[0001] This document relates to a fluid coupling device for a fluid system and a method of using the same. For example, some embodiments described herein relate to a fluid coupling device configured modularly and to modules that can be generally incorporated into the configuration of a plurality of different types of fluid couplings.

Background Art

[0002] Fluid systems generally include components such as tubes, pumps, reservoirs, fittings, couplings, heat exchangers, sensors, filters, valves, seals, etc. Such components can be selectively connected together within a network using fluid coupling devices that can be connected to define one or more fluid flow paths. Some fluid systems are closed systems, which means that the fluid recirculates within the network of components. Other fluid systems are open systems, which means that the fluid passes through the network of components just before exiting the network.

[0003] Fluid coupling assemblies typically include a female coupling and a male coupling that are releasably connected to each other to form a fluid flow path therethrough. Such coupling assemblies can be used in a variety of applications including biomedical applications, beverage dispensing, appliance connection, photochemical handling, liquid cooling, ink handling, and others.

[0004] In the context of some fluid systems, such as a fluid system for liquid cooling of an electronic device, it may be desirable to use a non-spill joint where fluid spillage is minimized or zero during connection and disconnection of male and female joints. Such a non-spill joint may, for example, serve to limit the exposure of the electronic device to fluids that may damage the electronic device. SUMMARY OF THE INVENTION MEANS FOR SOLVING THE PROBLEM

[0005] This document describes a fluid joint device for a fluid system and a method of using the same. For example, some embodiments described herein relate to a modularly configured fluid joint device and a module that can be generally incorporated into the configuration of a plurality of different types of fluid joints. In the context of the present disclosure, the term "fluid" includes both gases and liquids. The fluid joint device described herein is also referred to herein as a male joint and a female joint, and also as a "joint half" and / or a "connector", and the male joint is also referred to herein as an "insert", and the female joint is also referred to as a "body".

[0006] In some embodiments described herein, the fluid joint device described herein has a modular structure. That is, one or both of the joint halves can include a core module that can be used for various types of fluid joint outer bodies. In some embodiments, the core module includes a valve and one or more fluid seals.

[0007] In certain embodiments, the fluid joint device described herein is specifically designed using one or more mechanical components to configure the device as a "non-spill" joint device. Since the male and female parts of the joint device are connected to each other and / or not connected to each other, the device described herein is referred to as a non-spill joint device, and the design of the fluid joint device is intended to reduce the possibility of fluid discharge from the fluid system (e.g., by blocking the discharge path, etc.), and prevent outflows associated with the presence of fluid within the fluid joint device.

[0008] In one aspect, the present disclosure relates to a fluid coupling device including a fluid coupling housing defining a first opening that communicates with a coupling internal space defined within the fluid coupling housing. The fluid coupling device also includes a terminal extending onto a tip of the fluid coupling housing that is opposite the first opening from the fluid coupling housing. The terminal defines a second opening that communicates with the coupling internal space. The fluid coupling device also includes a fluid coupling module disposed within the coupling internal space. The fluid coupling module includes a module housing that defines a module internal space. The fluid coupling module also includes a valve stem secured to the module housing and extending within the module internal space along a longitudinal axis of the fluid coupling module. The fluid coupling module includes a valve sleeve disposed between the valve stem and the module housing. The valve sleeve is movable along the valve stem within the module internal space between (i) a closed position in which the valve sleeve seals the first opening from the second opening and (ii) an open position in which the first opening is fluidly connected to the second opening via the module internal space.

[0009] Such a fluid coupling device can optionally include one or more of the following features. The fluid coupling can also include an elastomeric seal disposed between the module housing and the fluid coupling housing. The fluid coupling device can also include (i) a first elastomeric seal disposed between the valve stem and the valve sleeve while the valve sleeve is in the closed position, (ii) a second elastomeric seal disposed between the valve sleeve and the module housing while the valve sleeve is in the closed position, and (iii) a third elastomeric seal disposed within the module internal space and disposed between the second elastomeric seal and the first opening. In some embodiments, most of the inner diameter surface of the third elastomeric seal is spaced from the valve sleeve while the valve sleeve is in the closed position. The fluid coupling device can also include an annular spacer disposed between the second and third elastomeric seals. The valve stem can include a base fixed to the module housing. The base can define an opening that fluidly connects the second opening to the module internal space. In some embodiments, the openings each include four openings shaped as quarter circles. The valve stem may include a base fixed to the module housing, and the fluid coupling may also include a spring disposed between the base and the valve sleeve that biases the valve sleeve toward the closed position. Further, the fluid coupling device may include a latch mechanism adjacent to the first opening. The latch mechanism may be laterally movable relative to the fluid coupling housing between (i) a latched position where the center of the opening defined by the latch mechanism is laterally offset relative to the center of the first opening, and (ii) an unlatched position where the opening defined by the latch mechanism is concentric with the first opening. Further, the fluid coupling device may include a spring between the latch mechanism and the fluid coupling housing that biases the latch mechanism toward the latched position.

