Abstract
A control arrangement for an injection pump of an internal combustion engine wherein a correcting element, determining the required power of the internal combustion engine, and a centrifugal speed governor, for maintaining the limiting speeds of the internal combustion engine, are effective on a control rod of the injection pump to adjust the required feed rate of the pump. A correcting displacement of the control rod is optionally limited by the control arrangement in dependence upon various influential variables of the internal combustion engine. The control arrangement includes an electromagnet which cooperates, under slight pretensioning, with a free end face of the control rod. An electronic circuit provided for processing an output signal of an inductive displacement pickup for the control rod position and signals defining the operating condition of the internal combustion engine to control a variable effecting a metered activation of the electromagnet.
