A muffler, especially for an internal combustion engine of a chain saw, comprises a primary and a secondary chamber through which exhaust gases from the engine in turn flow. The primary chamber (10) is formed by an inner, generally spherical receptacle (11) which is surrounded by an outer receptacle (12), and the secondary chamber (13) is formed by the space between the receptacles. The dimensions of the receptacles are such that the volumes of the chambers are generally equal. |
