Abstract
An actuator includes a housing, an extension arm, and a threaded spindle. The threaded spindle is mounted on the housing in such a way as to be rotatable with respect to an axis of rotation by a first rotary bearing. The extension arm projects out of the housing in such a way that it can be moved in a direction of the axis of rotation. The housing and the extension arm together delimit an internal space, the volume of which changes when the extension arm moves. A first end of the threaded spindle that is remote from the first rotary bearing, projects into a tubular section of the extension arm, irrespective of a position in which the extension arm is situated. The tubular section extends with a constant internal cross-sectional shape along the axis of rotation.
