Abstract
A damping valve arrangement () for a vibration damper includes a damping piston () with a check valve, which damping piston () divides a cylinder () of the vibration damper into a first working chamber () and a second working chamber (), and a control arrangement () with a control pot () and a control piston () which is axially movable therein. A connection channel () connects the first working chamber () to the second working chamber (). The connection channel () is arranged such that it is at least partially closed by the control piston () during an axial displacement of the control piston () in direction of the damping piston () and opened again during an axial displacement of the control piston () in direction of the pot base ().
