Title: Improvements in or relating to valving mechanism and power steering mechanism incorporating such valving mechanism
IPC: B62D5/08
Filed: 1952-12-08
Abstract: 714,906. Fluid-pressure servomotor-control systems; interconnected valves. BORG-WARNER CORPORATION. Dec. 8, 1952 [Dec. 15, 1951], No. 31054/52. Class 135 A valve mechanism for controlling a hydraulically-actuated servomotor piston 23 comprises two passages 56 connected in parallel between pressure fluid ports 58 and exhaust ports 60, two spring-loaded control valves 39, 54 in each each pair of valves to the opposite sides of piston 23, and a valve actuator 36 which is so connected to the valves that, in the neutral position of the actuator, all valves are partially and passage with connections 25, 26 from between equally open whereas, when the actuator is moved in one direction or the other, the first valve in one passage and the second valve in the other are opened further to give an increased flow whereas the other two valves are permitted to move towards the closed position under the action of their loading springs. As shown, the actuator 36 is keyed to the rotary shaft of the steering column of a vehicle and the valve casing 29 is connected to a shaft rotated by the pitman arm, the latter being actuated by servomotor piston 23 and being connected to the vehicle steering wheels. The valve casing will thus follow-up the movement of the actuator 36 and re-centre the valves after each steering movement. Should the pressure-fluid supply fail, steering can still be effected from the steering column by allowing the actuator 36 to contact and move the casing 29 directly. The valves are constructed so as to be pressure balanced.
