    摘要： A unit for delivering fuel from a supply tank to the internal combustion engine of a motor vehicle in which an electrical drive motor, which is embodied as an axial field motor, drives an impeller of a feed pump, which is embodied as a peripheral feed pump. In order to embody the delivery unit as flat as possible in the axial direction of the impeller, the rotor part of the axial field motor is disposed on the impeller, which carries the blades and which revolves in a pump chamber, and is combined with this impeller into one common element. The rotor windings of the rotor part can be disposed either inside a circle constituted by the blades of the feed pump or on the impeller radially outside the blades; the permanent magnets of the axial field motor are accordingly disposed in the housing, opposite the rotor windings.
