Twin Tube Damper

Twin-tube dampers require lower gas pressure levels as monotube-dampaers; 6-8 bar are enough to ensure precision damping as well as low noise levels even at high compressione speeds.

Function & Benefit

When the piston rod moves in (compression), part of the oil flows from the lower working chamber through the piston valve into the upper working chamber. A quantity of oil corresponding to the volume of the piston rod is pushed through the base valve into the equalization chamber. When the piston rod retracts (rebound), the piston valve takes over the damping function, while a quantity of oil equal to the volume of the retracting piston rod flows back through the base valve.

Function

  1. Piston rod
  2. Seal and guide unit
  3. Working piston
  4. Oil compensation chamber
  5. Working piston and piston valve
  6. Base valve

Benefits

  • Low friction
  • Greater ride comfort
  • Variable curve configuration thanks to multi-stage piston and base valves
  • Short installation lengths
