Title: Improved hydraulic control system
Inventor: PUGH CYRIL ALPHONSO
IPC: F15B13/06
Filed: 1947-03-21
Abstract: 663,513. Hydraulic control systems ; fluid-pressure servomotor control systems ; interconnected valves. PLESSEY CO., Ltd. April 29, 1948 [March 21, 1947], No. 7775/47. Classes 69 (ii) and 135. Liquid is pumped through a hydraulic control system at low pressure and when a service is to be operated the flow is directed by closing a by-pass valve and opening an inlet valve of the selected service by means of a control lever which enables hydraulic liquid to be raised to a high pressure and supplied to the selected service through a non-return valve and a differential relief valve unit is operated automatically when the pressure of liquid reaches a predetermined value causing the hydraulic liquid to fall to a lower pressure so that the by-pass valve and inlet valve are relieved while the pressure in the service is maintained. Fig. 1 is a sectional elevation and Fig. 2 a plan, in part section, of a control valve, while Fig. 6 shows diagrammatically a hydraulic system containing the control valve. Liquid under pressure is supplied by a pump to an inlet 35 and by operation of a hand control lever 3 supported by a ball and socket 2 can be supplied to and exhausted from two services to be operated. The outlets to the services are shown at 49 and 149. When the lower part of the lever is moved to the left and it is at the side of a gate 5 in which it is shown (Fig. 6) it acts on rods 7, 125 to open an inlet valve 11 and close a by-pass valve 126. Liquid under pressure thus passes to a service past a non-return valve 44. To release the pressure applied to the service the lever 3 is rocked in the opposite direction and controls a rod 9 which opens a servo valve 15 by first unseating a ball 23 and allows pressure from the conduit 19 to escape to exhaust. The valve 15 moves back in the bore of the valve body 17 following movement of the ball valve 23. When the pressure is applied to the service a rod 33 is moved to the left by liquid pressure to hold the lever 3 in its actuated position. When the service has been operated the pressure rises at the pump outlet and a relief valve 36 is raised. The operation in principle is the same for both services so that operation of one only has been described.
