  • Vibration damper with adjustable damping force
    Publication number: 20080116024
    Abstract: A vibration damper with adjustable damping force, including a valve body and an actuator. The actuator causes the valve body to move toward a valve seating surface against a nonlinear elastic force, thereby creating a characteristic curve, which describes the function “open valve cross section-versus-energy input to the actuator” and which has at least two ranges with different slopes.
