Abstract: A coupling for liquid and gas applications has a valve cartridge loaded from a front end of the coupling. The valve cartridge includes a valve body, a valve member, and a valve spring. The valve member is within the valve body and the valve spring coaxially surrounds the valve member and is disposed between the valve body and the valve member. An aperture in the valve body allows the valve member to pass through the valve body. A stop ring is disposed between the valve cartridge and the front-end portion to secure the valve cartridge in the valve cavity. The valve cartridge is secured in a valve cavity of the coupling by the stop ring. The valve member includes a valve that is opened when a mating coupling is inserted into the coupling. The valve also operates to shut off the flow when the couplings are disconnected.

Abstract: A quick-action multi-port fluid coupling having a socket member and a plug member each housing a plurality of coupling devices arranged in a non-linear array. A cam arrangement is provided for axially drawing the plug member into the socket member in a leveraged manner so that the coupling devices can be connected under fluid pressure with relatively little manual force required. The coupling can also include an alignment arrangement that ensures that no contact occurs between the cooperative coupling devices until the coupling members are in proper alignment relative to each other.
