Abstract

1471417 Exhaust silencers THIELMANN AG Gebr 4 April 1974 [ 10 May 1973] 14902/74 Heading F1B A silencer for the exhaust gas of I.C. engines comprises an inlet conduit 2 and an outlet conduit 4 connected by an inside tube 3 surrounded by an outer casing 5 to form a flow channel 6 in parallel with the flow-path through the inside tube 3, which has openings 8, 10 through which exhaust gases can flow. In the flow channel 6 are directing plates 24 having rings of openings 26, 25, 27, the last two mentioned rings causing rotation of the gas flow clockwise and counter-clockwise respectively. Within the inside tube 3 there may be a directing element 18, containing sound absorbent material and having inlet openings 22 and outlet openings 23 with flow channels 21 provided between the directing element and the inside tube.
