Hydraulic vibration absorbing system

The device has two or more parallel oscillation dampers with hydraulically connected working chambers. At least one hydraulic connection (1,2,3) has a valve unit (4), which closes the connection when there is a pressure drop in at least one of the oscillation dampers (5,6). Part of the hydraulic connection is a flexible conduit, the valve unit has 2/2 path valves, and has electrical or hydraulic control. At least one damper and/r the hydraulic connection has a pressure switch and/or pressure sensor.
