Abstract

An actuator for heating, cooling and climatic valves in vehicles includes a gear housing, an electric motor placed therein, a reduction gear acted on by the turning moment of the electric motor, a drive shaft and a position determining device connected thereto. A slide carrier with teeth on its perimeter allows use of an adjusting tool to make adjustments to the position determining device. Other fixing areas are provided on the slide carrier and in the driven gear which make it possible to form lock the slide carrier to the driven gear by means of a rapidly hardening substance without damaging the gear.
