Abstract

The pressure regulator is for a hydraulic accumulator which also acts as a safety valve to open itself at a pressure close to that of the system. This allows orifices to be dispensed with as well as an anti-return valve. A hollow sliding sleeve valve(10) has orifices(10) which communicate with the inlet(5) pressure when these orifices are opposite a neck (9). This sleeve valve moves to regulate the pressure in the accumulator to maintain a constant value. Play between the sleeve valve(10) and the sleeve(8) allows pressure in the accumulator to rise until a valve(19) opens to maintain the pressure slightly above the operating pressure. The valve acts as a pressure relief safety valve in the event of blockage of the sleeve valve.
