Abstract
PURPOSE:To reduce the pulsation of pressure oil by leaking a part of discharging oil to a low pressure side when the pulsation of the discharged pressure oil rises. CONSTITUTION:A pump cartridge 8 includes a rotor 12, a cam ring 14, and vanes 16. Slits 12a in which the vanes 16 are fitted to slide in a radial direction are provided on the rotor 12 and a V-shaped groove 12b is formed between each of the slits 12a. A through hole 4c for connecting the sliding contact face 4b with the rotor to a suction passage 4a is formed on a rear body 4. Since the V-shaped grooves 12b are connected to the through hole 4c being timed with the fluctuation in the pulsation pressure accompanying the rotation of the rotor 12, oil in a pump chamber is leaked reducing fluctuation in the pulsation pressure.
