Abstract (en)
[origin: EP0826885A2] The pneumatic drive has a pneumatic duct (16) with a second valve system (25), with a second actuator unit (26) to switch it between open and closed positions. The unit is located in a second energy supply system (36) with operating switch (33), and a first controller switch (37) is located in series with the operating switch. The controller switch is mechanically connected to the drive output (8), so that in an intermediate position of that output, the switch is moved from a home into a switching position, and back into the home position after the output has passed through the intermediate position. Operating and controller switches are switched with the second valve actuator unit.
