ABSTRACT:
A quick connect fluid coupling having a female part and a male part which is insertable into the female part to thereby establish the fluid connection between the coupling parts. A metal spring retainer in the female part engages an outwardly extending flange on the male part upon insertion into the female part to lock the coupling parts together. In addition, a shut off valve member is contained within the female part and is movable between a closed position and an open position. In the closed position, a seal ring in the female part sealingly engages a central cylindrical portion of the valve member and blocks fluid flow through the female part. Conversely, upon insertion of the male part into the female part, the male part moves the valve member to its open position and enables fluid flow through the fluid coupling parts. Simultaneously, the seal ring engages the outer periphery of the male part and fluidly seals the male and female parts together.
