ABGAS-SCHALLDAEMPFER

A completely open gas silencer is disclosed, which comprises an elongated hollow baffle casing having an open end and a closed end. An inlet conduit is attached to the closed end of the baffle casing. An end portion of the inlet conduit extends into the baffle casing. This end portion is coaxially encircled by a hollow cylinder having a plurality of perforations formed on its cylindrical wall. A filter cap is removably mounted on the hollow cylinder and located transversely and directly opposite to the end opening of the inlet conduit. A porous member is mounted in the filter cap to break up the exhausted noisy gas into a number of random gas streams in order to reduce the gas velocity. A lining of sound absorbing material is disposed on all inside walls of the baffle casing to absorb the noise in the random gas streams.
