DAMPER FOR DAMPING VIBRATIONS WITH A DAMPING BODY PROMOTING FORMATION OF FOAM

摘要

The present invention concerns a damper for damping vibrations. The damper includes at least one substantially longitudinal damping body (1) with two end surfaces (21, 22) and one substantially longitudinal surface (20) between these. The damping body (1) includes a longitudinal direction (a) and a transversal direction (t) and is places in a substantially longitudinal cavity (15) with a damping fluid, wherein the cavity (15) defines at least one cavity surface (14) and the damping body (1) defines at least one damping surface. The damping fluid includes a proportion of liquid and a proportion of gas and either the cavity surface (14) or the damping body surface or both are broken to promote formation of foam in the damping fluid in operation.
