Abstract
PURPOSE: To control contacting pressure of vane with cylinder chamber inner wall which is obtained by oil pressure and centrifugal force by controlling oil pressure which acts upon vane by discharging lubricant oil in cylinder chamber to outside of cylinder chamber by the pumping function of bearing part.
CONSTITUTION: Pumping function can be obtained as the rotor 7 rotates by the sliding motion of spiral oil feeding grooves 25 formed on outer peripheral of rotor 7 and inner peripheral of bearing hole 9 of front side block 5. Then, when rotating speed of rotor 7 increases, pumping efficiency is also increased so that lubrican oil in the slit 11 which holds vane 12 is sucked out and the lubricant oil to be discharged into the space 26 is increased. Contrary to this, lubricant oil in slit 11 is dicharged to outside of the cylinder chamber as centrifugal force of vane 12 increases, and contacting pressure of vane 12 and cylinder chamber inner wall can be controlled in the desired range.
