Abstract

The present invention relates to a valve drive for actuating a valve, including a lifting element which shifts upon an actuation of the valve, and a displacement sensor by means of which the position of the lifting element can be detected, characterized in that the displacement sensor includes an elastically deformable dielectric film which is provided with at least two electrodes, the film being deformed by an adjustment of the lifting element.
