. In one or more implementations, a discharge tube  1202  may be selected for a desired stream profile, and/or a desired water inlet size. That is, for example, the discharge tube  1202  may be available in a variety of sizes configured to accommodate a desired fluid output (e.g., and/or fluid input) profile. As an example, typical firefighting nozzles are described by particular diameter size properties, such as ¾ inch, ⅞ inch, and 1⅛ inch, and more. In this example, in order to accommodate a same expected output as a particular size nozzle tip, the discharge tube  1202  can be sized accordingly (e.g., sized in combination with a size of the outer fluid passage  1218  to achieve the desired stream profile and output). 
         [0043]    The stream separator  1012  coupled with the discharge tube  1202 , forming the central fluid passage  1216 , can be configured to provide a straight, smooth (e.g., smooth bore tip) fluid pattern at discharge of the fluid from the nozzle  900 . The smooth bore tip can typically provide a generally straight pattern stream of fluid from the outlet of the nozzle. As an example, the straight bore, central fluid passage  1216  portion of the example nozzle  900  can comprise a generally straight tube configured to provide a straight path for fluid from inside the nozzle to an outlet portion of the nozzle, in the control sleeve  1008 . In this way, pressurized fluid can be expelled from the nozzle in a generally straight stream pattern. 
         [0044]    An upstream portion of the stream separator  1012  can comprise a tapered lip portion, tapering toward the upstream end, and diverging toward the outer fluid passage  1218 . In combination with the divergent tapering base passage wall  1212 , the tapered lip portion of the discharge tube coupler  1210  can form the beginning of the outer fluid passage  1218 . The upstream portion of the stream separator  1012  can be configured to divert at least a portion of the fluid flow  1010  to the outer passage fluid flow  1010   a . In this implementation, the downstream portion of the exterior of the stream separator  1012  and the discharge tube  1202  can comprise a convergent taper, converging toward the downstream end, which, along with the nozzle body  1204  and flow control sleeve  1008 , form the downstream portion of the outer fluid passage  1218 . 
         [0045]    In one implementation, the angle of slope, amount of gap, and length of slope of the respective outer fluid passage  1218  (e.g., tapered lip portion of stream separator  1012 , tapering base passage wall  1212 , convergent taper of the downstream portion of the outer fluid passage  1218 , and combination of the inner wall of the nozzle body  1204  and the flow control sleeve  1008 ) may help provide a desired fluid flow characteristic, such as flow rate, pressure, stream profile and more. As an example, the output flow fluid characteristic of the outer fluid passage  1218  may approximate the output fluid flow characteristics of the central fluid passage  1216  in order to provide a desired convergent straight stream profile at output from the nozzle. 
         [0046]    Further, in this implementation, the flow control sleeve  1008  comprises a restrictor component  1220  that is configured to define an outer fluid passage gap  1006 . The restrictor component  1220  can comprise an extension of the flow control sleeve  1008 , extending into the outer passage. For example, the disposition of the flow control sleeve  1008  relative to the nozzle body  1204  may, at least in part, define the fluid passage gap  1006 . That is, for example, when the flow control sleeve  1008  is disposed in a forward position (e.g.,  FIG. 10 ), a gap  1006  between the restrictor component  1220  and the outer wall of the discharge tube  1202  may comprise a less restricted fluid flow (e.g., high flow rate). Additionally, in this example, when the flow control sleeve  1008  is disposed in a rearward position (e.g.,  FIGS. 11 and 12 ), the gap  1006  between the restrictor component  1220  and the outer wall of the discharge tube  1202  may comprise a more restricted fluid flow (e.g., low flow rate), essentially limiting fluid flow  1010   a  through the outer passage to the outlet. In this way, in this example, when the flow control sleeve  1008  is disposed in a rearward position, providing the restricted fluid flow, a lower fluid flow rate may be provided to the outlet of the nozzle  900 , while maintaining a straight stream discharge pattern. 
