ABSTRACT:
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.
