Abstract
A combination spherical swivel joint and quick disconnect coupling device for a fuel supply line or the like permits universal swiveling of a spherical member within a socket member while the members are connected together in flow communication, and has interconnectable means for uncoupling when an external tensile force above a predetermined limit is applied to the fuel line. Valving is disposed within the spherical member and within the socket member so that when the members uncouple the passageway within each member is closed. A retaining member positioned within the socket member maintains the coupling relationship during normal operation. In one embodiment the retaining member is secured to the socket member by a frangible shear pin, while in another embodiment the retaining member is attached to the socket member by a compressible annular spring positioned with an annular groove having a cam surface which permits the spring to be compressed and released from the groove when the tensile force exceeds the predetermined limit.
