Abstract

In actuating drives for throttle valves, it can happen that the throttle valve becomes stuck, for instance by freezing solid. In the control device proposed, even a throttle valve that has frozen relatively solidly in place can be shaken loose with a relatively weak actuating drive. The control device is suitable in particular for vehicles provided with a throttle type of internal combustion engine.
