Abstract
PURPOSE: To arrange so that a high pump pressure may be maintained even at time of low rotation by effecting a contact of the external circumferential surface of a cylindrical member provided at the center of a rotor with a sliding member and the pressing of the sliding member against a diametrical direction.
CONSTITUTION: If a rotor 22 rotated in an arrow direction, the external circumferential surface of a cylindrical member 34 provided at the center of the rotor 22 shifts in the direction of a discharge port 18, pressing a sliding member 28 against the internal circumferential surface of a cylindrical cavity 14. As a result, the volume of a pump chamber 30 expands, resulting in the suction of a liquid from a suction port 16 and the discharing of the said liquid from a discharge port 18. In addition, if a high-pressure liquid is supplied from the suction port 16 and is discharged from the discharge port 18, the rotor 22 rotates in an arrow direction and functions as a liquid-pressure motor. Under this constitution, the cylindrical member 34 always presses the sliding member 28 against the internal circumferential surface of the cylindrical cavity 14 by mechanical force, so that a pump pressure can be maintained at a high level even at time of low rotation.
