Patent number: 11435018Abstract: 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.Type: GrantFiled: April 22, 2019Date of Patent: September 6, 2022Assignee: Parker-Hannifin CorporationInventor: Brian K.
