ABSTRACT:
A shutoff apparatus for distributor injection pumps in internal combustion engines is proposed. The apparatus may also be used as a means of overspeed protection, and under the effect of an electromagnetic pushing magnet it opens the high-pressure chamber of the injection pump in order to shut off the engine. The opening of the high-pressure chamber is effected without the use of a valve subjected to the injection pressure, by means of the axial displacement of a pressure-equalized annular cylinder, which causes a relief bore to come into coincidence with the high-pressure chamber. The displacement of the annular cylinder is effected under the pressing action of an electromagnet. The area of the high-pressure chamber located opposite the distributor piston is sealed off by a slidable plug, which is pre-stressed by spring force and is centered via the annular cylinder by the distributor piston. The actuation push rod of the electromagnet acts in the direction along this slidable plug and it may in part replace this element.
