Abstract (en)
[origin: WO2006074915A1] The invention relates to an axially driven piston-cylinder unit comprising a cylinder (2), a piston (3) that can be moved back and forth in the axial direction of the cylinder (2), between a first piston position wherein the cylinder volume (18) defined by the piston (3) and the cylinder (2) is maximal, and a second piston position wherein the cylinder volume is minimal, and a drive element (50) that can be moved back and forth in the axial direction of the cylinder and is mechanically connected to the piston (3) by means of a piston rod (4). The invention is characterised in that the piston rod (4) is connected, on the first end (4') thereof and/or on the second end (4") thereof, to the piston (3) or to the drive element (50), by means of an elastic device (6), against the pretension of the elastic device, in such a way that it can be moved axially in relation to the piston (3) or the drive element (50), such that when the piston head (16) comes into contact with the front wall (12) of the cylinder borehole (10), on the side of the cylinder head, the other movement of the drive element (50) is performed against the force of the elastic device (6), thus braking the drive element (50).
