Title: Inlet configuration of a fuel pump.
Inventor: KOYAMA HIDEKI
IPC: F04D5/00
Filed: 1993-01-21
Abstract: A fuel pump (1 Fig. 1) includes a flow channel 33b facing the outer periphery of an impeller (34). A suction port 33a opens into an inlet portion 33c which leads to an introduction groove 33d and a pressurizing groove 33e. The introduction groove 33d is formed so that its width gradually becomes smaller from the inlet portion 33c towards the pressurizing groove 33e. The deepest portion of the introduction groove 33d extends gradually outwards from the suction port 33a, and gradually becomes less deep in the direction of the groove 33e. With such a structure, the fuel sucked from the suction port 33a can flow smoothly so that the generation of fuel vapor is reduced and flow rate reduction of the fuel at high temperatures is prevented. <IMAGE>
