Abstract

The exhaust silencer comprises an external casing (10) comprising a continuous wall (16,20,22,24) along which at least one cover piece (26A,26B,30,32,34) is added. Each cover piece extends only over a marked reduced region of the wall. The dimensions of the cover pieces and the connection between the cover piece and the continuous wall are such that they vibrate with a phase difference greater than 90o.
