Abstract
PURPOSE: To provide on the side surface of rotor a device for attaching the rotor close to a change-over valve plate with proper pressure such that excessive gap is not formed between the rotor and change-over valve in operation to prevent fluid from leakage.
CONSTITUTION: In the operation of pump, high pressure fluid flowing from a cylinder 7 to an actuator through passages 8, 16, 15 is introduced between a change- over valve plate 14 and a rotor 24 and produces force to separate one from another while high pressure fluid in the cylinder 7 flows into a pressure chamber 25, pressure pocket 30 and change-over pocked 32 through passages 26, 31 so that the fluid introduced into the pressure chamber 25 and the elasticity of elastic seal 27 attach the rotor 24 close to the change-over valve plate 14 to permit the pump operation without excessive leakage of fluid. Also fluid between the slide plate 28 and rotor 24 is positively prevented from leakage by the elastic seal 27.
