Abstract

PURPOSE: To miniaturize bearings for a pump shaft, by providing surface seals over three portions between an inner peripheral wall of a cylinder and a circumference of a rotor so that radial load imposed on the rotor can be carried at surface seal parts.
CONSTITUTION: In a pump operation chamber B, a chamber moaving in the rotating direction of a vane 2 is decreased in volume with a rotation of the vane 2 and oil is discharged into housing discharge pressure chambers 8a and 9a from a discharge port 7. On the other hand, in the pump operation chamber B, a chamber in a rear side of rotation of the vane 2 is increased in volume and oil is sucked from a suction port 6a. In this time, since a cylindrical rotor 1 is in surface contact with an inner peripheral wall 3a of a cylinder at three portions, a radial load imposed on the cylindrical rotor 1 can be carried at the surface contact parts. Accordingly, bearings 14 and 15 for a pump shaft interconnecting with the cylindrical rotor 1 can be miniaturized.
