ABSTRACT:
A female coupling includes an outer housing and a cartridge removably mounted in the housing. The cartridge includes a retainer sleeve which is stationary within the housing, a valve body and a spool attached to the valve body which are slidable axially within the housing, and a valve which is slidable axially within the valve body. A seal on the retainer sleeve seals a port in the spool when the female coupling is connected to a male coupling, and the spool is axially movable relative to the seal to relieve the internal pressure in the female coupling during connection and disconnection of the male coupling. A piston is slidably mounted within the valve body to assist in closing the valve during disconnection.
