Abstract
The pressurised compartment (20) is defined by the damping valve disc (9, 10), an elastic element (11, 12), and by the wall-parts of the piston (1) and or of the piston insertion rings containing the orifices in the bypass-duct system. The elastic element of the pressurised compartment belonging to the opposite-facing operating compartment seals the pressure chamber from the appropriate operating chamber, when the pressure in the pressure chamber is higher than the operating compartment. The elastic element is opened by the pressure of the medium occurring in the opposite facing operating compartment, when the pressure of the medium exceeds the pressure in the pressure chamber.
