Abstract

The invention relates to a damper having a damper cylinder, in which a piston plunger is guided via a piston rod. For the adjustment of characteristic damper values, the flow of a damper fluid can be controlled via control mechanism disposed inside the damper cylinder, which controls the flow of the damper fluid in a first flow direction using a first adjusting element and in a second flow direction using a second adjusting element. According to the invention, the first and second adjusting elements are provided with at least one spring element. The spring rate of at least one of the spring elements can be adjusted for defining a damping behavior using corresponding defining or predetermining elements.
