ABSTRACT:
A fuel injection pump for internal combustion engines having an electrical shutoff device is proposed, in which an rpm limitation controlled in accordance with the supply pump pressure in the suction chamber is possible in the event that the failure of the rpm governor or of the annular slide disposed on the pump piston means that the pump work chamber can no longer be relieved in favor of the suction chamber. To this end, a control location dependent in the supply pump pressure in the suction chamber is provided, in the form of a relief slide valve, in a second relief line which leads from the pump work chamber to the suction chamber. The relief slide valve is subjected on one end to the supply pump pressure in the suction chamber and on the other end to the force of a compression spring, and upon the attainment of the maximum permissible rpm limit, the relief slide relieves the pump work chamber, thus automatically enabling a hydraulically controlled rpm limitation.
