Abstract

589,381. Fluid-pressure servomotorcontrol systems. AUTOMOTIVE PRODUCTS CO., Ltd., and CHOUINGS, L. C. Dec. 4, 1944, No. 32617/45. Divided out of 589,359. [Class 135] A control valve applicable, e.g. to the hydraulic system of the steering gear described in Specification 589,359 and including a reservoir 10, pump 12, accumulator 9 and a servomotor 15, comprises a casing having main and auxiliary connections 23, 24 respectively, a servomotor connection 21 and an exhaust connection 25 and housing a fixed sleeve 28 and complementary valve members 30, 42 pressed together by springs 36, 50 and by the liquid pressure on the annular shoulder 48 on the member 42. The conical end 31 of the member 30 is pressed against the sleeve 28 by the spring 36. When movement to the right of the servomotor piston 16 is required, the member 42 is moved to the right by the lever 52, this permitting liquid to flow under the action of the pressure liquid in the cylinder space 18 from the cylinder space 19, through the pipe 20 and the bore 58 of the valve member 30 to the exhaust connection 25. Movement of the member 42 to the left moves the conical end of the member 30 away from the sleeve 28 and permits pressure liquid to pass from the connection 23 through the pipe 20 to the space 19 of the servomotor cylinder and this, acting on the larger area of the piston, moves it to the left.
