ABSTRACT:
An electric-motor tubine-vane fuel pump that includes a housing having a fuel inlet and a fuel outlet, and an electric motor with a rotor responsive to application of electrical power for rotating within the housing. A pump mechanism includes a turbine impeller coupled to the rotor for corotation therewith and having a periphery with a circumferential array of pockets. An arcuate channel surrounds the impeller periphery, and is operatively coupled to the fuel inlet and outlet of the housing for delivering fuel under pressure to the outlet. The impeller periphery is formed by a continuous uninterrupted serpentine rib of uniform peripheral thickness that extends at an angle back and forth between opposed axial side edges of the impeller periphery circumferentially around the impeller forming identical truncated pyramidal pockets alternating with each other around the impeller periphery on opposite side edges of the impeller.
