ABSTRACT:
A working cylinder for pneumatic or hydraulic pressure media for producing a rectilinear operating movement. The working cylinder has at least one operating chamber which receives the pressure medium and includes one stationary rigid housing part which preferably has the medium feed inlet thereon and a movable rigid piston part, both of which are interconnected pressure-tight by an elastically deformable envelope device and are guided together. The envelope device is constructed as a rolling-bellow diaphragm and is substantially closed all around and defines the operating chamber which receives the pressure medium.
