Abstract
722,385. Fluid-pressure servomotor-control systems. CLAYTON DEWANDRE CO., Ltd. Oct. 7, 1953 [Oct. 21, 1952 ; Nov. 20, 1952], Nos. 26420/52 and 29380/52. Class 135. In a power-assisted steering mechanism for road vehicles, the power of the servomotor is transmitted hydraulically to the road wheels. As shown, the servomotor 1, Fig. 1, which may be operated by fluid pressure, e.g. compressed air, or vacuum, is controlled by a valve 7, such as described in Specification 560,144, actuated by the steering wheel of the vehicle. The servo piston 2 is formed with rams 9, 10 working in cylinders 11, 12 connected by pipes 16, 17 with a hydraulic jack 20, the piston of which is connected to the usual mechanism for operating the road wheels. In operation, movement of the servo piston to the right displaces liquid from the cylinder 12 to the left end of the jack cylinder which results in movement of the jack piston to the left and the displacement of liquid from the jack cylinder to the cylinder 11. The flow of liquid between the cylinders 11, 12 and the jack cylinder is controlled by non- return valves, each including a closure member 30, Fig. 3, pressed by a light spring 34 against a seat 33 and formed with external flutes 35 to permit free flow of liquid into the jack cylinder, and an orifice 31 which throttles the flow of liquid out of the jack cylinder and damps out shocks produced by the impact of the wheels on uneven ground. In a modification, the rams 9, 10 may be replaced by a piston connected to the servo piston and working in a cylinder extending from one end of the servo cylinder and connected by pipes with the opposite ends of the jack cylinder. Further, the servo may be of the diaphragm type.
