Abstract
A quick connect/disconnect coupling for carrying fluid under pressure includes cooperating body and stem coupling assemblies. The body coupling assembly includes an axially movable slide having a closed position engaging a body valve when the two coupling assemblies are disconnected, and having an open position spaced from the body valve when the two coupling assemblies are connected. Latch fingers attached to the slide cooperate with the stem coupling assembly for pulling the slide toward its closed position when the two coupling assemblies are disconnected. The body valve cooperable with the slide is mounted on one end portion of an elongated member having its opposite end portion threaded into a finned support member retained within the body between a shoulder and a snap ring. A poppet valve in the stem assembly has a hollow metal stamping forming a guide shaft received in a guide hole in an axially elongated guide sleeve on a finned guide member. A longitudinally movable sleeve cooperable with latch members has a button biased to a blocking position by a leaf type of spring for cooperation with an abutment to prevent movement of the sleeve, and the button is depressible to a cl…
