ABSTRACT:
The invention relates to a vibration damper consisting only of elastomeric parts of different hardnesses without any metal parts and comprising basically a layer of laterally spaced bodies (1) in the form of spheres, cubes, diamond studs, pyramids or the like distinct bodies, said layer of bodies (1) being sandwiched between two plate elements (2) of a harder elastomer than that of the said bodies (1), wherein the facing sides of the layer and the plate elements are geared to one another in such a way that the contact between them is limited to point-shaped or at the most line-shaped places of contact and for the rest the softer elastomeric bodies (1) are substantially freely deformable. In a preferred embodiment of the invention (FIGS. 6 and 8) the plate elements (2e) are provided on the sides facing away from the softer elastomeric bodies (1) with projections (9, 9a) which projections can deform and bend under vibratory loads and the pattern of projections (9, 9a) is such in relation to the position of the elastomeric bodies (1) that vibrations acting on the highest projections (9, 9a) are forced to travel along a curved path (19) through the said elastomeric bodies (1) and the energy thereof is absorbed in the damper.
