Abstract

See full text

A female undersea hydraulic coupling member is equipped with a plurality of pressure-energized metal seals configured to seal between the body of the female member and the probe of a corresponding male hydraulic coupling member in response to ambient hydrostatic pressure and/or hydraulic fluid pressure. Pressure-energized metal seals may also be provided to seal between the body of the female coupling member and a removable seal retainer or seal cartridge. In one particular preferred embodiment, the pressure-energized seals are back-to-back metal C-seals separated by annular seal supports having a generally T-shaped cross section and retained on one or more shoulders in the body of the female member by a removable seal cartridge.
