Detailed Description
[0036] The present disclosure relates to a low-spill coupling assembly including a female coupling device and a male coupling device. Additional details are provided below.
[0037] Referring now to FIGS. 1-4 , an example female coupling device 100 is shown.
[0038] The female coupling device 100 includes a main body 110 having a front face 112. The front face 112 defines an opening 114 leading into a fluid passageway 122.
[0039] The female coupling device 100 also includes a termination 118 coupled to the main body 110 using known techniques, such as sonic welding, staking, press-fitting, and threading. The termination 118 is configured to be coupled to another component, such as a fluid line or device.
[0040] The example female coupling device 100 includes a stem 130, sleeve 136, and spring 124 positioned within the fluid passageway 122.
[0041] The stem 130 includes a base end 132 positioned against the termination 116. The stem 130 also includes a stem head 134 positioned within the sleeve 136. The spring 124 is positioned about the stem 130 and biases the sleeve 136 into the closed position shown in FIG. 4 . In this position, a shoulder 182 on the sleeve 136 engages a surface 184 formed by the main body 110 to limit further travel of the sleeve 136 in a direction toward the front face 112.
[0042] In this position, a first seal 142 provides a seal between the main body 110 and the sleeve 136. In addition, a second seal 144 provides a seal between the sleeve 136 and the stem head 134. These seals limit movement of fluid through the fluid passageway 122.
[0043] A further third seal 146 is positioned at the opening 114 of the main body 110 to seal against a mating male coupling device 200, described below.
[0044] Referring now to FIGS. 5-8 , the male coupling device 200 is shown.
[0045] The male coupling device 200 includes a main body 210 having a front face 212. The front face 212 defines an opening 214 leading into a fluid passageway 222.
[0046] The male coupling device 200 also includes a termination 218 coupled to the main body 210 using known techniques, such as sonic welding or staking The termination 218 is configured to be coupled to another component, such as a fluid line.
[0047] The example male coupling device 200 includes a valve member 230 and spring 224 positioned within the fluid passageway 222. The spring 224 is biases the valve member 230 into the closed position shown in FIG. 8 . A front surface 232 of the valve member 230 is exposed at the front face 212 of the main body 210. In this position, a shoulder 282 on the valve member 230 engages a surface 284 formed by the main body 210 to limit further travel of the valve member 230 in a direction toward the front face 212.
[0048] In this position, a first seal 242 provides a seal between the main body 210 and the valve member 230. The seal limits movement of fluid through the fluid passageway 222.
[0049] Referring now to FIGS. 9-10 , the female coupling device 100 and the male coupling device 200 are shown in a pre-coupled position. In this position, the main body 210 of the male coupling device 200 is partially inserted into the opening 114 of the main body 110 of the female coupling device 100.
[0050] In this position, the front surface 232 of the valve member 230 engages the stem head 134. In addition, the front face 212 engages the sleeve 136. Further, the third seal 146 seals against the main body 210 of the male coupling device 200 so that a fluid-tight configuration is created.
[0051] Referring now to FIGS. 11-12 , the female coupling device 100 and the male coupling device 200 are shown in a partially-coupled position. In this position, the main body 210 of the male coupling device 200 is more-completely inserted into the opening 114 of the main body 110 of the female coupling device 100.
[0052] As this occurs, the main body 210 of the male coupling device 200 is positioned in the fluid passageway 122 so that both seals 142, 146 engage the main body 210. Further, both the sleeve 136 and the valve member 230 are displaced against the springs 124, 224, respectively. When this occurs, the seals 144, 242 are disengaged so that fluid can start to flow through the fluid passageways 122, 222.
[0053] Referring now to FIGS. 13-14 , the female coupling device 100 and the male coupling device 200 are shown in a fully-coupled position. In this position, the main body 210 of the male coupling device 200 is completely inserted into the opening 114 of the main body 110 of the female coupling device 100.
[0054] Both of the springs 124, 224 are compressed, and the sleeve 136 and valve member 230 are further displaced. This assures that seals 144, 242 are fully disengaged so that fluid can pass through the fluid passageways 122, 222.
[0055] To release, the male coupling device 200 is pulled out of the female coupling device 100. When this occurs, the springs 124, 224 return the sleeve 136 and the valve member 230 to the resting positions shown in FIGS. 9-10 .
[0056] Referring now to FIGS. 15-18 , another example female coupling device 300 is shown.
[0057] The female coupling device 300 includes a main body 310 having a front face 312 and a maximum circumferential surface 313. The front face 312 defines an opening 314 leading into a fluid passageway 322 (see FIG. 18 ).
[0058] The female coupling device 300 also includes a termination 318 coupled to the main body 310 using known techniques, such as sonic welding, staking, press-fitting, and threading. The termination 318 is configured to be coupled to another component, such as a fluid line or device. The female coupling device 300 includes a locking collar, herein referred to as a quick connecting/disconnecting clip member 316, which is used to quickly disconnect and connect the female coupling device 300 with another component.
[0059] The example female coupling device 300 includes a stem 330, sleeve 336, and spring 324 positioned within the fluid passageway 322. The stem 330 includes a base end 332 positioned against the termination 318. The stem 330 also includes a stem head 334 positioned within the sleeve 336. The spring 324 is positioned about the stem 330 and biases the sleeve 336 into the closed position shown in FIG. 18 . In this position, a shoulder 382 on the sleeve 336 engages a surface 384 formed by the main body 310 to limit further travel of the sleeve 336 in a direction toward the front face 312. In this position, a first seal 342 provides a seal between the main body 310 and the sleeve 336. In addition, a second seal 344 provides a seal between the sleeve 336 and the stem head 334. These seals limit movement of fluid through the fluid passageway 322. A further third seal 346 is positioned at the opening 314 of the main body 310 to seal against a mating male coupling device 400, as described below.
