Abstract
A fuel injection pump is proposed in which the fuel metering during the intake stroke of the pump pistons of the fuel injection pump is effected via a pressure conduit, the cross section of which is controlled first by an electrically controlled switching valve and second by means of the control of a fuel supply opening of the pressure conduit by means of a control groove, which communicates with the pump work chamber and, as part of a distributor shaft, is guided in synchronism with rpm. By means of the oblique disposition of the control groove and the possibility of an electrically controlled longitudinal displacement of the distributor shaft, the angular position at which injection takes place can be embodied in an arbitrary manner in combination with a switching valve.
