Abstract
PURPOSE:To promote the reduction of pulsation in the pressure of oil by forming a delivery cam surface in a cam of a cam ring long than a suction cam surface so as to perform a delivery stroke for a vane to slide on the delivery cam surface in the time being taken longer than to perform a suction stroke for the vane to slide on the suction cam surface. CONSTITUTION:A vane pump has a rotor 4 rotating in a cam ring 2, and this rotor 4 mounts vanes 6 to be fitted into slits 4a formed in plural parts in the radial direction. The vane pump, changing the volume of a pump chamber 10 partitioned between the neighboring vanes 6 in accordance with rotation of the rotor 4, performs suction of oil and its delivery. The cam ring 2 forms two sets of cam curves, combining small and large contour side intermediate cam surfaces C and D of almost the minimum and maximum volume in the pump chamber 10 and suction and delivery cam surfaces A and B gradually changing the volume as one set, in the symmetrical position. Here the cam ring 2 is set up so as to tilt the center line E of the cam surface D by the degree of theta0 deg. to the side of the cam surface A.
