Fuel Supply Apparatus

Abstract: A fuel pump is formed of a pump base having a fuel suction port and a fuel discharge port, and an impeller applying pressure to fuel sucked in from the fuel suction port of the pump base by rotation and having multiple impeller vanes that send out the fuel from the fuel discharge port. Herein, let A be a point on the impeller vane that intersects first with the fuel discharge port of the pump base and B be a point that intersects last with the fuel discharge port of the pump base, C be a point in the fuel discharge port of the pump base that intersects first with the impeller vane and D be a point that intersects last with the impeller vane, and O be a rotation center of the impeller, then, a relation of an angle ?1 yielded between lines CA and OS and an angle ?2 yielded between lines OC and OD is expressed as: 01 + 02 360°/the number of vanes.