[0010] In another aspect, the present disclosure relates to a fluid coupling module. The fluid coupling module includes a module housing that defines an internal space and a longitudinal axis. The module housing includes (i) a first end that defines a first end opening that communicates with the internal space, and (ii) a second end that defines a second end opening that communicates with the internal space. The fluid coupling module also includes a valve stem having a base fixed to the second end of the module housing. The valve stem extends along the longitudinal axis from the base toward the first end. The fluid also includes a valve sleeve disposed between the valve stem and the module housing. The valve sleeve is movable within the internal space along the valve stem between (i) a closed position in which the valve sleeve seals the first end opening from the second end opening, and (ii) an open position in which the first end opening is fluidly connected to the second end opening.

[0011] Such a fluid coupling module can optionally include one or more of the following features. The base can define an opening that fluidly connects the second end opening to the internal space. In some embodiments, the openings each include four openings shaped as quarter circles. The valve stem can also include a head at the end of the valve stem opposite the base. The head can define an annular seal groove configured to receive an elastomeric seal. The fluid coupling module also can include (i) a first elastomeric seal disposed within the annular seal groove and contacting the inner diameter of the valve sleeve while the valve sleeve is in the closed position, (ii) a second elastomeric seal disposed between the outer diameter of the valve sleeve and the module housing while the valve sleeve is in the closed position, and (iii) a third elastomeric seal disposed within the module internal space and between the second elastomeric seal and the first end opening. The fluid coupling module can also include an annular spacer disposed between the second and third elastomeric seals. The annular spacer can be in contact with each of the second and third elastomeric seals. Also, the fluid coupling module can include a spring disposed between the base and the valve sleeve that biases the valve sleeve toward the closed position.

[0012] In another aspect, the present disclosure is directed to a fluid coupling assembly. The fluid coupling assembly includes a male coupling and a female coupling that are releasably connectable to each other. The male coupling includes a male housing that defines an internal space and a longitudinal axis. The male coupling also includes a male coupling valve member that is slidable within the internal space along the longitudinal axis of the male housing, between (i) an open position in which a first tip of the male housing is fluidly connected to a second end of the male housing through the internal space of the male housing, and (ii) a closed position in which the male coupling valve member fluidly blocks the first tip of the male housing from being fluidly connected to the second end of the male housing. The female coupling includes a female housing that defines a first opening that communicates with an internal space defined within the female housing. The first opening is configured to receive a tip of the male housing. The female coupling also includes a terminal end that extends from the female housing at a tip of the female housing opposite the first opening. The terminal end defines a second opening that communicates with the internal space of the female housing. The female coupling also includes a fluid coupling module disposed within the internal space of the female housing. The fluid coupling module includes a module housing that defines a module internal space. The fluid coupling module also includes a valve stem that is secured to the module housing and extends within the module internal space along a longitudinal axis of the fluid coupling module. The fluid coupling module also includes a valve sleeve disposed between the valve stem and the module housing. The valve sleeve is movable along the valve stem within the module internal space between (i) a closed position in which the valve sleeve seals the first opening from the second opening, and (ii) an open position in which the first opening is fluidly connected to the second opening through the module internal space.

[0013] In some embodiments, the operation of the male coupling and the female coupling operably connecting the male coupling to the female coupling is configured such that (i) the male coupling valve member is moved from its closed position to its open position, and (ii) the valve sleeve is moved from its closed position to its open position, resulting in the generation of an open fluid flow path through the fluid coupling assembly via the internal space of the male housing and the module internal space.

[0014] In another aspect, the present disclosure relates to a fluid coupling device including a fluid coupling housing that defines a first opening that communicates with a coupling interior space defined within the fluid coupling housing and a second opening that communicates with the coupling interior space. The fluid coupling device also includes a fluid coupling module disposed within the coupling interior space. The fluid coupling module includes a module housing that defines a module interior space. The fluid coupling module also includes a valve assembly disposed within the module interior space. The valve assembly is configured such that (i) the first opening is in a closed position sealed from the second opening, or (ii) the first opening is in an open position fluidly connected to the second opening via the module interior space.

[0015] Certain embodiments of the subject matter described herein may be implemented to realize one or more of the following advantages. First, some embodiments of the fluid coupling device provide an improved spill-free connection and disconnection capability that can advantageously reduce or eliminate fluid spillage in some cases. Accordingly, these embodiments of the fluid coupling device described herein are well-suited for use in fluid systems that provide liquid cooling to electronic devices such as computers, for example. Another benefit from the non-spill design of the fluid couplings described herein is minimizing the inclusion of air into the fluid system when the couplings are connected to each other.

[0016] Second, in some embodiments, the fluid couplings are advantageously configured modularly. Such a modular structure can provide advantages such as manufacturing flexibility and user flexibility. For example, a single module can be designed to be used with fluid couplings of multiple different form factor types. Accordingly, the modular structure can facilitate the associated manufacturing efficiency advantages and reduction of inventory storage costs. Users of modular fluid couplings can also benefit from cost reduction due to the need to carry fewer and / or less expensive spare parts. hand.

