Abstract
A coupling for connecting a pair of conduits in fluid communication includes an improved socket assembly having a body in which a valve member is movable axially between a closed position and an open position. The valve member is releasably held in the closed position by a plurality of locking elements which engage a recess in the valve member. When a plug is inserted into the socket assembly, the locking elements move out of engagement with the valve member and into engagement with the plug to hold it against axial movement relative to the socket assembly. In order to enable the socket assembly to be utilized with plugs of different sizes, the chamber in the valve member is provided with a cylindrical outer section having a relatively large diameter to engage a relatively large diameter leading end portion of a first plug and a relatively small diameter inner section to engage the smaller diameter and axially longer leading end portion of a second plug. A seal is located between the two sections of the valve member and is effective to sealingly engage both plugs. A second seal is provided in the socket body to sealingly engage the valve member when it is both in the open and closed positions to prevent fluid leakage around the valve. This second seal is disposed in a recess formed by walls of different sizes. Although both walls of the recess may be integrally formed with a socket body section, in one embodiment of the invention the downstream wall of the recess is formed by a flat annular washer which is clamped in place betwen threaded base and outer end sections of the socket body.
