Abstract (en)

[origin: DE19834121A1] In preart fuel supply systems comprising two series-connected fuel pumps, it was not satisfactorily possible, despite great efforts, to obtain a sufficiently precise control of the fuel quantity delivered by the second fuel pump. The inventive control valve (30) which is relatively small enables a very precise control of the fuel quantity delivered in the pressure line (14) by the second fuel pump (12). The fuel supply system is provided for an internal combustion engine of a vehicle.