[0017] Thirdly, some embodiments of the fluid coupling devices provided herein are advantageously designed using a robust latching system. That is, when two halves of a coupling are operably connected to each other to provide a fluid flow path therethrough, they are also mechanically locked together. In some embodiments, a thumb latch must first be depressed to unlock. This latching system can reduce the possibility of unintentional disconnect.

[0018] Fourthly, in some embodiments, the fluid coupling device can advantageously provide audible and / or tactile feedback to the user regarding the actions performed to physically separate the two parts of the fluid coupling device from each other. Such audible and / or tactile feedback can provide the user with an efficient and definitive indication or confirmation of the proper functioning and desired configuration of the fluid coupling device.

[0019] Fifthly, in some embodiments, the fluid coupling device can advantageously provide an indication of the temperature of the fluid inside the coupling by including a color-changing material (e.g., a thermochromic polymer) that responds to temperature.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. Further, the materials, methods, and examples described herein are illustrative only and not intended to be limiting.

[0021] Details of one or more embodiments of the invention are set forth in the accompanying drawings and the description herein. Other features, objects, and advantages of the invention will be apparent from the description and drawings, and from the claims.

DETAILED DESCRIPTION OF THE INVENTION

[0023] Referring to FIG. 1, some exemplary embodiments of the fluid coupling assembly 100 include a female coupling 110 and a male coupling 180 that are releasably connectable to each other. Here, the female coupling 110 and the male coupling 180 are depicted in their unconnected or disconnected arrangements. Although the female coupling 110 and the male coupling 180 are not connected (as shown), there is no open fluid flow path passing through either the female coupling 110 or the male coupling 180. Instead, as further described below, the valves within each of the female coupling 110 and the male coupling 180 are closed so that no fluid can flow through either the female coupling 110 or the male coupling 180.

[0024] In contrast to FIG. 1, FIGS. 24 - 26 (further described below) show the female coupling 110 and the male coupling 180 in a fully connected and operable arrangement. While the female coupling 110 and the male coupling 180 are in their fully connected arrangement, the fluid flow path 101 (FIG. 26) is opened and fluid can flow through the fluid coupling assembly 100 between the end portion 112 of the female coupling 110 and the end portion 182 of the male coupling 180. That is, the fluid flow path 101 is opened so that fluid can flow through each of the female coupling 110 and the male coupling 180 while the female coupling 110 and the male coupling 180 are in their connected arrangement. In other words, the end portion 112 of the female coupling 110 and the end portion 182 of the male coupling 180 are fluidly connected while the female coupling 110 and the male coupling 180 are in their connected arrangement.

[0025] The end portion 112 of the female coupling 110 and the end portion 182 of the male coupling 180 are shown as a bamboo - like connection, but it should be understood that the female coupling 110 and the male coupling 180 of the coupling halves can have any type of connection, such as a threaded connection, an elbow, a tee, a sanitary fitting, a compression fitting, etc., and combinations thereof, without being limited thereto.

[0026] Among the components of the fluid joint assembly 100, examples of the material from which one or more are made include thermoplastic resin and / or thermosetting resin. In certain embodiments, the material from which the components of the fluid joint assembly 100 are made is a thermoplastic plastic such as acetal, polycarbonate, polysulfone, polyetheretherketone, polysulfide, polyester resin, polyvinylidene fluoride (PVDF), polyethylene, polyphenylsulfone (PPSU; e.g., Radel (registered trademark)), polyetherimide (PEI; e.g., Ultem (registered trademark)), polypropylene, polyphenylene, polyaryl ether ketone, etc., and combinations thereof, but are not limited thereto. In some embodiments, the material from which one or more of the components of the fluid joint assembly 100 are made includes metals such as stainless steel, brass, aluminum, plated steel, etc., but are not limited thereto. In certain embodiments, one or both of the female joint 110 and the male joint 180 of the joint half do not contain metal. In some embodiments, one or both of the female joint 110 and the male joint 180 of the joint half include one or more metal spring members (e.g., spring steel, stainless steel, etc.). In certain embodiments, the fluid joint assembly 100 includes one or more gaskets or seals made of materials such as silicone resin, fluoroelastomer (FKM), ethylene propylene diene monomer (EPDM), thermoplastic elastomer (TPE), buna, buna-N, thermoplastic vulcanizate (TPV), etc., but are not limited thereto. In some embodiments, the joint or a part thereof can be constructed from a temperature-responsive color-changing material (e.g., a thermochromic polymer). Thus, the color of such a joint can provide an indication of the temperature of the fluid inside the joint.

[0027] It should be understood that the components of the fluid joint assembly 100 (e.g., the female joint 110 and the male joint 180) are scalable to substantially any desired size. Thus, the fluid joint assembly 100 can be scaled to connect a wide range of different tube sizes from very small tubes (e.g., having a diameter of 3 mm or less) to very large tubes (e.g., having a diameter of 50 mm or more).

[0028] Figures 2 and 3 show the female fitting 110 in further detail. The female fitting 110, which has been generally described, includes a female housing 120, a terminal end portion 112 extending from the female housing 120, and a fluid fitting module 140 disposed within an internal space defined by the female housing 120. The female housing 120 defines a first opening 122 configured to receive an end portion 184 of the male fitting 180 (see also FIG. 1). The terminal end portion 112 defines a second opening 113.

