Patent abstract
A sound damping device (4) for a tubular duct (2), particularly a gas transporting tract of an internal combustion engine (1) having a least one bypass channel (5) running parallel to a main duct (6) in a section of the duct (2). The bypass channel (5) is longer than the main duct (6) between a branching off point (7) and a re-entry inlet (8). The bypass duct according to the invention is configured as a spiral duct (5) which winds around the centrally disposed main duct (6) in order to decrease the installation space requirements for the noise suppressor (4).
