Abstract
The invention relates to a damper having a damper cylinder, in which a piston ram is guided via a piston rod, and for adjusting characteristic damper values, the flow of a damper fluid can be controlled. A piezoelectric valve is disposed inside the damper cylinder, and includes a piezoelectric element and an actuator, and an evaluation and control circuit for adjusting the flow of the damper fluid triggers the actuator via the piezoelectric element.
