Abstract
Damper including a housing enclosing a working chamber and a compensating chamber, a damping fluid located at least partially in the working chamber, a guide and sealing unit, which terminates the housing at a first housing end, a piston rod sealed by the guide and sealing unit, and guided out of the housing, and a piston fastened to the piston rod and guided in the housing along the center longitudinal axis of the damper. The piston divides the working chamber into first and second part working chambers. Arranged at the end of the first and second working chambers, respectively, is a first and second closing element, with respective compensating channels, which form a through-flow connection between the respective working chamber and the compensating chamber. The piston device has at least one through-flow channel connecting the two part working chambers and having an adjustable effective flow cross-section.
