Abstract
An undersea hydraulic coupling member is disclosed having angled flow ports to prevent ingress of debris into the hydraulic lines, and having a bleed passage to allow trapped hydraulic fluid to bleed off when the coupling members are disconnected. The poppet valve in combination with the angled flow ports helps keep the hydraulic system clear of debris when the members are disconnected.