[0029] The female fitting 110 defines a longitudinal axis 111. In the illustrated embodiment, the terminal end portion 112, the fluid fitting module 140, and the first opening 122 are located at the center of the longitudinal axis 111.

[0030] The fluid fitting module 140 (shown separately in FIGS. 4-8) is a separate built-in component disposed within the female fitting 110 and can be considered to be separate. In other words, although the fluid fitting module 140 is depicted herein within the female housing 120 as part of the female fitting 110, it should be understood that the fluid fitting module 140 can be universally incorporated into a wide variety of different types of fluid fittings. In one additional non-limiting example, as will be further described below, the fluid fitting module 140 can be incorporated into a double female fluid fitting device 200 (as shown in FIGS. 9-11). In some cases, the fluid fitting module 140 may be a stand-alone product.

[0031] As shown, the female fitting 110 also includes an optional latch mechanism 130 and a spring 138. The latch mechanism 130 is operable to lock or latch the female fitting 110 and the male fitting 180 together in their fully connected configuration such that they can be released (e.g., as shown in FIGS. 24-26). In some embodiments, the latch mechanism is not included. Rather, the female fitting 110 and the male fitting 180 are joined together by other external forces applied to the female fitting 110 and / or the male fitting 180.

[0032] The spring 138 is disposed between the thumb plate 132 of the latch mechanism 130 and the female housing 120. The latch mechanism 130 is movable laterally with respect to the longitudinal axis 111 between a latched position (as shown) and an unlatched position in which the thumb plate 132 (and the latch mechanism 130 as a whole) is moved laterally (i.e., downward in the context of FIG. 3) toward the longitudinal axis 111. The spring 138 biases the latch mechanism toward the latched position.

[0033] The latch mechanism 130 defines an opening 134. While the latch mechanism 130 is in the latched position (as shown), the center of the opening 134 is laterally offset from the longitudinal axis 111 and from the center of the first opening 122. Thus, in the latched position, the crescent-shaped portion 135 of the latch mechanism 130 is positioned within the region defined by the first opening 122 (see FIG. 2). While the latch mechanism 130 is in the unlatched position, the center of the opening 134 coincides with the longitudinal axis 111 and coincides with the center of the first opening 122. Accordingly, the crescent-shaped portion 135 is no longer within the region defined by the first opening 122 while the latch mechanism 130 is in the unlatched position. During connection of the female connector 110 and the male connector 180, due to the force from the insertion of the male connector 180, the latch mechanism 130 moves to its unlatched position, and then, when the male connector 180 is fully inserted into the female connector 110, the latch mechanism 130 returns to its latched position.

[0034] FIGS. 4 - 8 show the fluid connector module 140 isolated and can more particularly illustrate its structure. The fluid connector module 140 is a distinct self-contained component having utility for use with a variety of different housings or form factors (e.g., the female connector 110, the dual female fluid connector device 200 shown in FIGS. 9 - 11, and others). The fluid connector module 140 can also be thought of as a cartridge, a core, etc.

[0035] The fluid connection module 140 includes a module housing 142. In the illustrated embodiment, the module housing 142 is substantially cylindrical, although other shapes are possible. The module housing 142 defines a longitudinal axis 141 and an internal space 143.

[0036] The fluid connection module 140 also includes a valve rod 144 disposed within the internal space 143. The valve rod 144 includes a base 145 which is the first end of the valve rod 144 (also shown in FIGS. 15 - 17). The base 145 of the valve rod 144 is fixed to the inner wall of the module housing 142. The valve rod 144 extends longitudinally along the longitudinal axis 141 of the fluid connection module 140. Thus, the valve rod 144 is cantilevered from its attachment to the module housing 142 at its base 145.

[0037] The fluid connection module 140 also includes a valve sleeve 150 disposed within the internal space 143. The valve sleeve 150 (as also shown in FIGS. 12 - 14) defines an open central region 154, whereby the valve sleeve 150 is disposed around the valve rod 144. Accordingly, the valve sleeve 150 is disposed between the valve rod 144 and the module housing 142.

[0038] The valve sleeve 150 is movable longitudinally along the valve rod 144 between a closed position (shown) and an open position (shown in FIG. 26 when the valve sleeve 150 is moved to the right side of FIG. 7). While the valve sleeve 150 is in the closed position (as shown), the valve sleeve 150 blocks so that a potential fluid flow path through the fluid connection module 140 is not opened. In contrast, when the valve sleeve 150 is moved to its open position (e.g., as shown in FIG. 26), the fluid flow path is open through the fluid connection module 140 because the valve sleeve 150 does not completely block the fluid flow path. Thus, the valve sleeve 150 functions as a valve assembly together with the valve rod 144 and the module housing 142, operably opening and closing the fluid flow path through the fluid connection module 140 via the internal space 143 of the module housing 142.

