Abstract
An adjustable damping valve device has a first adjustable damping valve assembly for a first flow direction and a second adjustable damping valve assembly for a second flow direction. The two damping valve assemblies are adjustable independently from one another, and the first damping valve assembly generates a damping force for only one flow direction and the second damping valve assembly has a minimum cross section through which damping medium can flow in the setting for maximum damping force so that the second damping valve device generates a damping force in both flow directions.
