<p>A vibration damper for a chimney comprising a partly liquid-filled container which is positioned at the top of the chimney and in which a plurality of perforated plate members are secured, said plate members extending from the bottom of the container and upwardly in a manner such that the plate members divide the container into separate spaces which are in mutual flow communication via the perforations of the plate members, and which additionally comprises at least one substantially horizontal perforated plate member at the surface of the liquid. The resulting vibration damper, which has an inexpensive, relatively maintenance-free structure, has improved damping properties over the prior art.</p> |
