特徴とするフユーエルポンプ。 The rotationally driven rotor changes the volume of a pump chamber formed between the rotor and the inner wall of the rotor housing, so that the fuel sucked in from the suction side space is discharged into the discharge side space, In a fuel pump equipped with a roller vane that is housed in a plurality of grooves provided in a surface and rotates while being pressed against an inner circumferential wall of a rotor housing, the relationship between the diameter of the roller vane and the width of the groove in the circumferential direction of the rotor is expressed as follows. A fuel pump characterized by being provided with a fuel passage which is set in a relationship such that circumferential movement is restricted to a predetermined amount, and which introduces a part of the fuel sucked from the suction side space into the inner bottom of the groove. .
