ABSTRACT:
A muffler, especially for a portable internal combustion engine, particularly for driving a motor chain saw, which muffler comprises an exhaust gas receiving chamber which is defined by a chamber wall and by a pan-shaped housing wall including an inlet for the exhaust gases. Arranged on the inside surface of the chamber wall there is arranged an exhaust gas conveying passage communicating with the exhaust gas chamber and being adapted to deflect an exhaust gas current by preferably 90.degree.. This passage is adapted to convey the thus deflected exhaust gas current through an aperture in the chamber wall. Above this aperture on the outside of the chamber wall and projecting therefrom there is provided a bend from which the exhaust gas current through an outlet in the bend flows at least approximately parallel to a portion of the chamber wall. Furthermore, transverse to the out-flow direction of the exhaust current and spaced from the last mentioned outlet at least one turbulence creating member is provided for creating turbulence in the exhaust current having passed through the outlet.
