Abstract
A muffler for combustion engine in which a housing is subdivided into at least two successive reflection chambers. An exhaust gas inlet pipe enters the first input reflection chamber, and intermediate channels are provided for communicating between the reflection chambers. An exhaust gas outlet pipe terminates in the last reflection chamber. A corrugated metal sheet is provided on the inner side of the housing, and cooperates with that inner side so that each corrugation of the metal sheet forms an intermediate channel with the inner side of the housing. The region of the opening of the exhaust gas inlet and outlet pipes is surrounded by a respective chamber housing. Each chamber housing forms a closed reflection chamber and abuts the inner side of the corrugated metal sheet to form a plurality of mutually separated guide channels.
