ABSTRACT:
A hydraulic coupling having a pressure-equalizing valve in the female coupler body is disclosed. A passage extends between the central bore or receiving chamber and the external surface of the female member. A valve in the passage allows sea water to flow into the annulus during connection or disconnection of the male and female coupling members, thus equalizing the pressure and preventing implosion of seals during disconnection of the coupling members.
