Abstract
An injection pump with a full-load stop, preferably electronically controlled, which is adjustable against the force of a prestressed spring as a result of the control exerted by an electromagnet with a controllable stroke and which, when there is no current in the magnet, is displaceable by means of the spring into its terminal position which determines a reduced full-load quantity. Thus the maximum injection quantity is reduced in accordance with operating conditions and with the operational status of the engine; by this means, environmentally safer and smoother engine operation is possible at all operating conditions. The injection pump is also capable of continuing to function if the electrical or electronic parts fail.
