Abstract (en)

An expansion chamber (1) for an air filter assembly or an exhaust system of an internal combustion engine comprises an air inlet (7) to the chamber, and an air outlet (10) in one wall (2) of the chamber, the outlet (10) being positioned asymmetrically with respect to surrounding walls of the chamber and including a cow (9) defining an outlet orifice (10) which is inclined to the plane of the said one wall (2), thus reducing noise emitted by the chamber when used in combination with the engine.
