Undersea hydraulic coupling with pressure-energized seals

摘要

An undersea hydraulic coupling having a pair of flexible, pressure-energized seals is disclosed. The seals are configured to seal radially between the male and female members of the coupling so that hydraulic fluid does not leak from the annular space between the receiving chamber and outer surface of the male member. The coupling is pressure-balanced for fluid communication through mating radial passages and the annular space between the members.