[0039] The fluid coupling module 140 also includes a plurality of annular elastomeric seal members (or simply "seals"). The seals can be made of materials such as silicone, fluoroelastomer (FKM), ethylene propylene diene monomer (EPDM), thermoplastic elastomer (TPE), buna, buna-N, thermoplastic vulcanizate (TPV), thermosetting resin, etc., but are not limited thereto.

[0040] For example, the fluid coupling module 140 includes a first elastomeric seal 160 disposed between the valve stem 144 and the inner diameter of the valve sleeve 150 while the valve sleeve 150 is in the closed position (as shown). The first elastomeric seal 160 is disposed within an annular seal groove 147 defined by the head 146 of the valve stem (see also FIGS. 15 - 17). As the valve sleeve 150 moves toward its open position (see FIG. 26), the valve sleeve 150 moves so as not to contact the first elastomeric seal 160.

[0041] The fluid coupling module 140 also includes a second elastomeric seal 162 disposed between the outer diameter of the valve sleeve 150 and the inner diameter of the module housing 142, while the valve sleeve 150 is in the closed position (as shown). The second elastomeric seal 162 remains in a fixed position relative to the module housing 142 such that as the valve sleeve 150 moves toward its open position (see FIG. 26), the valve sleeve 150 moves so as not to contact the second elastomeric seal 162.

[0042] The fluid coupling module 140 also includes a third elastomeric seal 166 disposed within the module interior space 143. The third elastomeric seal 166 is adjacent to the distal end of the module housing 142 opposite the distal end of the module housing 142 to which the base 145 of the valve stem 144 is attached. When the fluid coupling module 140 is incorporated into the female coupling 110 (see, for example, FIG. 3), the third elastomeric seal 166 is disposed between the second elastomeric seal 162 and the first opening 122. The third elastomeric seal 166 is configured to seal against the end 184 of the male coupling 180 (see also FIG. 1) when the male coupling 180 is connected to the female coupling 110.

[0043] The fluid coupling module 140 also includes a fourth elastomeric seal 168 disposed around the outer end of the module housing 142. The fourth elastomeric seal 168 is disposed to abut the inner diameter of the female housing 120 when the fluid coupling module 140 is incorporated into the female coupling 110 (see, for example, FIG. 3). The fourth elastomeric seal 168 can also be disposed elsewhere to seal against the female housing 120 (for example, the fourth elastomeric seal 168 can be a face seal that abuts the female housing 120).

[0044] In some embodiments, an annular spacer 164 is disposed between the second elastomeric seal 162 and the third elastomeric seal 166. For example, the annular spacer 164 can be press-fitted into the inner diameter of the portion of the module housing 142 configured to receive the second elastomeric seal 162 and the third elastomeric seal 166.

[0045] In some embodiments, the inner diameter surface of the third elastomeric seal 166 is spaced from the valve sleeve 150 while the valve sleeve 150 is in the closed position, such that the third elastomeric seal 166 and the valve sleeve 150 never contact each other under any circumstances. In some embodiments, most of the inner diameter surface of the third elastomeric seal 166 is spaced from the valve sleeve 150 while the valve sleeve 150 is in the closed position.

[0046] The fluid coupling module 140 also includes a spring 170. The spring 170 is disposed between the base 145 of the valve stem 144 and the valve sleeve 150. Thus, the spring 170 biases the valve sleeve 150 toward its closed position.

[0047] As shown in the example of FIGS. 9-11, the fluid coupling module 140 is configured to be modularly incorporated into various types of fluid couplings having different form factors. In this example, a double female fluid coupling device 200 includes two of the fluid coupling modules 140 (i.e., a first fluid coupling module 140a and a second fluid coupling module 140b). Thus, it should be understood that the design of the fluid coupling module 140 facilitates the universal use of the fluid coupling module 140 as a component associated with many different types of fluid couplings.

[0048] FIGS. 12-14 show the valve sleeve 150 isolated so that its structure can be viewed in more detail. The valve sleeve 150 defines an open central region 154 in which the valve stem 144 is disposed. defined.

[0049] The outer diameter of the valve sleeve 150 includes a smaller outer diameter portion 151 and a larger outer diameter portion 152. The smaller outer diameter portion 151 seals against the second elastomeric seal 162 while the valve sleeve 150 is in its closed position (see FIGS. 3 and 7). The larger outer diameter portion 152 extends against the inner diameter of the module housing 142 as the valve sleeve 150 moves between its closed position (see FIGS. 3 and 7) and its open position (see FIG. 26).

[0050] The transition between the smaller outer diameter portion 151 and the larger outer diameter portion 152 abuts against the annular shoulder of the module housing 142 extending radially inward (see FIGS. 3 and 7). The mechanical interference between the transition portion (between the smaller outer diameter portion 151 and the larger outer diameter portion 152) and the annular shoulder of the module housing 142 defines the closed position of the valve sleeve 150 and prevents the valve sleeve 150 from moving far from the base 145 of the valve rod 144 in response to the force from the spring 170.