         [0047]    In one implementation, the flow control sleeve  1008  can be operably engaged with an outer sleeve  1206 , which can act as a restrictor actuator, and can be further operably engaged with a bumper  1004  at the outer surface of the nozzle tip  906 . Further, in this implementation, the nozzle body  1204  can be selectably engaged with the nozzle base  904  (e.g., which is engaged with the fluid flow control body  902 ). Additionally, the nozzle body  1204  can be slidably engaged with the flow control sleeve  1008 , such that the flow control sleeve  1008  can slide forward and rearward (e.g., and rotate) with respect to the nozzle body  1204 . That is, for example, the nozzle body  1204  can remain stationary relative to the nozzle base  904 , while the flow control sleeve  1008  may translate forward and rearward, relative to the nozzle body  1204 . 
         [0048]    In one implementation, the outer sleeve  1206 , acting as the restriction actuator, which is engaged with the flow control sleeve  1008 , may be driven by a cam system  1208 , comprising a cam insert that is configured to provide a particular distance of translation of the flow control sleeve  1008  when rotation (e.g., one-hundred and eighty degrees) is applied. That is, for example, the cam system  1208  may comprise a thread (e.g., spiral) pattern disposed on the nozzle body  1204  (e.g., with a lead or pitch for a single start thread) that provides for a desired flow control sleeve translation (e.g., desired distance forward and rearward), which can allow the flow control sleeve to more forward and rearward along the nozzle body, thereby adjusting a position of the restrictor component  1220 , and therefore the gap  1006  in the outer fluid passage  1218 . 
         [0049]    In one implementation, the cam system  1208  can comprise a component that couples the outer sleeve  1206  to the nozzle body  1204 , by way of a thread channel that is disposed in the nozzle body  1204 . That is, for example, a cam insert may be engaged with the outer sleeve  1206  and may also be slidably engaged with the thread channel disposed on the exterior of the nozzle body  1204 . In this implementation, the thread channel may be disposed around the perimeter of the nozzle body  1204  in a thread pattern (e.g., spiral pattern), comprising the desired thread lead (e.g., spiral pitch). In this example, when a rotational force is applied to the outer sleeve  1206 , such as by rotating an attached bumper  1004  engaged with the outer sleeve  1206 , the coupled cam insert can translate spirally in the thread channel to convert the rotational force into a lateral movement of the flow control sleeve  1008  with respect to the nozzle body  1204  and the discharge tube  1202 . 
         [0050]    As illustrated in  FIGS. 10 and 11 , in one implementation, rotating the outer sleeve  1206  can result in linear translation of the flow control sleeve  1008 , for example, while the engaged discharge tube  1202  and nozzle body  1204  remain stationary. In this implementation, linear translation of the outer sleeve  1206  can change the gap  1006  between the restrictor component  1220  and discharge tube  1202 , between a restricted (e.g.,  FIG. 11 ) and unrestricted (e.g.,  FIG. 10 ) configuration. In  FIG. 10 , the flow control element  1002  is disposed in an open position, allowing fluid flow  1010  from the inlet  908  into the example nozzle  900 . The fluid flow  1010  is divided into the outer flow stream  1010   a  and central fluid low stream  1010   b  by the upstream portion of the discharge tube coupler  1210 , comprising a diverging profile in combination with the base passage wall  1212 . With the flow control sleeve  1008  disposed in the forward (e.g., or downstream) position, the restrictor component  1220  provides a less restricted gap  1006 , allowing the fluid flow  1010   a  to converge with the central fluid flow  1010   b  at substantially a same flow rate and/or flow characteristic (e.g., speed, pressure, etc.), resulting in a substantially straight stream profile at a higher flow rate. In  FIG. 11 , the flow control sleeve  1008  is disposed in the rearward (e.g., or upstream) position, effectively, at least partially, restricting the outer fluid flow  1010   a  with the restrictor component  1220  creating a more restricted gap  1006  in combination with the discharge tube  1202 . In this way, for example, the fluid flow from the nozzle  900  may merely comprise the central fluid flow  1010   b  in a straight stream profile at a lower flow rate.
