A silencer is provided for reducing noise from exhaust gases from an internal combustion engine. The silencer is of the type having an outer cylindrical cover and a coaxial inner cylindrical tube which define between them an annular cylindrical chamber into which the exhaust gases which enter the silencer are admitted. The inner tube is a perforated tube, a first open end of which forms the sole admission orifice for the gases into the silencer and the other opposite end of which is closed. The inside wall of the outer cover is lined with a layer of absorbent material mounted about the inner tube along substantially the entire perforated length of the inner tube.

A silencer for exhaust gases from an internal combustion engine, comprising: an outer cylinder cover; a single inner cylinder tube mounted coaxially within said outer cylinder cover to form an annular chamber between said inner cylinder tube and said outer cylindrical cover, said inner cylindrical tube being formed with a plurality of perforations therein and having a first open end for admission of the exhaust gases therethrough and a second closed end opposite said first open end, said second closed end comprising means for reflecting the exhaust gases as the exhaust gases impinge thereagainst; a layer of absorbent material mounted about said inner cylindrical tube longitudinally along a substantial portion thereof; wherein said annular chamber defines a means to allow the exhaust gases to flow substantially unhindered from said perforations formed in said inner tube to said layer of absorbent material; and wherein said layer of absorbent material defines a means for absorbing noise from the exhaust gases as the exhaust gases pass therethrough.
