Claims

[Scope of Claim for Utility Model Registration] In a silencer in which a porous inner cylinder is installed concentrically within an outer jacket cylinder to provide an annular sound-absorbing chamber, and the annular sound-absorbing chamber is filled with a sound-absorbing material, the porous inner cylinder 3 An abutting wall plate 11 having an expansion notch 10 on the periphery is installed inside one end, and the abutting wall plate 11 and the outer cover cylinder 1 are stretched.
A front diffusion chamber part 12 is formed between the end plate part 6' having the air inlet part 7, and a reflective wall board 13 is formed with a space between it and the abutting wall board 11. An end plate is stretched to form an intermediate diffusion chamber portion 14 between the reflective wall plate 13 and the abutting wall plate 11, and is provided with an outlet portion 9 of the reflective wall plate 13 and the outer cover cylinder 1. A rear diffusion chamber 15 is formed between the rear diffusion chamber 15 and the intermediate diffusion chamber 14, and a diffusion interference tube 17 having a plurality of aperture holes 16 on the circumferential surface is arranged, and the diffusion interference tube 17 is opened. other end 18
pass through the reflective wall plate 13 and face into the rear diffusion chamber 15, and inside the rear diffusion chamber 15, a sound absorbing material 5' is attached to the circumferential surface of the perforated cylinder 19, and a plurality of sound absorbing materials 5' are installed at one end of the perforated cylinder 19. The other end of the perforated tube 19 of the sound absorbing tube 20 is connected to the other end of the outer cylindrical body 1. A silencer communicated with the discharge port part -9 of the end plate part 8 at the end.
