Abstract
A muffler for combustion engines in which a housing is subdivided by means of bottoms into at least two successively arranged reflection chambers. Into the first inlet-side reflection chamber an exhaust entry pipe extends. An intermediate channel extends through at least one of inner bottoms from the first into at least one reflection chamber. An exhaust outlet pipe extends from the last reflection chamber out of the muffler, and has at least, in the region of the last reflection chamber, at least one inlet opening. The intermediate channel is arranged in the form of a plurality of intermediate channels which are flowed-through in one and the same direction, and each channel has a small cross-sectional area in relation to the cross-section of the exhaust inlet pipe.
