Coupling
A system includes a body with a fluid passage therethrough, a first open end, and an opposite termination, a valve positioned within the body and including first and second ends, the valve moving between open and closed positions, the valve being biased into the closed position, and a seal positioned on the second end of the valve, the seal forming the closed position when the valve is biased towards the first open end of the body, and the seal engaging a shoulder formed by the body to retain the valve within the body. The seal is accessible from the termination of the body to allow the valve to be coupled to the body.

This application claims the benefit of U.S. patent application Ser. No. 61/547,445 filed on Oct. 14, 2011, the entirety of which is hereby incorporated by reference.
BACKGROUNDQuick disconnect couplings are used in various applications to connect two lines to create a fluid pathway therethrough. The couplings typically include cooperating male and female couplings that form the connection. A latch is used to connect the male and female couplings. An example of such a coupling is shown in U.S. Pat. No. 5,104,158 filed on May 31, 1991, the entirety of which is hereby incorporated by reference.
Various components on the couplings can move to accomplish the connection therebetween. For example, a latch of the female coupling (or body) typically moves within the female coupling to connect the female coupling to the male coupling (or insert). Also, the male coupling is typically at least partially received within the female coupling to accomplish the connection.
SUMMARYAspects of the present disclosure relate to systems and methods for forming couplings. In one aspect, a female coupling includes a body defining a fluid pathway therethrough, and a slot extending transversely with respect to the fluid pathway, and a latch positioned in the slot to move between locked and unlocked positions. A mating male coupling defining a fluid pathway forms the complete coupling.
This application is directed to systems and methods for forming couplings.
In the example shown, the insert 120 is being coupled to the body 110 by a clip or latch 130. The body 110 and the insert 120 together form a fluid passage way therethrough. The latch 130 moves in a direction that is generally transverse to the longitudinal direction of the fluid pathway to couple the body 110 and the insert 120, as described further below.

The body 110 houses a valve 250 positioned therein. The valve 250 is biased by a spring 258 to a closed position as shown in

The insert 120 houses a valve 450 positioned therein. The valve 450 is biased by a spring 458 to a closed position as shown in

In this example, front portions 252, 452 of the valves 250, 450 form a “make before you break” connection, in that a seal 254 on the valve 250 and a seal 454 on the valve 450 are unseated after the valves 250, 450 are coupled so that there is little or no loss of any fluid flowing through the coupling 100 when the body 110 and the insert 120 are uncoupled.
When coupled as shown in
One possible advantage of forming the latch groove 530 in this manner is that there is additional material forming the insert 120 at the end 534 of the latch groove 530. This material can function to strengthen the insert 120 at this juncture and help resist breakage of the insert 120 at the latch groove 530.
Referring to
Next, for the body 110, the spring 258 is placed on the valve 250, and the valve 250 is introduced into the opening 230 formed in the body 110. The valve 250 is compressed in a direction X against the spring 258 until in the position shown in
Once the seal 254 is in position, the valve 250 can be released, allowing the spring 258 to force the valve 250 forward until the seal 254 engages a shoulder 244 formed in the termination 240. In this position, the seal 254 resists further forward biasing by the spring 258 so that the valve 250 is retained in the body 110. In addition, with the seal 254 engaging the shoulder 244, fluid flow through the body 110 is stopped.
The insert 120 is similarly assembled by forcing the valve 450 and the spring 458 through the insert 120 until a seal groove 472 is accessible through the termination portion 420. The seal 454 is then placed in the seal groove 472 to maintain the valve 450 within the insert 120 and to seal the insert 120 when the valve 450 is in the closed position.

In this example, the system 500 includes a container 510 that is sized to hold a fluid, such as gasoline or another fuel. In this example, the container 510 is used as a source of fuel for a boat or other vehicle. Other configurations are possible.
The container 510 includes a cap 512 that can be rotated to affix or remove the cap 512 from the container 510. The cap 512 can be removed to introduce additional fluid into the container 510. Once filled, the cap 512 is replaced to maintain the fluid in the container 510.
The container 510 also includes a vent 514 configured to maintain the interior of the container 510 at a given pressure. For example, the vent 514 can be configured to let fluid (e.g., air) into and/or out of the container 510 as necessary to compensate for removal of density from the container (e.g., make-up air) and/or the expansion and contraction of the fluids contained within the container 510.
The container 510 further includes a fluid supply module 516 with a base 520 that is coupled to the container 510. The fluid supply module 516 includes a fluid passage that extends from the base 520 to an opening 518. A hose barb extends into the container 510 (see, e.g., hose barb 621 in
The opening 518 is threaded to correspond with threads on the termination portion 420 of the insert 120. The insert 120 is screwed into the opening 518 to couple the insert 120 to the fluid supply module 516. Other mounting configurations are possible.
In this configuration, the insert 120 is in fluid communication with the fluid in the container 510. The valve 450 closes the insert 120 so that the fluid within the container 510 does not escape until the insert 120 is mated with the body 110.
The termination 240 of the body 110 is connected to tubing 532 that extends to a destination for the fluid, such as an engine of the boat. When the body 110 is connected to the insert 120, the valves 250, 450 are moved to their open positions, thereby allowing fluid to flow from the container 510, through the fluid supply module 516 and insert 120/body 110, and through the tubing 532 to a desired destination.
When the fluid within the container 510 is depleted, the body 110 can be disconnected from the insert 120 by actuating the latch 130 and removing the body 110 from the insert 120. The valves 250, 450 close as the body 110 is removed so that the flow of fluid through the body 110 and the insert 120 is stopped. Once disconnected, the container 510 can be removed and refilled, as needed.

The fluid supply module 616 also includes a termination 620 that is configured in a manner similar to that of the opening 518. The termination 620 is threaded to allow a legacy fluid line to be connected thereto. The termination 620 can be closed with a plug 622 that is threaded onto the termination 620 when not in use. In this manner, the fluid supply module 616 is configured to allow for backwards compatibility with existing infrastructure.

In one example, the first and second portions 715, 720 are coupled by a welding technique, such as by sonic welding, staking, adhesive, etc., or by insert molding or by pressing or a snap fit. The first and second portions 715, 720 can be made of different materials to accommodate different applications. For example, in one application, the first portion 715 is made of a polymeric material, and the second portion 720 is made of a metal material, such as brass. This allows for the second portion 720 to be more easily terminated for different applications and to be manufactured more cost-effectively. The different materials can also exhibit other benefits, such as added strength and allowance for molding of complete geometries, such as those exhibited by the body. Other configurations are possible.
Various modifications and alterations of this disclosure will become apparent to those skilled in the art without departing from the scope and spirit of this disclosure, and it should be understood that the inventive scope of this disclosure is not to be unduly limited to the illustrative embodiments set forth herein.
