Abstract

The device comprises a fluid dynamic cylinder (1) for driving the door opening and closing movement and means for damping said movement when the door nears its final open or closed position, and it is characterised in that said damping means comprise a telescopic body (2) and a moveable thrust washer (3) on the rod (4) of said fluid dynamic cylinder (1), said washer (3) being able to be fixed on said rod (4) in the desired position, so that when said washer (3) abuts with the telescopic body (2), it moves it and damps the door opening or closing movement.
It enables easily adjusting the damping means, as this can be done by simply moving the thrust washer along the cylinder rod.
