A b s t r a c t Main Figure: Fig. 3a A damping element (10) comprises disintegrated closed-cell foamed material such as loose shreds or incoherent granules (14) of polyurethane foam under predetermined stress within an envelope (12) of an elastically yielding material of given fluid permeability and made from a format (16) of fiber mate- rial such as jute, fleece or elastic fabrics of given densi- tyl perforated plastics foil, etc. When compression-filled with the granulated material (14), it is permanently closed by sewing up, sealing or conglutinating adjacent edges or seams (18) to form e.g. a cylindrical or bale-type body or a tubular body with a through-hole (20). The envelope (12) may be encircled by a force-receiving container having a shell (26) mounted to rims (25) of a cover (22) and a bottom (24). Preferred use is in supporting structures such as machine beds, engine bearers, three-dimensional bearings, shock ab- sorbers, telescopic cylinders, air cushions, etc. with or without oil impregnation. It is also suitable for emergency supports or makeshift bearings.
