Abstract
539,935. Valves. AUTOMOTIVE PRODUCTS CO., Ltd.. THORNHILL, P. W., and SIMPSON. J. K. Feb. 26, 1940, No. 3556. [Class 135] The spring pressure tending to hold a relief valve closed is caused to exert a lesser force on the valve when the valve is open. As shown, a pump 13 delivers liquid through a pressure regulator having alternative paths leading respectively to an outlet pipe 17 communicating with an accumulator 18, a selector valve 20 controlling a sleeve unit 23, and a return pipe 15 leading to the pump reservoir 16, and to a second outlet pipe 25 leading into the return pipe 15. The relief valve 45 is urged to its closed position by a main spring 53, and also by an auxiliary spring 51 pressing on a piston 52 engaging the flange 43 of the valve, this piston being forced away from the valve flange by the liquid pressure when the valve is open, the liquid then passing round the valve and through ports 81 in the piston to the outlet 25. At low liquid pressures the valve is closed and the liquid flows past a conical head 46 on the valve forcing a sleeve 31 back, and so to the outlet 17.
