  • the gas stream is imparted a substantially zig-zag pattern of movement, as indicated bythe flow arrows in the Figure.
  • the through-flow openings 10 and 11 of the baffles-8, 9 comprise a number of small holes disposed in tightly packed relationship so that the total area presented thereby provides a suitable throughflow' opening for the gas.
  • FIG. 2 illustrates an embodiment in which two intermediate partition walls 14 and 15 are attached in zigzag fashion to opposing portions or walls 12 and 13 of the casing 1, wherewith gas through-flow openings 16 and 17 are formed alternately between the walls 14,15 and opposing sides or portions 12 and 13 of the casing.
  • the openings 11 in the baffle 9 located behind the walls 14 and 15, as seen in the gas through-flow direction are located in the proximity of the casing portion l3,'a'nd that the gas outlet, comprising a connection means 2b, is located in the proximity of the opposite portion 12 of said casing so that the gas stream is guided in a zig-zag pattern as illustrated by the flow arrows.
  • Thewall 15 mounted downstream of the gas flow path through the silencer is arranged to capture the gas passing the wall 14, located upstream of said gas path, and to pass the gas generally rearwardly.
  • the casing can be provided with more than two intermediate walls.
  • the position and angle of inclination of the baffle wall 9 and also the position of the connecting means 2b in relation to the endwall of the casing depends on the number of intermediate walls arranged insaid casing. It is also possible to make the straight portions of the walls 14 and 15 in FIG. 2 substantially parallel to each other.
  • FIG. 3' illustrates one of several possible cross-sectional shapes of the casing 1, namely a rectangular cross-sectional shape.
  • the casing may also comprise two sides 18 and 19 of shorter length than sides 12 and 13 to form the illustrated rectangular cross-sectional shape.
  • the intermediate wall 14, similarly to the remaining intermediate walls, may suitably be sealingly connected to the three sides or walls l2, l8 and 19 of the casing while leaving the through-flow opening 16 between the intermediate wall and the wall 13 of said casing.
  • FIG. 3 Illustrates a casing of rectangular cross-section, it is obvious that other cross-sectional shapes are conceivable, such as for example a square cross-section, circular, oval or even polygonal crosssection. Irrespective of the cross-sectional shape of the casing, it is desirable that the sides of the intermediate walls arranged in the casing are firmly connected to or at least touch the inner surface of the casing, with the exception of .the side defining part of the through-flow opening.
  • the baffle means 37 is inverted with respect to the first baffle means 25 illustrated in FIG. 4, and with respect to the direction in which the point of the triangle extends relative to the adjacent intermediate wall.
  • the bafile means 38 is also inverted relative the baffle means 26 in FIG. 4, and an A generatris of the curved portion 7 of the intermedi- I ate wall 6 in FIG. 1 or the corresponding curved portions of the intermediate walls 14 and 15 of FIG. 2 is constantly parallel with itself and preferably also with one ortwo of the walls of the casing, in the illustrated cases the walls 12 and 13.
  • FIG. 4 illustrates an embodiment with which the silencer includes two baffle means and 26, each of which. includes at least two baffle walls 27 and 28 having through-flow openings disposed therein, said walls forming together with portions of the casing a container-like chamber 29 within the casing 1.
  • the chamber 29 may be of triangular configuration, or may be constructed to present some other configuration.
  • the walls 27 and 28 join at a common point, but can be separated from each other, although attached to the inner surface of the easmg.
  • the spaces formed between the baffle walls and portions of the casing can be either completely or partially filled with sound absorbing material such as mineral wool or steel wool.
  • an inlet opening 30 leading to a chamber 29 formed between the intermediate walls 27 and 28 and a casing portion25 is located close to or adjacent the portion 13 of the casing opposite the portion 12 adjacent'to which an outlet opening 31 of the chamber is located.
  • the outlet 31 is located opposite that portion of the casing adjacent to which a gas throughflow opening 32 is located between said casing and an intermediate wall 33.
  • the positioning of the upper baffle means 26 and its inlet and outlet openings depends on the number ofintermediate walls arranged in the casing. With the embodiment illustrated in FIG. 4, the intermediate wall 33 is curved along the whole of its length.
  • FIG. 5 illustrates an embodiment where the casing is provided with three intermediate walls 34, 35 and 36, each of which is curved along the whole of its length.
  • a baffle means 37 Arranged upstream of the intermediate walls is a baffle means 37, while a baffle means 38 is located downstream of said walls.
  • the bafile means 38 located downstream of the intermediodd number of intermediate walls is arranged in the embodiment of FIG. 6, as also in the embodiment of FIG. 4.
  • the inlet opening 39 of the baffle means 37 is located in the proximity of the narrowing portion of the space formed by said baffle means, while the outlet opening 40 of said baffle means is located on the opposite side of the arrangement and remote from the opening 39.
  • the casing, the intermediate walls and the baffle means may be made from heat resistant plastics material which may be reinforced to advantage with glass fibres or any other suitable reinforcing material.
  • heat resistant plastics material When such heat resistance plastics material is used, the intermediate walls and the baffle means, when embodied, should be fusion welded to the inner surface of the casing.
  • the intermediate walls and the baffle means When other material is used such as conventional sheet metals, for example, the intermediate walls and the baffle means may be secured by conventional welding techniques or by other appropriate methods.
  • the connecting means mounted on the casing 1 may comprise two or more concentrically arranged, although longitudinally displaced pipe portions of mutually different width or diameter.
  • An embodiment of such connecting means is illustrated in FIG. 1.
  • the connecting means 2a comprises a first pipe portion 41 located nearest the housing 1 and having the smallest width or diameter, a second pipe portion 42 of slightly larger diameter, and a third pipe portion 43 or larger diameter than the pipe portions 41 and 42, respectively.
  • the advantage of such a connecting means is that the silencer in question can be connected to exhaust pipes of different dimensions in a simple and convenient manner.
  • the exhaust pipe in question can be inserted in the outermost pipe portion 43 and, if too narrow to be sealingly accommodated by said pipe portion, can be moved through the connecting means until it is sealingly held by a pipe portion of the proper diameter or width.
  • the pipe portions located externally of the appropriate pipe portion can then be removed as by sawing and the pipe connected to the silencer.
