Japanese Patent JPH0663546
Kind Code:
B2
Abstract:
PURPOSE:To prevent any cavitation by providing a small passage which makes operating fluid flow out from a delivery side chamber to a suction side chamber. CONSTITUTION:Many channels 19b are formed in the outer periphery surface 19a of a rotor 19 at equal intervals in periphery direction on a vane pump VP. Vanes 18, that can make slidable contact with the inner periphery surface 20d of a cam ring 20a, are fitted in said channels. Three pump chambers 36-38 and suction/delivery ports 22-27 are mutually connected through the first oil passage OL1 and the second oil passage OL2 respectively. Hereupon, orifices 18c are provided on respective vanes 18 as small passages, therefore oil flows through orifices 18c from a delivery side chamber to a suction side chamber following the movement of vanes 18 in pump chambers 36-38 due to the relative rotation of the rotor 19 to the cam ring 20a. Thereby, generation of any cavitation in a suction side chamber is prevented.
