Twin Tube Damper
Sachs N-Dampers operate on a twin-tube principle: When the axle encounters sudden loads, the piston rod moves in (compression). This pushes a quantity of oil corresponding to the volume of the piston rod through the damping base valve into the outer tube, while the annular volume of oil is pushed from the lower into the upper working chamber through the piston valve.
This pushes a quantity of oil corresponding to the volume of the piston rod through the damping base valve into the outer tube, while the annular volume of oil is pushed from the lower into the upper working chamber through the piston valve.
Function & Benefit
When the axle load is released, the piston rod retracts (rebound). The annular volume flows back through the piston valve and a quantity of oil corresponding to the volume of the piston rod is sucked in of the oil reservoir in the outer tube through the base valve.
- Long service life
- Greater ride comfort
- Low friction
- Multi-stage piston and base valves
- Ideal for modern air spring designs
- Even greater comfort with VARIO technology
