Hydraulic coupling with pressure-energized dovetail seal

摘要

An undersea hydraulic coupling having a radial pressure-energized seal with a dovetail interfit is disclosed. The seal has a pair of flexible sealing surfaces for sealing with the male and female coupling members, and a cavity therebetween that is exposed to fluid pressure in the coupling. The outer circumference of the seal has a dovetail interfit between inclined shoulders in the female member bore and on a seal retainer that holds the seal in the bore.
