1x Sachs Monotube Steering Damper for Mercedes Benz C-Class W201 W202 W124 Sedan

In gas-filled monotube dampers, the working cylinder is filled with oil and gas at a high pressure of around 25 to 30 bar. The floating separating piston provides absolutely leak-proof separation between the oil and the gas.

The SACHS monotube damper can be installed in any position. It operates at higher pressure than the twin-tube damper. The advantages of this are that it makes the lamellar valves in the piston highly responsive and also prevents foaming or bubble formation in the hydraulic oil.

Compression stage
Vehicle vibrations push the shock absorber together.
The piston valve provides resistance against the oil that flows up from the cavity below the piston. This slows down the downstroke.
The gas cushion compresses by the volume of the retracting piston rod.

Rebound stage
Vehicle vibrations pull the shock absorber apart.
The piston valve provides resistance against the oil that flows down from the cavity above the piston. This slows down the upstroke.
The gas cushion expands by the volume of the extending piston rod.
