Abstract

589,095. Valves. AUTOMOTIVE PRODUCTS CO., Ltd., and SIMPSON, J. K. Feb. 12, 1945, Nos. 3486/45 and 418/46. [Class 135] A fluid regulating valve comprises broadly a casing having inlet and outlet ports and between them a spring-loaded valve plunger urged to the outlet opening position and subject on its opposite sides to the pressures at the ends of a restriction interposed in the flow path between the inlet and the outlet. In a hydraulic system including a reservoir 30, pump 31, main operated device 34, such as a servo-operated steering gear, and an accumulator 38 for operating other devices, the valve comprises a housing 10 having an inlet 18 and main and auxiliary outlets 23, 21 respectively communicating with housing grooves 22,20 the flow through which is controlled by a spring- loaded piston 13 having a bore 25 the pressure drop across which determines the position of the piston. On starting the pump, the pressure liquid flows through the bore and the groove 22 to the device 34 from which excess liquid returns to the pump inlet pipe 32. When the flow from the pump reaches a predetermined value, the piston is forced to the left and its end 24 restricts the flow through the groove 22. Continued movement to the left results in the opposite end 19 of the piston uncovering the groove 20 and permitting flow to the accumulator 38. After the accumulator has been fully charged, liquid passing the outlet 21 returns to the reservoir 30. Operation of the accumulator may increase the pressure to the right of the piston and, consequently, the flow through the bore 25. This results in the piston being moved further to the left and restricting the flow through the groove 22 so that the pressure to the left of the piston builds up until it counterbalances the pressure to the right and returns the piston to its original position. Interchangeable bushes having bores of different sizes may be inserted in the end of the piston. The valve may be incorporated in a system without an accumulator and in this case the. auxiliary outlet 21 is omitted.
