Abstract: A multi-coupling assembly includes a first female coupler and a second female coupler whereby the female couplers are independently operable. Rotation of a rotational lever moves one of the female couplers from the coupling position to the release position without affecting a connection state of the other of the female couplers. Such independent operation of the female couplers is achieved by rotating cams that are configured such that when one of the cams rotates to interact against its respective female coupler, the other of the cams does not act on its respective female coupler. Pressure relief valves are operated such that internal pressure within a female coupler is released prior to the female coupler reaching the release position during a disconnection operation of the male coupler, and prior to the female coupler reaching the coupling position during a connection operation of a male coupler.

Abstract: A coupling assembly includes a nipple component and a coupler component that are connectable to each other to form a fluid flow pathway through the coupling assembly. The nipple component includes a nipple body that defines a chamber that receives a first valve and a second valve that are moveable within the chamber, and the first valve and the second valve are spring biased against each other by a spring loaded plunger of the first valve, and a second valve spring that biases the second valve in the closed position. During a connection operation and/or a disconnection operation, a balance of forces including the spring bias, in combination with system pressure, maintains the second valve in a closed position, thereby isolating the fluid flow from an area of the chamber in which components of the first valve reside, including isolating an interface seal from fluid flow.

Abstract: A multi-coupling system includes a first multi-coupling component including a plurality of individual first fluid couplers, and a second multi-coupling component including a plurality of individual second fluid couplers. The second multi-coupling component includes a locking pin assembly that is attached to a handle assembly, the locking pin assembly including a locking pin that is moveable in an axial direction between an extended position and a retracted position; a housing that houses the plurality of individual second fluid couplers, the housing further including a locking pin hole; and an operating lever configured to manipulate the locking pin assembly. In a connected and locked state, the locking pin is in the extended position in which a shaft end of the locking pin is located in the locking pin hole, thereby preventing rotation of the handle assembly.

Abstract: A multi-coupling assembly includes a housing, and a first female coupler and a second female coupler that are housed within the housing. Each of the first female coupler and the second female coupler are moveable between a coupling position connectable to a respective male coupler to permit a flow of fluid through the multi-coupling assembly, and a release position in which the male coupler is releasable from a respective female coupler. A rotational lever has a handle portion that is external from the housing and a shaft portion that extends from the handle portion into the housing. Rotation of the rotational lever moves one of the female couplers from the coupling position to the release position without affecting a connection state of the other of the female couplers.

Abstract: A coupler that can be configured for easy insertion and removal from an unthreaded cavity within a manifold or other part. The coupler includes an axially movable lock member that also carries a valve member for sealing against a valve seat of a main coupler body. The coupler also has a plurality of radially flexible fingers spaced apart by slots, and a lock member has one or more stop portions that engage the fingers to prevent radial collapse of the fingers for retention of the coupler in the cavity in the part.
