Abstract

580,177. Controlling variabledelivery pumps. LUCAS, Ltd., J., and IFIELD, R. J. July 12, 1943, No. 11284. [Class 135] The swash plate of a swash plate pump is adjusted by a piston working in a cylinder adapted to be connected either to the inlet or outlet of the pump or other regions of different fluid pressure by a spring-loaded valve responsive to the delivery pressure of the pump. As shown in the Figure, the pump comprises spring-loaded plungers c slidable in inclined bores in a rotor a by a swash plate e adjustably mounted on trunnions. The swash plate is urged towards the full stroke position by a plunger n acted on by a spring r and, if desired, by the pump outlet pressure and is moved in the opposite direction by a plunger p carrying a piston x. The chamber w behind the piston is alternately connected to the pump inlet or outlet by a spring-loaded piston valve y actuated by the pump outlet pressure.
