Abstract

A pneumatic acturo cylinder has an integrl scanner for the end of the working stroke and the hollow piston rod contains rods, which are axially displaced by stops at one end of the two working strokes of the moving element. One end of the rods is connected to e.g. a slide of an information control, built into a cover of the pressure cylinder. The coupling system between the rods (13, c) is formed so that the adjustment of one element (24) relative to the other one, and a change in one end of the working stroke may be carried out from the outside of the housing (2). The end of the rods towards the control causes the axial displacement of the slide (24) in one direction, by the impact of a thickened part (18) at one end of the rods, on a threaded ring (23), screwed into the slide.
