Damper
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.
