Abstract
A pressure-dependent valve, for use with an adjustable vibration damper comprising a piston rod arranged in an axially movable fashion in a cylindrical tube filled with damping fluid, is controlled by a pressure transducer pressurized via a pressure connection opening. The pressure-dependent valve includes a valve body axially movable relative to a valve surface. The valve body and valve surface together determine a valve passage cross-section. The pressure transducer is float-mounted in a pressure space and supported by at least one spring. One of the valve parts determining the valve passage cross-section is movable relative to the current position of the pressure transducer by an adjustment device.