[0051] The inner diameter of the valve sleeve 150 includes a smaller inner diameter portion 155 and a larger inner diameter portion 156. The smaller inner diameter portion 155 seals against the first elastomeric seal 160 while the valve sleeve 150 is in its closed position (see FIGS. 3 and 7). The larger inner diameter portion 156 defines a pocket for the tip of the spring 170, and the tip coil of the spring 170 abuts against the transition between the smaller inner diameter portion 155 and the larger inner diameter portion 156.

[0052] FIGS. 15 to 17 show the valve rod 144 separated, allowing a more detailed view of its structure. The valve rod 144 includes a base 145 at one end of the valve rod 144 and a head 146 at the opposite end of the valve rod 144. The grooved shaft 148 of the valve rod 144 extends between and interconnects the base 145 and the head 146.

[0053] The base 145 is attached to the module housing 142 at the second end 1422 of the module housing 142 (e.g., FIG. 7). The valve rod 144 extends along the longitudinal axis 141 of the module housing 142 towards the first tip 1421 of the module housing 142. The first end 1421 of the module housing 142 and the second end 1422 of the module housing 142 are the open ends at both ends of the module housing 142 that lead to the module internal space 143.

[0054] The base 145 defines one or more openings that fluidly connect the second end 1422 of the module housing 142 to the module interior space 143. In other words, the base 145 does not completely close off the module interior space 143 from the space outside the module housing 142. In the illustrated embodiment of the valve stem 144, the base 145 defines four openings, each formed as a quarter circle. The four openings 149a, 149b, 149c, and 149d are best shown in FIGS. 5 and 8.

[0055] FIGS. 18 - 20 show the female housing 120 in a separated state so that its structure can be seen in more detail. Here, the female housing 120 is shown without its terminal end 112. The female housing 120 defines a first opening 122 that leads to a fitting interior space 123 defined within the female housing 120. In an embodiment of the female fitting 110, a fluid fitting module 140 is disposed within the fitting interior space 123 (as shown, for example, in FIGS. 3, 7, and 26).

[0056] In the illustrated embodiment, the female housing 120 defines a lateral slot 125 that movably receives a plate portion of the latch mechanism 130 that defines an opening 134 (see, for example, FIG. 3).

[0057] In the illustrated embodiment, the female housing 120 includes a shroud 124 that rides on the thumb plate 132 of the latch mechanism 130 (as shown, for example, in FIGS. 3 and 24). In the illustrated embodiment, the top of the shroud 124 is slightly recessed so that the thumb plate 132 helps prevent an inadvertent depression in the latch mechanism 130 that could result in an unintended connection between the female fitting 110 and the male fitting 180. The shroud 124 is an optional feature.

[0058] The inner diameter wall of the inner portion of the first opening 122 defines a series of longitudinally extending slots 126 (as seen, for example, in FIGS. 3 and 20).

[0059] Figures 21 to 23 show the male joint 180 separated so that its structure can be seen in more detail. The male joint 180 includes a male housing 185 that defines an internal space 186 and a longitudinal axis 181. The male joint 180 includes a terminal end 182 that defines an opening 183 that communicates with the internal space 186. The male joint 180 also includes an end portion 184 (which is part of the male housing 185).

[0060] The male joint 180 also includes a male joint valve member 187 movably disposed within the internal space 186 of the male housing 185. The male joint valve member 187 includes a seal 188 that fluidly seals an opening defined by the end portion 184 from the internal space 186. The male joint valve member 187 within the internal space 186 is slidable relative to the male housing 185 along the longitudinal axis 181 of the male housing 185 between (i) an open position in which a first open end of the male housing 185 defined by the end portion 184 is fluidly connected to the opening 183 through the internal space 186 of the male housing 185, and (ii) a closed position (as shown in Figure 23) in which the male joint valve member 187 (and its seal 188) fluidly blocks the first open end of the male housing 185 defined by the end portion 184 from being fluidly connected to the opening 183.

[0061] The male joint 180 also includes a spring 190 disposed within the internal space 186, and this spring is arranged to bias the male joint valve member 187 toward its closed position. By connecting the male joint 180 to the female joint 110, the spring 190 is compressed and the male joint valve member 187 moves from its closed position to its open position.

[0062] Figs. 24 to 26 show a fluid joint assembly 100 with a connected configuration. That is, the female joint 110 and the male joint 180 are connected to each other, and their respective valves are open. Accordingly, the open fluid flow path 101 is established through the entire fluid joint assembly 100. The open fluid flow path 101 extends between (i) an opening 113 defined by the terminal portion 112 of the female joint 110 and (ii) an opening 183 defined by the terminal portion 182 of the male joint 180. The open fluid flow path 101 passes through the internal space 143 defined by the fluid joint module 140 within the female joint 110 and through the internal space 186 defined by the male housing 185 of the male joint 180.

[0063] The valves of each of the female joint 110 and the male joint 180 are moved to their open positions. For example, when the female joint 110 and the male joint 180 are connected to each other, the front surface of the head 146 of the valve rod 144 of the fluid joint module 140 abuts against the front surface of the male joint valve member 187 so as to displace the male joint valve member 187 to its open position. Further, when the female joint 110 and the male joint 180 are connected to each other, the leading annular surface of the end portion 184 of the male joint 180 abuts against the annular front surface of the valve sleeve 150 of the fluid joint module 140 and displaces the valve sleeve 150 to its open position. Accordingly, by the physical action of connecting the female joint 110 and the male joint 180 together, their valves open and the open fluid flow path 101 is formed through the fluid joint assembly 100.

