Abstract
An rpm governor for fuel injection pumps of internal combustion engines, having a pivotable spring tensioning lever which is engaged by an rpm signal transducer counter to the force, acting as the guide variable, of a governor spring and on which a pivot shaft following up the adjusting movement of the tensioning lever, of a two-armed transmission lever is disposed. The transmission lever is articulated on a quantity control member and is pivoted via an electrical adjusting motor. The adjusting motor is triggered by an electrical control unit, which processes engine and environmental parameters and effects a correction of the injection quantity.
