Abstract: A coupling assembly entirely formed from plastics material is provided for selectively connecting and disconnecting first and second fluid lines. A male coupling member includes an external groove that receives a radially inward extending shoulder of the sleeve. An external groove on a female coupling member is selectively engaged by latching tabs extending radially inward from the sleeve. The latching tabs are selectively pivoted radially outward through depression of release buttons. The pivoting action of the latching members is defined along a central portion in which circumferential strips undergo a twisting action. A ring may also be provided as an accessory to the coupling assembly for selectively maintaining the male and female members in coupled relation. The ring is adapted for movement between first and second positions. In the first position, movement of the latching tabs is prohibited by the ring. In the second position, the ring does not interfere with the movement of the latching tabs.

Abstract: A coupling comprises a hollow body with a valve supported therein to define an annular chamber for receiving a mating stem component. A slide sleeve is mounted for axial movement in the annular chamber to control flow past the valve. Carried on the slide sleeve is a wiper mounted for sliding movement and having an end face which generally fills the open end of the annular chamber. A pair of slide hooks act to engage the stem member and move the slide member to a closed position when the coupling is disconnected. The slide hooks extend through slots in the wiper and are held in engaged position in the slide sleeve by cooperating surfaces on the hooks and the wiper. A pair of opposed dog-type detent members are maintained in a radially outward position by the outer surface of the wiper when the coupling is disconnected.

Abstract: A quick connect/disconnect coupling for carrying fluid under pressure includes a latch mechanism requiring two independent movements in two different directions for releasing same. The coupling includes improved seals at various locations along with a slide bearing, and improved support fins for internal valves. The coupling is keyed in a plurality of different mating pairs of body and stem assemblies so that the stem assemblies having different keys cannot be mated together.

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.

Abstract: A poppet type valve assembly comprising a body having an axial bore extending therethrough and defining a fluid flow passage and an internal, generally cylindrical valve chamber. Seat means are carried in the bore adjacent a first end of the valve chamber to define a valve seat coaxial with the bore. A poppet valve member is mounted in the chamber for movement axially thereof toward and away from the seat. Extending axially of the chamber is a coil spring for maintaining the poppet valve member under a continual bias toward the seat. Valve stop means are provided for limiting movement of the poppet valve member in a direction away from the valve seat. The valve stop means including a central body portion having a plurality of legs which extend radially between a shoulder and the coil spring.
