  • Pressure balanced undersea hydraulic coupling
    Patent number: 6202690
    Abstract: An undersea hydraulic coupling is pressure balanced to reduce forces tending to urge the coupling members apart during coupling or uncoupling. A seal retainer having an L-shaped fluid passage is used to provide fluid communication between the radial fluid passage in the male member and the longitudinal fluid passage in the female member of the coupling. The seal retainer holds one or more radial seals in the female member upon disengagement of the male coupling member.
