摘要： A fuel pump has substantially coaxial outer and inner pump chambers. An impeller has partition walls correspondingly to the inner pump chamber to define inner vane grooves. A rear surface is located at a rear side in a rotative direction of each inner vane groove. At least a radially inner side of the rear surface inclines rearward in the rotative direction from the radially inner side to a radially outer side. A first line connects a radially inner end of the rear surface with a radially outer end of the rear surface. A second line radially extends from the radially inner end of the rear surface. The first line and the second line therebetween define a backward tilt angle α2, which satisfies a relationship of 30°≦α2≦80°.

摘要： A bearing for a motorized fuel pump is made of a Cu—Ni based sintered alloy, composed of: 21 to 35% by mass of Ni, 5 to 12% by mass of Sn, 3 to 7% by mass of C, 0.1 to 0.8% by mass of P, and the balance of Cu and inevitable impurities. A matrix of the bearing is formed with pores with a porosity of 8 to 18%, and the P component is predominantly included at the grain boundary, and free graphite is distributed along the insides of open pores that are open to the surface and extending into the bearing. In this bearing, a Sn rich alloy layer containing equal to or more than 50% by mass of Sn is formed on the insides of the open pores and near openings of the open pores.
