Abstract

1. Reflex exhaust gas silencer, especially for internal combustion engines in motor vehicles, with exhaust gas pipes passing through the silencer chambers, tuned resonators being coordinated with the exhaust pipes at the inlet side of the exhaust gas silencer chamber, characterized in that the inlet exhaust pipe (6) comprises a radial opening (9) spaced from and upstream of the gas exhaust opening (16) to the silencer chamber (I), which opening is covered by an arched metal sheet (10) in such a manner that there are formed two axial, sickle-shaped coupling openings (12) which lead into the silencer chamber.
