When the piston rod is moved, the damping medium of oil is pressed through the bores in the piston system. The damping force results from the resistance of the oil when flowing through the piston system. Due to the internal design of the piston system, the pull and push direction can be set independently of each other. The damping forces are dependent on the piston speed.

When the piston rod is moved, the damping medium of oil is pressed through the bores in the piston system. The damping forces are dependent on the piston speed.

Because the damping holes can be closed respectively to either side by way of valve washers, it is possible to regulate the damping forces in extension and compression directions largely independent of one another. The damping force upon compression determines the hardness of a shock absorber upon retraction. The damping force upon extension regulates the extension speed.
