ABSTRACT:
A self-flushing subsea hydraulic coupling having a pair of interconnectable male and female and members and a flushing port for flushing the hydraulic line connected to one of the members. Each of the members includes a poppet valve, the poppet valve of the member not designated for flushing being sealed during the flushing operation. During the flushing operation, the male member is partially withdrawn from the female member receiving chamber so that its leading face passes the flushing port. Flushing fluid passes through the hydraulic line connected to the member, through the poppet valve, into the receiving chamber and out through the flushing port. An o-ring seals the receiving chamber and prevents sea water from entering the receiving chamber when the male member is partially withdrawn from the female member.
