Abstract
An aggregate for delivering fuel from a fuel supply tank to an internal combustion engine of a motor vehicle comprises an electric drive motor, on the output shaft of which an inner rotor, having teeth on the peripheral surface, is positioned, and a ring-shaped outer rotor surrounding the inner rotor and having inner teeth meshing with the teeth of the inner rotor to form a gear pump. Fuel-conveying vanes are provided on at least one rotor to form a regenerative-type pump. The regenerative-type pump is connected in series to the gear pump as seen in the direction of the fuel supply.
