Special means providing automatic damping adjustment,; i.e. self-adjustment of damping by particular sliding movements of a valve element, other than flexions or displacement of valve discs; ;; Special means providing self-adjustment of spring characteristics
resulting in the damping effects during contraction being different from the damping effects during extension; , i.e. responsive to the direction of movement
