Abstract (en)

[origin: DE19805777A1] The invention relates to a fuel delivery unit, comprising a regenerative pump and an electrical motor for driving said pump. The electrical motor has a stator winding, a permanent magnet (37) and a rotor (29). Said rotor (29) and a running wheel (16) of the regenerative pump form a single component at the periphery (35) of which the permanent magnet (37) is introduced by positive fitting. It is therefore possible to produce a particularly flat and virtually leak-free regenerative pump.
