ABSTRACT:
An actuator element suitable, for example, for actuating a rotatable disk or a flap valve shaft. The actuator includes a housing, a drive situated in the housing, and at least one position detector, in which a movably mounted piston rod in the housing is operatively connected to the drive for exerting a force effect, and in which the position detector includes at least one stationary Hall sensor and at least one magnet movable relative to the Hall sensor such that the magnet produces a magnetic field for generating a magnetic flux.
