Abstract (en)
[origin: EP1577514A2] The silencer (10), especially for exhaust gases of an internal combustion engine, has at least one hollow chamber structure (20) installed inside the silencer casing (14). The casing has at least one inwards projecting protrusion (24) by which the hollow chamber structure is fixed inside the casing. The protrusion is formed by a plastically deformed section of the casing and is in the form of a crease. The silencer may have several protrusions which are spaced apart in the circumferential direction and/or axially.
