Abstract
An underwater hydraulic pressure regulator includes an ambient pressure ronsive cylinder and a regulator cylinder which are each fitted with integrally coupled pistons. The ambient pressure cylinder, as the name implies, is opened to ambient pressure by suitable ducting. The ambient pressure works against a volume of low pressure gas on the other side of a piston contained in the ambient pressure cylinder which in turn displaces the piston within the regulator cylinder. The back of the regulator cylinder is in communication with a conventional gas accumulator such that the restortative force on the back face of the second piston is influenced by both the ambient pressure and the gas accumulator pressure.
