Adjustable damping mechanism for reducing oscillations within gaseous media

摘要

The oscillation damper (1) consists of a pressure tube in which a piston moves axially forcing the damping medium to pass in main and secondary streams through one of two identical butt mirrored spring valves (21a,21b) into controlling chambers (19) within the hollow piston rod (3). Each valve chamber is connected by a tube (19) to the space in the pressure tube on opposite sides of the piston. The valves allow the damping medium to flow into one controlling chamber, through a flow adjustable connecting tube (43) to the second chamber and exhaust it in the opposite direction through the connecting tube in the second chamber. The exhausting flow opposes the initial movement of the piston.