[0064] Conversely, when the female joint 110 and the male joint 180 are not connected to each other, the springs 170 and 190 push back the valve sleeve 150 and the male joint valve member 187 to the closed position. As a result, the female joint 110 and the male joint 180 of both joint halves are sealed, preventing fluid from leaking from the female joint 110 and the male joint 180. Further, in FIG. 26, it can also be seen that there is essentially no opening region between the female joint 110 and the male joint 180 of the fluid joint half for providing a volume space for fluid enclosure. Therefore, when the valve sleeve 150 and the male joint valve member 187 return to their closed positions and the female joint 110 and the male joint 180 of the fluid joint half are separated from each other, there will be zero or essentially zero spillage or leakage. Thus, when the female joint 110 and the male joint 180 of the fluid joint half are separated from each other, there is essentially no fluid spillage.

[0065] Referring to FIG. 27, to connect two fluid processing components to each other, a fluid processing component coupler 300 (or, more simply referred to hereinafter as "coupler 300") can be used. In some embodiments, the coupler 300 is a single thermoplastic member made by injection molding. In certain embodiments, the coupler 300 is a one-piece metal member made by machining, die casting, or metal injection molding. In some embodiments, the coupler 300 is assembled from a plurality of components.

[0066] As will be further described below, the coupler 300 can be used as part of the female and male connectors described herein. However, more generally, the coupler 300 can be used to connect two fluid processing components of any type, design, or function to each other. For example, a fluid processing assembly can include a first fluid processing component, a second fluid processing component, and the coupler 300. The coupler 300 can be used to attach the first and second fluid processing components to each other. In some cases, the coupler 300 can be used to attach a terminal component (e.g., a barb end, a threaded end, a sanitary fitting end, etc.) to a second fluid processing component such as a connector body, a tube, a housing, etc. without limitation. The coupler 300 can be used to connect two fluid processing components of any type, design, and / or function to each other.

[0067] The coupler 300 includes a peripheral member 310 that defines an opening 312 having a central axis 301. In the illustrated embodiment, the peripheral member 310 is an open cylindrical member having a circular cross-sectional shape. In some embodiments, the cross-sectional shape of the peripheral member 310 may be other shapes such as oval, rectangular, oblong, elliptical, square, triangular, polygonal, etc., but is not limited thereto.

[0068] A first series of restraint elements 320a and a second series of restraint elements 320b extend or project radially inwards from the inner wall of the peripheral member 310. For example, in the illustrated embodiment, the first series of restraint elements 320a includes four individual restraint elements 320a that are equally spaced from each other around the inner circumference of the peripheral member 310. Similarly, the second series of restraint elements 320b includes four individual restraint elements 320b that are equally spaced from each other inside the inner circumference of the peripheral member 310.

[0069] The restraining elements can have various configurations, but in the illustrated embodiment, the individual restraining elements of the first series 320a and the second series 320a are arcuate inclined portions or ratchet teeth. The tips (lower ends) of the cams or ratchet teeth are adjacent to the outer edge (rim) of the peripheral member 310. "Adjacent" means that the front end of the cam or ratchet tooth is exactly at the outer edge of the peripheral member 310 or is recessed from the outer edge of the peripheral member 310 by a short distance.

[0070] The height of the individual restraining elements (cams) increases along the direction from the outer edge of the peripheral member 310 adjacent to the restraining element towards the outer edge on the opposite side of the peripheral member 310. Thus, the coupler 300 is configured to allow fluid processing components to engage with each end of the coupler 300 and be snap - fastened. In this way, the coupler 300 can conveniently connect two fluid processing components.

[0071] In FIG. 27, it can be seen that there are gaps between the individual restraining elements of the first series 320a. Similarly, there are gaps between the individual restraining elements of the second series 320b. The individual restraining elements of the second series 320b are axially aligned (e.g., as viewed along the central axis 301) with the gaps between the individual restraining elements of the first series 320a. Similarly, the individual restraining elements of the first series 320a are axially aligned with the gaps between the individual restraining elements of the first series 320a. Thus, it can be said that each restraining element of the first series 320a is radially offset from each restraining element of the second series 320b, and each restraining element of the second series 320b is radially offset from each restraining element of the first series 320a.

[0072] In the illustrated exemplary coupler 300, each of the restraint elements of the first series of restraint elements 320a and the second series of restraint elements 320b extends at approximately 45° along an arc around the central axis 301. Additionally, each of the gaps between the first series of restraint elements 320a and the second series of restraint elements 320b extends at approximately 45° along an arc around the central axis 301. While maintaining the same basic structure, other configurations are possible. For example, in some embodiments, the first series of restraint elements 320a and the second series of restraint elements 320b and the gaps extend at approximately 60° along an arc around the central axis 301, or at approximately 90° along an arc around the central axis 301, or at approximately 36° along an arc around the central axis 301, or at approximately 30° along an arc around the central axis 301, or at approximately 20° along an arc around the central axis 301, but are not limited thereto.

