ABSTRACT:
A self-sealing quick disconnect coupling for detachably connecting a pair of fluid conveying conduits to each other while either or both conduits are subject to high internal fluid pressure. The coupling includes a pair of body members each containing a normally closed valve wherein one of the body members is provided with a valve operating mechanism which permits the valve of each member to remain in its closed position during interconnection of the members. After interconnection of the body members, the valve operating mechanism then permits and assists the valve of each body member to move to its open position whereat the valves of both members are interlocked to one of the body members to prevent closing of either or both valves during fluid flow through the coupling in its connected state, particularly when surges of high fluid pressure occur.
