摘要：A quick connect/disconnect coupling for carrying fluid under pressure includescooperating body and stem coupling assemblies. The body coupling assembly includesan axially movable slide having a closed position engaging a body valve when the twocoupling assemblies are disconnected, and having an open position spaced from the bodyvalve when the two coupling assemblies are connected. Latch fingers attached to theslide cooperate with the stem coupling assembly for pulling the slide toward its closedposition when the two coupling assemblies are disconnected. The body valve cooperablewith the slide is mounted on one end portion of an elongated member having itsopposite end portion threaded into a finned support member retained within the bodybetween a shoulder and a snap ring. A poppet valve in the stem assembly has a hollowmetal stamping forming a guide shaft received in a guide hole in an axially elongatedguide sleeve on a finned guide member. A longitudinally movable sleeve cooperable withlatch members has a button biased to a blocking position by a leaf type of spring forcooperation with an abutment to prevent movement of the sleeve, and the button isdepressible to a clearance position for allowing movement of the sleeve.
