Abstract

The exhaust silencer for an ic-engine comprises a pipe (1) perforated between its inlet (2) and outlet (3) and containing intermediate walls (12,13,14), enclosed by a gastight housing (4,5,6) in which there are partitions (10,11), to form damping chambers (7,8,9) between housing and pipe. The gases flow to and fro between the pipe and the damping chambers. Each intermediate wall has apertures (15,16), so that some gas can flow in the axial direction of the pipe. The distance between the walls can be arranged to increase progressively in the axial flow direction.
