ABSTRACT:
The invention relates to an actuating device for a throttle valve arranged in an intake pipe in a diesel internal combustion engine, having a mechanical adjusting linkage for the load-dependent adjustment of the throttle valve, the adjusting linkage having an idle path. In order to be able to control the throttle valve as a function of a plurality of operating parameters, an actuator actuated by an auxiliary force is proposed via which the throttle valve position predetermined as a function of load can be altered within the idle path.
