Actuator and waste gas reclaiming valve, wastegate or variable turbine geometry with an actuator

摘要

The actuator has a drive, a rotating thread element (18) and a translationally driven output element. The thread element has two areas of different inclination. The thread has an inclination flatter than in the other areas at the beginning. The rotational axis of the thread element is inclined with respect to the translational axis of the output element.
