Abstract
A coupling assembly includes plug and socket assemblies which are formed entirely of metal to enable them to be used at relatively high temperatures. The plug assembly includes a plug valve assembly which is operable between a closed condition and an open condition. The socket assembly includes a socket body in which there is a chamber for receiving the plug assembly. A socket valve assembly is disposed in and is movable relative to the socket body. The socket valve assembly includes a valve body which is movable relative to the socket body and a valve member which is disposed in the valve body. A leading end portion of the plug assembly includes a surface which applies force against an inner end of the socket valve body to move the socket valve body relative to the socket body and to form a fluid tight seal between the plug assembly and the socket valve body. The plug and socket valve assemblies are operated to an open condition when the plug assembly is inserted into the socket assembly. A second embodiment of the invention includes a bellows which is resiliently deflected and axially compressed as plug and socket assemblies are interconnected.
