Abstract
A damping valve includes a damping valve body having at least one throughflow orifice which is at least partially covered by at least one valve disk by the action of a closing force. At least one spring body exerts an opening force on the valve disk that is less than the closing force. The at least one spring body is constructed as an elastomeric body separately from the control edge.
