Abstract (en)

[origin: DE19752884A1] The invention relates to a fuel supply system comprising a feed pump (11) designed as a flow or side channel pump that has a pump chamber (14) formed in a housing (13), a rotor (16) arranged inside said chamber and an electric motor (12) driving said rotor (16). In order to achieve an extremely flat construction in an axial direction, the electric motor (13) has no brushes and its rotor is formed by the rotor (16) of the feed pump (11). Furthermore, the fuel can be fed radially to a blade of the rotor (16).
