Abstract
An actuator, preferably a linear actuator, a reversible motor which drives an adjustment element via a transmission. To increase the self-clocking ability of the actuator, the actuator is equipped with a coil spring which has its one end secured to a rotating element in the actuator so that the spring is carried along in the rotation on the cylindrical part, which is static in relation thereto. When the motor is turned off, and the load on the actuator tries to displace the adjustment element, the movement of the coil spring is blocked, and the coil spring is tightened around the cylindrical part.
