Abstract (en)
[origin: EP1980756A2] The fluid-operated rotary drive (1) has a rack chamber (28) carrying a rack (16) and extending from a drive piston (25) as far as a rear wall and continuously connected to atmosphere. A drive part in the rack chamber carries a fluidic shock damper (38) separated in sealed manner from the actuating chamber by the drive piston and that cooperates with a stop surface on the rear wall to brake the working movement.
