A hydraulic connector assembly is particularly adapted for use in subsea well installations. The connector assembly includes a female support member and a male support member, each carrying a connector. Each connector has a bore through it and a check valve that opens when the connectors are brought together. A resilient metal seal ring located in the female connector provides primary sealing. Belleville washers are located between the male connector and its support member. The washers deflect, allowing the entire male connector to move downwardly as the support members are brought together to provide a force to maintain the connectors in contact with each other.

Subsea hydraulic coupling

A guided-float accumulator suitable for use with a hydraulic system for an oil well blowout preventer is provided with a wing shut-off valve. Radially inwardly directed outlet parts are aimed at the bottom of the valve wing to generate unbalanced reaction forces which oppose the bernoulli effect forces caused by rapid movement of fluid through the chamber of the shut-off valve, thus preventing premature closing of the valve.
