円周流ポンプ。 A pump chamber in a pump housing having an inlet and a discharge port is equipped with an impeller that is rotationally driven by an electric motor, and as the impeller rotates, the liquid sucked from the inlet is transferred between the front and back sides of the impeller. A circumference configured such that liquid is pumped to the discharge port through a pumping gap formed between the circumferential wall of the pump chamber and the outer circumferential wall of the impeller by the rotational force of a plurality of grooves formed on the periphery of the pump chamber. In the flow pump, a large diameter vapor vent hole is provided which communicates the pump chamber with the outside, and a small diameter vapor vent hole is provided which is a valve body that opens and closes the large diameter vapor vent hole and which communicates with the vapor vent hole when closed. A valve body formed with a hole is provided, and a valve body opening/closing means is provided which senses the fuel temperature and opens the valve body when the temperature is above a predetermined temperature and closes the valve body when the temperature is below a predetermined temperature. Circumferential flow pump featuring:
