オイルポンプ。 A rotor that rotates around a point eccentric from the center of the rotor chamber is disposed in the rotor chamber, and is swingably held on the outer periphery of the rotor and elastically abuts on the inner circumferential surface of the rotor chamber. A plurality of vanes are provided that rotate together with each other, and the volume of the pump chamber formed between the vanes expands from the oil suction port, and then gradually decreases toward the oil discharge port, and the volume of the pump chamber is increased. A one-rotor oil pump, wherein the amount of deflection of the vane is set so that when the pressure exceeds a set pressure, the vane separates from an inner circumferential surface of the rotor chamber and the discharge pressure is regulated.
