Abstract (en)

The insert (1) has a jacket (4) filled with damper material. The jacket is pref. mainly tubular and is without seams in longitudinal direction (5) and/or is elastically flexible. This allows the insert to be fitted into resp. adapted to a retainer chamber (6) of the silencer (2). The jacket is formed from one or two parts of an esp. continuous hose. One jacket end is pref. folded outwards to form a ring chamber for the damper material (3). The jacket is of wide-meshed and/or knitted material, non-woven material and/or braiding, mineral and/or organic material. The damper material is fiber-like and/or elastically compressable, is esp. heat resistant, and is esp. glass, silicate, silicate/calcium, and/or organic fibers.
