<p>A muffler for small internal combustion engines, such as for a chain saw, is disclosed. The muffler has a chamber enclosed by a chamber wall and a dished housing wall. The housing wall contains an inlet for the exhaust gases. A gas duct is arranged on the inside of the chamber wall and deflects the gases through at least 90.degree. before exhausting them through an opening in the chamber wall. The gases then pass through an elbow that deflects them further and along the surface of the chamber wall to an element perpendicular to their paths, to impact turbulence.</p> |
