For transmission of an axial movement of an activation piston (10), as a rotary movement of an output shaft (22) is used an intermediate tube sleeve (16) which is picked up non-turnably, yet displaceably, inside a fixed tube section (4) of an actuator housing (2,6). The tube sleeve (16) has opposed axial tracks (20) to catch a cross-pin (18) on the fixed tube section and also a helical track (26) to catch a projecting tap (24) on the output shaft (22). All pertinent wear and tear will appear on the tube sleeve and the applied taps, and these parts will be easy to replace in addition to which they may be produced in a wearresistant embodiment. |
