Monotube damper

Function

• Oil and gas are strictly separated from each other by the movable separating piston. The damping valves for rebound and compression are located on the piston.
• The piston rod and seal are especially important components, because the pressurized system must remain perfectly sealed under dynamic loads. The Viton seal is applied to the piston rod by means of mechanical pre-loading and high internal pressure.
• Compression: When the piston rod moves in, a quantity of oil equal to the volume of the piston rod compresses the gas chamber by means of the movable separating piston.
• Rebound: When the piston rod retracts, the gas chamber expands and pushes back the separating piston.

Vibrational damping in both directions takes place via the multi-stage piston valve.

 

Design

1. Piston rod
2. Sealing system in the piston rod
3. Coated guide bushing
4. Working piston and piston valve
5. Operating cylinder with oil reservoir
6. Floating separating piston
7. Gas pressure to support compression damping forces

Benefit

• Lower noise levels
• Precise damping even for smallest, high-frequency axle movements
• Any installation position thanks to seperation of oil and gas
• No oil foaming
• Low weight

Used in all vehicles classes, sports cars, SUV's and pick-up trucks.
