ABSTRACT:
The invention relates to a device for opening of doors. Electromechanical systems contain many expensive components and are thereby expensive to manufacture. Installed electromechanical systems are expensive in operation by virtue of the high and energy-demanding friction which always are present in mechanical constructions. The present operating device is less energy-demanding by the formed transmission of power via two piston-like parts (5and6). A driving device (2) is arranged to drive the piston-like part (5) and the second piston-like part (6) is connected to an operable element.
