摘要： PROBLEM TO BE SOLVED: To prevent pressure in a pump chamber from increasing at a smaller curve portion on a cam surface.
SOLUTION: A pump chamber, defined by neighboring vanes of a plurality of vanes that are slidably supported radially on a rotor and rotated in a manner to slidably be in contact with a cam surface formed on the inner circumference of a cam ring, takes in fluid from an intake port at the intake curve portion, pre-loads the fluid at the larger diameter curve portion with a pre-load gradient, discharges the fluid from a discharge port at the discharge curve portion and is communicated to an intake port after being blocked off the discharge port and the intake port at the smaller diameter curve portion. A preceding vane is moved along the lift portion where the distance from the rotation center of the rotor increases gradually when the pump chamber is blocked off the discharge port by a subsequent vane and blocked off the intake port by the preceding vane, which prevents deviations in size at the smaller diameter curve portion and increase in pressure within the pump chamber due to shift in the core of the cam ring against the center of the rotor rotation.
