Abstract (en)
[origin: EP2071269A2] The device has flexible boots (6a, 6b) integrated to a side of an end edge of an embrasure of a frame and to a side of a mobile unit i.e. arm tube, where the boots define an intermediate chamber (7) with a mobile wall (4) of the arm tube. The intermediate chamber is connected to an interior volume (10) of the frame, where the volume is pressurized by a pressurization unit (9) i.e. pump. Each boot includes a rod integrated to a lower web positioned near the mobile wall.
