Abstract
1439524 IC engine exhaust gas silencers R A LISTER & CO Ltd 25 April 1974 [23 Aug 1973] 39900/73 Heading F1B An exhaust gas silencer comprises a casing 10 with inlet and outlet passages, baffles 11, 12, 13 being inter-connected so that their inner portions 11b, 12b, 13b form a central tube which defines a chamber 14 and outer portions 11a, 12a, 13a defining with the inner surfaces of the casing wall outer chambers 15, 16, 17, the chambers being serially connected to define a tortuous path between the central chamber 14, which forms one of the passages, and the most downstream outer chamber 17 to which the other passage (formed by openings 21) is connected, the line along which each outer portion 11a, 12a, 13a meets the casing wall being circumferentially spaced from a radius from the axis of the central chamber through a juncture of inner and outer portions. Gas entering central chamber 14 from the right in Fig. 1 passes through openings 18, 19 and 20 which are of progressively smaller area and leaves the silencer via openings 21. The left end of the chambers 14-17 are closed by an end-plate (not shown) as is the right end of chambers 15-17. In Fig.2 (not shown) a plug (22) defines the end of the inlet passage and openings (23) allow gases to pass from chamber 17 to leave the silencer by an opening in the left hand end-plate. The central chamber may be of circular or non-circular cross-section, Fig.3 (not shown). The baffle plates, which need not be three in number, are secured together as a sub-assembly with the outer portions of the baffle plates extending outwardly to an extent requiring their deformation to fit the sub-assembly into the casing to facilitate welding. The silencer may be directly attached to an exhaust manifold as in Fig.4 (not shown).
