Abstract
A self sealing fluid coupling utilizing separable interconnectable fittings wherein valve structure within one of the fittings simultaneously functions as the associated self sealing valve and as a pressure relief valve adapted to open and relieve excessive internal fluid pressure when the fitting is uncoupled. The combination self sealing and relief valve comprises an axially slidable sleeve including a radial surface exposed to internal fluid pressures for producing axial forces on the sleeve which are counteracted by a spring.
