Abstract

A positioning actuator operated by pressure means, in particular for a lifting, hauling or pushing device, is formed with at least one internal expansion body (7; 7.1; 7.2), which can be acted upon by a fluid with varying internal pressure, and at least one movable inner pressure body (6; 6.1) so that, with a change in volume of the expansion body (7; 7.1; 7.2), the pressure body (6; 6.1) experiences a change in position at least in certain areas, and at the same time the pressure body (6; 6.1) moved by the expansion body (7; 7.1; 7.2) is provided as the drive element of a transmission. <IMAGE>
