Abstract (en)
In an engine exhaust silencer the gases are first led along an elongate annular passage, defined between two chambers mounted one within another, and are then funnelled into and along an elongate exhaust tube whose longitudinal wall is perforated and is surrounded by one or more noise attenuating chambers. The outer wall of the annular passage converges towards, but ends just short of, the elongate exhaust tube, and the gap between the two is surrounded by and opens into an expansion chamber which joins and seals the annular passage exit to the exhaust tube inlet.
