Claims

[Claims for Utility Model Registration] A fuel pump device with a built-in motor, comprising a motor and a fuel pump disposed coaxially within the same casing as the motor, the pump defining a pump chamber therein. a pump housing, and one pump rotor housed in the pump chamber, the pump rotor having at least one axial end face having a flow path between it and the pump housing at an outer peripheral portion thereof. a first plurality of vane grooves formed to define a separate flow path between the first plurality of vane grooves and the pump housing radially inwardly of the flow path; A fuel pump device with a built-in motor, characterized in that the fuel pump device has a vane groove, and each of the flow paths are connected in series via a communication path provided in the pump housing.
