Title: Valve which reacts as a function of pressure, especially for a vibration damper

Abstract: A pressure operated valve is provided including an adjusting device, a spring and a vent connection. The adjusting device is axially movably arranged in a pressure chamber defined in the valve and comprises a valve body and a pressure intensifier. A space between the valve body and valve face defines a valve passage cross section. The spring is operatively arranged for holding the pressure intensifier in a floating arrangement in the pressure chamber. The pressure intensifier has a first side exposed to a pressure in the pressure connection opening and a second side facing away from the pressure connection opening. The second side of the pressure intensifier and the adjusting device define a low pressure chamber within the pressure chamber. The vent connection is an inflow restrictor arranged between the lower pressure chamber and a space having a lower pressure than the low pressure chamber.