[0060] In the depicted example, the clip member 316 includes a tab portion 320 and a plate portion 326 interconnected to each other at roughly a right angle in a generally L-shaped configuration. In FIG. 15 , the clip member 316 is in a resting or locking position. The clip member 316 can be biased or forced into the locked position using an integral cantilever or spring 328 (see FIG. 18 ). The clip member 316 is moved in a direction A within an opening 338 of the main body 310 to an unlocked position. The clip member 316 can be moved to this position to, for example, connect or release another component, such as, an insert.
[0061] The tab portion 320 of the clip member 316 provides a surface for the user to press down on the clip member 316 so as to place the clip member 316 in the uncoupled position when inserting the mating male coupling device 400. In some examples, it is not necessary to manually force down on the clip member 316 when inserting the mating male coupling device 400 as the mating male coupling device 400 upon engagement with an inner lip 348 (see FIG. 15 ) of the plate portion 326 will force the clip member 316 down into the uncoupled position. The plate portion 326 defines an aperture 350 (see FIG. 18 ) sufficiently large to allow the mating male coupling device 400 to extend partially therethrough and is generally alignable with the fluid passageway 322 of the female coupling device 300. The plate portion 326 slides in a slot 352 extending transversely of the female coupling device 300.
[0062] In one example, side surfaces of the female coupling device 300 can include a shoulder portion and the plate portion 326 of the clip member 316 can include barbed projections along its side edge. The barbed projections can have a substantially flat portion for engaging the shoulder portion of the female coupling device 300 so as to prevent the clip member 316 from being inadvertently removed from the female coupling device 300 after it has been inserted. This assures that the clip member 316 will remain with the female coupling device 300 at all times in typical use.
[0063] Referring now to FIGS. 19-22 , the male coupling device 400 is shown.
[0064] The male coupling device 400 includes a main body 410 having a front face 412. The front face 412 defines an opening 414 leading into a fluid passageway 422 (see FIG. 22 ).
[0065] The male coupling device 400 also includes a termination 418 coupled to the main body 410 using known techniques, such as sonic welding or staking The termination 418 is configured to be coupled to another component, such as a fluid line.
[0066] The example male coupling device 400 includes a valve member 430 and spring 424 positioned within the fluid passageway 422. The spring 424 biases the valve member 430 into the closed position shown in FIG. 22 . A front surface 432 of the valve member 430 is exposed at the front face 412 of the main body 410. In this position, a shoulder 482 on the valve member 430 engages a surface 484 formed by the main body 410 to limit further travel of the valve member 430 in a direction toward the front face 412.
[0067] In this position, a first seal 442 (e.g., major seal) provides a seal between the main body 410 and the valve member 430. The seal limits movement of fluid through the fluid passageway 422.
[0068] Referring now to FIGS. 23-24 , the female coupling device 300 and the male coupling device 400 are shown in a pre-coupled position. In this position, the main body 410 of the male coupling device 400 is partially inserted into the opening 314 of the main body 310 of the female coupling device 300.
[0069] In this position, the front surface 432 of the valve member 430 engages the stem head 334. In addition, the front face 432 engages the sleeve 336. Further, the third seal 346 seals against the main body 410 of the male coupling device 400 so that a fluid-tight configuration is created.
[0070] Referring now to FIGS. 25-26 , the female coupling device 300 and the male coupling device 400 are shown in a partially-coupled position. In this position, the main body 410 of the male coupling device 400 is more-completely inserted into the opening 314 of the main body 310 of the female coupling device 300.
[0071] As this occurs, the main body 410 of the male coupling device 400 is positioned in the fluid passageway 322 so that both seals 342, 346 engage the main body 410. Further, both the sleeve 336 and the valve member 430 are displaced against the springs 324, 424, respectively. When this occurs, the seals 344, 442 are disengaged so that fluid can start to flow through the fluid passageways 322, 422.
[0072] Referring now to FIGS. 27-28 , the female coupling device 300 and the male coupling device 400 are shown in a fully-coupled position. In this position, the main body 410 of the male coupling device 400 is completely inserted into the opening 314 of the main body 310 of the female coupling device 300.
[0073] Both of the springs 324, 424 are compressed, and the sleeve 336 and valve member 430 are further displaced. This assures that seals 344, 442 are fully disengaged so that fluid can pass through the fluid passageways 322, 422.
[0074] To release, the male coupling device 400 is pulled out of the female coupling device 300. When this occurs, the springs 324, 424 return the sleeve 336 and the valve member 430 to the resting positions shown in FIGS. 23-24 .
[0075] In certain examples, the spring 328 (e.g., resilient biasing member) is disposed below the tab portion 320. Upon pressing down on the clip member 316, the spring 328 is displaced from its at rest position to a displaced position. The clip member 316 is then biased upwardly such that the plate portion 326 rests in a circumferential groove 434 of the male coupling device 400 when in the coupled position. In other words, the clip member 316 is biased upwardly such that when the circumferential groove 434 of the male coupling device 400 is aligned with the inner lip 348 of the plate portion 326 of the clip member 316, the spring 328 will force the clip member 316 upward into engagement with the circumferential groove 434 thereby placing the clip member 316 into the coupled position and retaining the male and female coupling devices 300, 400 in a coupled state upon the application of the fluid pressure.
[0076] In other examples, by merely inserting the male coupling device 400, the clip member 316 will be forced down into its uncoupled position thereby doing away with the need for the user to press down on the tab portion 320 of the clip member 316. To uncouple the coupling the user simply presses down on the clip member 16 and removes the male coupling device 400.
