Abstract

The hydraulic damper has a second by-pass valve (Z) which is arranged between a control connection (3) of the valve unit (V) and an outlet pipe (9'). The by-pass valve can be switched to a through flow position in the pressure transmitting direction. A transmission piston (K) subject to the control pressure pipe (1) is provided in the by-pass valve. The piston acts on the by-pass valve in accordance with the pressure difference between the control pressure pipe and the outlet pipe in the closing direction.
