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 clearance position for allowing movement of the sleeve.
A quick connect/disconnect coupling having a longitudinally movable sleeve for providing movement of latch means between latched and released positions, a stop button carried by said sleeve and having a blocking position cooperable with abutment means for preventing longitudinal movement of said sleeve, said button being depressible to a clearance position relative to said abutment means for allowing longitudinal movement of said sleeve, and leaf type spring means carried by said sleeve for normally biasing said button to said blocking position; and, wherein said sleeve has an opening in which said button is received and a slot longitudinally spaced from said opening, said leaf type spring means extending through said slot and having one portion underlying said button and an opposite portion extending along an inner surface of said sleeve on the opposite side of said slot from said opening.

The coupling as defined in claim 1 wherein said button includes hook means extending downwardly through said slot.
Claim 4
Dependent Claim
32 words
The coupling as defined in claim 2 wherein said hook means comprises a pair of laterally spaced hooks and said leaf type spring means extends between said hooks to underlie said button.
Claim 5
Dependent Claim
36 words
The coupling as defined in claim 1 wherein said leaf type spring means includes laterally extending wings engaging the inner surface of said sleeve adjacent said slot and on the opposite side thereof from said opening.
Claim 6
Dependent Claim
42 words
The coupling as defined in claim 1 wherein said button has a downwardly extending shoulder on the underside thereof adjacent the end portion thereof opposite from said slot, and said leaf type spring means having a terminal end portion engaging said shoulder.
Claim 7
Dependent Claim
20 words
