Abstract (en)

[origin: WO02092985A1] The invention relates to the return stroke between an actuator and an element. In order to displace the element the actuator (A) is impinged upon by a control voltage (ANS). The control voltage (ANS) is selected in such a manner that it is dependent on the size of return stroke in order to compensate the alteration in the return stroke.
