Frequency-Dependent Damping Valve Assembly And Vibration Damper

A frequency-dependent damping valve arrangement of a vibration damper for a motor vehicle, comprising:

• a cylinder that is at least partially filled with a damping fluid;
• a check valve;
• a carrier;
• a damping piston with the check valve, which damping piston is arranged inside of the cylinder and the damping piston is fastened to the carrier;
• a control arrangement arranged at the carrier coaxial to the damping piston that comprises:
• a control pot;
• and
• a control piston arranged in the control pot and slidingly axially displaceable at the carrier;
• a spring arrangement arranged to be slidingly axially displaceable between the damping piston and the control piston at the carrier and comprising:
• at least a substantially disk-shaped first spring element;
• a substantially disk-shaped second spring element;
• and
• at least one separating element arranged between the first spring element and the second spring element and which is slidingly axially displaceable at a carrier surface,
• wherein the first spring element and the second spring element axially contact the separating element by their respective radially central portion and axially contact the damping piston and/or the control piston at least indirectly by their radial edge portion.
