Abstract:
The present disclosure relates to a valve arrangement for a shock absorber. The valve arrangement comprises a valve member axially moveable relative a housing, and a triple spring arrangement including a first spring, a second spring and a coil spring arranged between the valve member and a coupling member coupled to the first spring and the second spring. The valve arrangement is adapted so that when the valve member moves no more than a first stroke length relative a predetermined reference position the first spring deflects to adjust a force equilibrium of the valve member, when the valve member moves more than the first stroke length the second spring deflects to adjust said force equilibrium, and when the valve member moves beyond a second stroke length greater than the first stroke length, the coil spring compresses to adjust said force equilibrium. A shock absorber comprising such a valve arrangement and a method for controlling a damping medium flow in a shock absorber is disclosed as well.
