Abstract

A pneumatic actuator consisting of an elongate, substantially cylindrical hollow body (1) impinged upon by a pressurized fluid. A pressure rod (2) which is resistant to bending and which can be stressed by axial forces is placed on the lower side thereof. The free end thereof is embodied as a node (3) to which two traction elements (4) are secured and the other end is embodied as a rotating joint (7) which rotationally connects the pressure rod (2) to a traction system (8). The axial ends of the hollow body (1) are respectively provided with a cap (5). The hollow body (1) is connected thereto along a casing line of the hollow body (1) in a non-positive fit. When the hollow body (1) is impinged upon by a pressurized fluid, the traction elements (4) are forced by the inflating hollow body (1) out of the straight connecting line between the fixing point (9) and the node (3) in the form of a screw and pull the node (3) into an activated position which is represented with dashed lines
