Abstract

The fuel pump has a housing containing an electric motor for driving a rotor wheel contained in a pump housing (6) incorporating at least one pump channel (9) for cooperation with the rotor blades attached to the rotor wheel. A stripper (14) is provided within the pump housing between the pump channel outlet and the pump channel inlet, the stripper having a non-linear contour (15) at the pump channel inlet end.
