A fuel injection pump is proposed in which the fuel supply quantity supplied to the injection location is determined by metering the quantity of fuel aspirated. The metering of the aspirated quantities is effected with the aid of at least one magnetic valve which is located in the fuel supply line leading to the fuel injection pump and with the aid of a control edge moved in synchronism with the rotation of the fuel injection pump, which controls the communication between the fuel supply line and the pump work chamber in series with the magnetic valve. The opening times of the two control locations are each longer than the maximum metering time, the overlapping time of the two control times determining the opening time of the communication between the fuel supply and the pump work chamber. The metering time is thus determined on the one hand by the switching time of the control edge moved in synchronism with the rpm and the other by a switching process of the magnetic valve.
