Vibration damper has damping valve unit that is arranged on piston, where connection in piston, between piston-rod side working chamber and piston-rod side remote working chamber, is openable via damping valve unit

摘要

The vibration damper has a cylinder (1), which is filled with a damping medium, where a piston rod (2) is axially movably guided in the cylinder by a piston rod guide (3). A piston (4) divides the cylinder in a piston-rod side working chamber (5) and a piston-rod side distant working chamber (6). A damping device (12) is arranged on piston for producing amplitude-selective damping force. A damping valve unit (14) is arranged on piston, and a connection in the piston, between the piston-rod side working chamber and piston-rod side remote working chamber, is openable via the damping valve unit.
