Abstract
A damping valve arrangement for a vibration damper is disclosed. This damping valve arrangement includes a damping piston with a check valve and a control arrangement with a control pot and a control piston that is axially movable therein. The control pot is shaped from a sheet metal has at least one stop that projects into the control space, axially supports the control piston at least indirectly, and defines a soft damping force characteristic. The stop is produced by a plastic deformation of the control pot.
