ABSTRACT:
A quick disconnect coupling comprising a female coupling and a male coupling is provided with shrouding around the valves of the couplings. The female coupling includes a poppet slidably mounted within a shroud, and fluid can flow freely between the shroud and the poppet so that the poppet will close quickly when the couplings are disconnected. The male coupling includes a ball valve mounted within the shroud, and fluid can flow freely between the shroud and the ball so that the ball will close quickly when the couplings are disconnected. The elongated parts of the poppet of the female coupling and the shroud of the male coupling are formed from deep drawn sheet metal.
