Abstract
A controllable hydraulic vibration absorber is disclosed whose power cylinder and a tube defines a connecting duct which affords a balance of volume between both power chambers of the vibration absorber and a balancing chamber which is formed between the tube and an external tube disposed coaxially with it. The controllable vibration absorber valve affords variations of the vibration absorbing power and allows a flow through it in one direction only and is arranged between the connecting duct and the balancing chamber so as to be integrated as to its action in a valve assembly which is constituted by a non-return valve and by a switching valve. The switching valve is inserted between the second power chamber and the connecting duct.