[0073] Figure 28 shows an example of how the coupler 300 can be used to connect two fluid processing components. In this example, the housing 120 of the female fitting 110 (see, for example, FIG. 3 as described above) has been modified to use the coupler 300. Thus, in FIG. 28, the modified female fitting is referred to as female fitting 110' and the housing is referred to as (i) body housing 120a and (ii) end housing 120b. In this example, the end housing 120b includes a threaded end portion 112' as opposed to the threaded end portion 112' of the female fitting 110. Thus, this example shows how the coupler 300 can be readily used to facilitate different combinations of end portions in relation to the base design of the female fitting 110. This ability can thereby provide manufacturing efficiency and / or user convenience (e.g., by enabling the user to select an end portion of a desired style).

[0074] In the illustrated example, the body housing 120a and the terminal housing 120b are coupled (mechanically attached) by a coupler 300. To ensure a mechanical attachment, each of the body housing 120a and the terminal housing 120b defines one or more recesses that receive a first series of restraint elements 320a and a second series of restraint elements 320b. In some embodiments, one or more recesses defined by the body housing 120a and the terminal housing 120b are each an annular groove (continuously and completely circumferentially extending). The figure of the female connector 110’ shows two restraint elements of the coupler 300 engaged with the recess defined by the body housing 120a, but the restraint elements of the coupler 300 engaged with the recess defined by the terminal housing 120b are not shown. This is simply because this cross-sectional view happens to cut the restraint elements engaged with the recess defined by the body housing 120a, but does not cut the restraint elements engaged with the recess defined by the terminal housing 120b. Although not visible in this figure, there are actually restraint elements engaged with the recess defined by the terminal housing 120b.

[0075] In the illustrated embodiment, the coupler 300 allows relative rotation of the body housing 120a with respect to the terminal housing 120b. Alternatively, in some embodiments, the coupler 300 (and / or housings 120a - b) can be configured to prevent or limit such relative rotation. For example, in some embodiments, the coupler 300 can include one or more keying elements that engage one or more complementary structural elements of the body housing 120a and / or the terminal housing 120b to prevent or limit relative rotation. In another example, one or more restraint elements of the coupler 300 can be structurally different from other restraint elements of the same coupler 300, and such different restraint elements can be used to fit with one or more complementary structural elements (e.g., different types of recesses such as deeper ones) of the body housing 120a and / or the terminal housing 120b to prevent or limit relative rotation.

[0076] Figure 29 shows another example of how the coupler 300 can be used to couple two fluid handling components. In this example, the housing 185 of the male fitting 180 (see, e.g., FIG. 23 as described above) has been modified to use the coupler 300. Thus, in FIG. 29, the modified male fitting is referred to as male fitting 180', and the housing is referred to as (i) a body housing 185a and (ii) a terminal housing 185b. In this example, the terminal housing 185b includes a threaded end portion 182' as opposed to the threaded end portion 182 of the male fitting 180. Accordingly, this example shows how the coupler 300 can be easily used to facilitate combinations of different types of end portions in relation to the base design of the male fitting 180. This ability can thereby provide manufacturing efficiency and / or user convenience (e.g., by enabling the user to select an end portion of a desired style). Further, in some embodiments, the coupler 300 is reversible. Alternatively, in some embodiments the coupler is non-reversible.

[0077] In the illustrated example, the body housing 185a and the terminal housing 185b are connected (mechanically attached) by a coupler 300. To ensure a mechanical attachment, each of the body housing 185a and the terminal housing 185b defines one or more annular recesses that receive a first series of restraint elements 320a and a second series of restraint elements 320b. In some embodiments, the annular recesses defined by the body housing 185a and the terminal housing 185b are each an annular groove (continuously extending and extending completely circumferentially). The view of the male connector 180’ shows two restraint elements of the coupler 300 engaged with the recess defined by the body housing 185a, but the restraint elements of the coupler 300 engaged with the recess defined by the terminal housing 185b are not shown. This is simply because this cross-sectional view cuts through the restraint elements engaged with the recess defined by the body housing 185a, but does not cut through the restraint elements engaged with the recess defined by the terminal housing 185b. Although not visible in this figure, there are actually restraint elements engaged with the recess defined by the terminal housing 185b.

[0078] In the illustrated embodiment, the coupler 300 allows relative rotation of the body housing 185a with respect to the terminal housing 185b. Alternatively, in some embodiments, the coupler 300 (and / or housings 185a-b) can be configured to prevent or limit such relative rotation. For example, in some embodiments, the coupler 300 can include one or more keying elements that engage one or more complementary structural elements of the body housing 185a and / or the terminal housing 185b to prevent or limit relative rotation. In another example, one or more of the restraint elements of the coupler 300 can be structurally different from the other restraint elements, and the different restraint elements can be used to mate with one or more complementary structural elements of the body housing 185a and / or the terminal housing 185b (e.g., different types of recesses such as deeper ones) to prevent or limit relative rotation.
