Abstract
A fuel injection system for internal combustion engines, which has a fuel injection pump and an additional device for varying the injection quantity pumped to the injection nozzle from a pump work chamber; the additional device has a blocking piston acted upon from the pump work chamber, the deflection stroke of which is controlled by an electrically controlled valve by means of which the injection duration or the injection quantity can be controlled. The operative face on the blocking piston facing the pump work chamber is smaller than the face facing the control valve and the control valve is embodied as an ON/OFF valve.
