Title: Subsea hydraulic coupling. [Connector with valve closed until units are joined]

Abstract

This patent describes a hydraulic connector assembly of the type having first and second support members for carrying respectively a first connector and second connector which telescopingly mate to form a hydraulic connection. Each connector has an axial bore with a seat and a check valve member for movement between an open position when the connectors are in contact with each other, allowing hydraulic fluid flow, to a closed position when the connectors are apart from each other, blocking hydraulic fluid flow, the check valve members being urged into the closed position by spring means. The improvement described here comprises: metal seal means actuable by axial deflection and carried by one of the connectors for sealing the axial bores to each other; an external flange located on the first connector; the first connector having conduit means extending through a hole in the first support member and adapted to be connected to a hydraulic fluid line for the delivery of hydraulic fluid. The first connector and conduit means are moveable in unison with each other and with respect to the first support member; and bias means for urging the connectors together to maintain the seal means in axial deflection. The biasmore » means comprises frusto-conical washers encircling the conduit means between the flange and the first support member, so that when the support members are brought together, the first connector and the conduit means will move a slight distance relative to the first support member, deflecting the frusto-conical washers to apply a force to the connectors to maintain them tightly together.« less
