Abstract

The absorption silencer is for the engine of a cross-country vehicle in particular, having a perforated exhaust tube on which stuffing of heat-resistant and sound-insulating material such as mineral wool is wound. It comprises a casing in sections for assembly together, of heat-resistant material, threaded on and detachably fixed to the tube, with the stuffing in between. These are secured by front and rear annular joints, of heat-resistant and partly elastic material, and which seal the saing so that the exhaust gas cannot escape.
