Vibration damper with variable damping force has variable damping effect damping valve and including non-return valves and damping valve connected in series for each pressure direction

摘要

The vibration damper has a cylinder filled with a damping medium with an axially movable piston (4) with a piston rod that divides the cylinder into two working chambers (7,8). The damping force in the push and pull directions is influenced by non-return valves working in each direction. There is a variable damping effect damping valve (3) controlled by an electromagnet. The non-return valves and the damping valve are connected in series for each pressure direction.
