Abstract

1347787 Exhaust silencers TENNECO Inc 3 Aug 1971 [26 Aug 1970] 36446/71 Heading F1B In a silencer a plurality of sleeves 23, 25, 27, an inner tube 19 and a casing 3 define a zig zag flow path between a gas inlet 13 and an outlet 17. The tube 19 has main openings 49 at it's end remote from the inlet 13 for gas flow to the chamber 51 between the tube and the sleeve 23. The sleeves 23, 25, 27 have main openings 53, 57 and 61 respectively for gas flow to chambers 55, 59 and 63 and flow to the outlet 17 through the openings 65 and an outlet chamber 67. The tube 19 has louvre slots 81, 83 intermediate its ends opening to chambers 87 and 89 defined by a member 85 surrounding the tube. Louvre slots 91, 93, 95 are provided in the sleeves 23, 25, 27. The rings 29, 33, 37, 41, 43 and 47 locating the sleeves within the casing define chambers 69 and 75 with the casing ends 5 and 7. The chambers 69, 75 are open to the gas flow path defined by the sleeves through openings 71, 73, 77, in the rings 37, 41, 43 and to the outlet chamber 67 through openings 79 in the ring 47.
