Undersea hydraulic coupling with radial seals on probe

摘要

An undersea hydraulic coupling is disclosed having a male member with at least two radial seals around the outer circumference of the probe. The seals on the probe engage the receiving chamber and seal retainer of the female coupling member. When the seals retained in the female coupling member are worn or damaged, the seals on the male coupling member provide the primary sealing mechanism in the coupling. The coupling includes a normally closed poppet valve within each of the male female coupling members.
