摘要：PURPOSE:To suppress the generation of cavitation so as to improve reliability by forming the pump rotor side opening part of a suction port provided at a lower plate in such a way as to be extended toward the rotating direction downstream side of the pump rotor. CONSTITUTION:A lower plate placed on the other end side of a casing is provided with a fuel suction port 31A. The opening part 31B, on the pump rotor 18 side, of the suction port 31A is formed being extended toward the rotating direction downstream side of the pump rotor 18. Accordingly, when fuel is sucked into a pump housing 4 from the suction port 31A by the action of a pump, the fuel flows inside the opening part 31B toward the downstream side and flows in the same flow state into the pump housing 4. As a result, cavitation is not easily generated, and the generation of an ill-condition such as corrosion can be prevented.兔的三合
