Abstract

PURPOSE: To prevent the generation of short pass between an inlet and an outlet of hydraulic fluid and to remove a sliding motion between the end surfaces of a vane and the inside surface of a cylinder by providing a partition plate larger than the radius of a vane to both ends of a rotor for a vane type drive unit.
CONSTITUTION: A partition plate 13 is installed on both ends of a rotor 11. The partition plate has a radius larger than the radius of a vane 12 corresponding to its largest projecting point at the locatin of both ends. A disk-shaped concave part 16 which stores the partition plate 13 is produced on the inside surface of a cylinder 15, which constitutes a cylinder 14. On the other hand, a seal liquid injection hole 20 is produced at the axial center of a rotor shaft 17. A liquid communicating hole 20 which connects a liquid injection hole 18 to vane grooves 19 of the rotor 11 is produced. A sealing liquid 21 is supplied from a liquid injection hole 18 so as to fill a clearance H1 between the side end surface of the vane 12 and the partition plate 13 with the sealing liquid 21. A clearance H2 between the end surface of the vane 12 and the surface of an inner periphery of a cylinder is supplied with a sealing liquid 22.
