Abstract (en)
[origin: WO2006045686A1] The invention relates to a fuel pump for a motor vehicle, which is provided in the form of a side-channel pump and in which two partially ring-shaped channels (21, 22) that encircle concentrically to one another are interconnected by a connecting channel (29). Connections (33, 34) of the connecting channel (29) are placed upon the partially ring-shaped channels (21, 22) so that, at the nominal rotational speed of the fuel pump, the same pressure prevails. When the rotational speed falls below the nominal rotational speed, fuel exits from the radially outer partially ring-shaped channel (22) and enters the radially inner partially ring-shaped channel (21). This ensures a sufficient flow rate through the radially inner partially ring-shaped channel (21).
