ABSTRACT:
An underwater hydraulic connector utilizing a cylindrical male portion inserted into a cavity in a female portion. The male portion consists of a telescoping inner and outer housing with a plurality of resilient seals mounted within openings in the outer housing whereby if the seals are compressed they will extrude beyond the surface of the male portion and contact the interior surface of a female portion so as to provide a sealed passageway between a set of ports in the male and female portions. The extrusion of the seal is accomplished by means of a bar which compresses the seal when moved longitudinally with respect to the outer housing. The bar is mounted on the inner housing. Relative movement of the inner housing and bar with respect to the outer housing is controlled by means of a piston and cylinder assembly and compression of the resilient seals is assisted by the external water pressure acting upon the inner housing to force it into the outer housing.
