ABSTRACT:
A connector for high pressure fluid conduits, such as fire hoses, has a chamber (10) with an inlet (4) and outlet (6) and between them a resilient ring (18), having an outer diameter close to the width of the chamber, on a dished support (14). The ring has a generally rectangular section except for a chamfer (24) on the inner upstream edge. The support has a central flow passage (16) aligned with the central passage (20) in the ring and carries two intersecting trapezoidal fins (22) projecting through the ring. When connected to a complementary coupling, the inlet and outlet bores of the connector correspond to the diameter of the chamfered portion of the ring. The device controls transient pressure peaks by deformation of the resilient ring without excessive reduction in flow.
