Abstract
1,157,578. Valve for hydraulic braking systems; Valves. GOODYEAR TIRE & RUBBER CO. 21 Nov., 1966, No. 52042/66. Headings F2F and F2V. [Also in Division G3] A pressure control valve 6 for hydraulic braking systems comprises a housing 15 having connected thereto a brake line 8, a pressure line 22 and a sump line 7. A power valve 17 is slidably mounted in the housing and has a null position in which all the lines are isolated from one another (Fig. 3, not shown). The valve 17 is movable in one direction to connect the brake line 8 and pressure line 22 and in the other direction to connect the brake line 8 and sump line 7. The movement is controlled by a spring-loaded pilot valve 16 which in turn is controlled by a solenoid 20 deriving its energy from an anti-skid device (Fig. 1, not shown). In the solenoid inoperative position fluid pressure passes from line 22 through a passage 31, filter 33, passage 34, chamber 35 and passage 28 to a first pressure chamber 30 to urge the valve 17 in the one direction. Pressure builds up in a chamber 25 and passes through a passage 40 in the valve 17 into a second pressure chamber 41 to balance the pressure acting on the valve and hence urge the valve back to its null position. On half actuation of the solenoid (Fig. 3, not shown), the valve 17 is in its null position and the pressure line is connected to the sump line through the pilot valve. With the solenoid fully actuated (Fig. 4, not shown), the pressure line is cut off from the pressure chamber 30 which is connected to the chamber 27 from which the sump line extends. Fluid from the chamber 30 enters chamber 27 and chamber 41 to urge the valve 17 in the direction to connect the brake line and the sump line. The ends of the pilot valve are maintained at the same pressure by a passage 38 which is also connected to the sump line.
