Abstract

581,925. Fluid-pressure servomotorcontrol systems. RYDER, C., and METROPOLITAN VICKERS ELECTRICAL CO., Ltd. Dec. 21, 1942, No. 18159. [Class 135] A hydraulic servomotor control system of the kind in which the differential pressure acting on the power device is controlled by control and repeater valves coupled respectively with the control and with the power devices has both valves arranged to control the supply and exhaust of pressure liquid to and from both sides of a double-acting power device. As shown in the Figure, the control valve 1 and the repeater valve 2 each has a pair of lands having cylindrical central portions with truncated conical portions on each side of the cylindrical portion. Each valve has a central pressure inlet port connected by pipe 26, 27 with a pressure supply pipe. Control ports 8, 9 in the control valve and control ports 15, 16 in the valve 2 are connected by pipes 22, 24 with ports 20, 21 on the two sides of a piston 17. The valve 2 is coupled to the piston by a link 29, or suitable linkage, so that when the control valve is displaced from its central position the piston is moved to a corresponding position in which the valve 2 is moved to a position in which one land permits outflow, corresponding to the inflow at the valve 1, and the other land permits inflow to balance the outflow through the valve 1. The piston 17 may be coupled to a hydraulic valve controlling the pressure applied to a main hydraulic engine for moving a main movable object.
