ABSTRACT:
A coupling for pressurized fluid medium circuits such as hydraulic or air wherein the coupling parts may be easily manually interconnected even though the fluid systems communicating with the parts are under high pressure. The coupling parts include self-sealing valves axially displaceable between open and closed positions and the valves include faces exposed to the pressurized medium, the faces being of substantially equal area and disposed in opposite directions such that the axial forces imposed on the valves by the pressurized medium are substantially counterbalanced. Such pressurized faces including elastomeric seals and valve seat shoulders.
