Abstract
PURPOSE: To obtain positioning of rotor in thrust direction and smooth rotating motion without needle bearing by hydraulic pressure generated in pressure receiving surface parts which are formed on both ends of rotor.
CONSTITUTION: Fan shaped pressure receiving concaves 13, on both ends of rotor 7, which are inclined toward the rotating direction are radially formed at the eaqual pitches from the shaft center. Then, by relative sliding motions of rotor 7 and front side block 5 and rear side block 6, dynamic pressure by lubricant oil is generated in pressure receiving concaves 13 to lubricate end surface of rotor 7, and at the same time, to position rotor in thrust direction in cylinder chamber to secure rotating clearance between both side blockes 5, 6 and rotor 7.
