The pipe 206 is provided in the illustrated embodiment. The suction tube 202 made of a porous tubular having a plurality of holes 202a is positioned so that its front end is located at the front end surface of the body 201, and the rear end thereof is divided into partitions 204 and 205. A porous tub that is disposed on one side of the body 201 so that it is located in place in the rearmost space 209 of the interior spaces 207, 208, and 209, and the plurality of holes 203a are drilled. The broiled discharge pipe 203 is located in place in the frontmost space 207 of the spaces 207, 208, 209 inside the body 201 with its tip divided into partitions 204, 205. The rear end is located at the rear end of the body 201 and is disposed on the other side of the body 201. In another location within the body 201 is a connecting tube 206 with holes 206a communicating with the spaces 207, 208, 209 inside the body 201. Among the partition walls 204 and 205 of the rear muffler 200, the partition wall 205 is formed with holes 205a as shown in FIG. 6, and the partition wall 204 has the suction pipe 202 and the discharge pipe ( 203, through holes for the connection pipe 206, etc., are free from other holes. The rear muffler 200 is entirely connected to the rear end of the discharge pipe 103 of the muffler 100 through the front end portion of the suction pipe 202 through a conventional connecting pipe means.

작용에 있어서, 전부 머플러(100)의 흡입관(102)을 통과한 엔진 배기기스는 먼저 격벽(104)과 격벽(105)사이의 공간(109)으로 배출 팽창됨으로써 음의 감쇄가 이루어지는 동시에 상기 흡음관(102)둘레에 배치된 흡음재(106)에 의해 소음효과가 배가되어진다. 이와 같이 흡입관(102)을 통해 나온 배기가스는 다시 나팔형상의 확대된 직경의 선단부를 가진 배출관(103)으로 인입 통과하면서 수축, 팽창되어 음의 감쇄가 이루어지고, 이때에도 상기 배출관(103) 둘레에 배치된 흡음재(107)에 의하여 소음효과가 배가된다. 또한, 상기 전부 머플러(100)의 배출관(103)을 통해 나온 배기가스는 도시되지 않은 연결관체를 통해 후부 머플러(200)의 흡입관(202)으로 인입통과된 후 그 일부는 상기 흡입관(202)의 구멍(202a)들을 통해 공간(208)으로 배출되고 이 가스는 연결관(206)의 구멍(206a)들을 통해 공간(207)으로 빠져 나간다. 한편, 상기 흡입관(202)의 후단부로부터 배출되는 가스는 공간(209)내에서 팽창되면서 음의 감쇄를 이룬 후 연결관(206)을 통해 다시 수축진행되어 공간(207)내로 배출 팽창되고, 공간(207)내의 가스는 배출관(203)으로 인입 배출된다.In operation, the engine exhaust gas, which has passed through the suction pipe 102 of the muffler 100, is first discharged and expanded into the space 109 between the partition 104 and the partition 105, so that a negative attenuation occurs at the same time. The noise effect is doubled by the sound absorbing material 106 disposed around the periphery. As described above, the exhaust gas emitted through the suction pipe 102 is retracted and expanded as it passes through the discharge pipe 103 having the tip portion having an enlarged diameter of a trumpet shape, and thus attenuates negatively. The sound effect is doubled by the sound absorbing material 107 disposed in the. In addition, the exhaust gas from the exhaust pipe 103 of all the muffler 100 is passed through the inlet pipe (202) of the rear muffler 200 through a connecting pipe not shown, a part of the suction pipe 202 It is discharged into the space 208 through the holes 202a and the gas exits into the space 207 through the holes 206a of the connecting pipe 206. On the other hand, the gas discharged from the rear end of the suction pipe 202 is expanded in the space 209 to form a negative attenuation and then contracted again through the connecting pipe 206 is discharged and expanded into the space 207, the space The gas in 207 is drawn in and discharged to the discharge pipe 203.

따라서, 본 고안은 상기와 같은 다단계의 팽창, 수축 및 흡음작용의 반복으로 매우 효과적인 소음작용을 제공하는 전부 머플러(100) 및 후부 머플러(200)의 조합구성에 의해 이상적인 소음작용을 제공하면서 가급적 간소한 구성으로 제작이 용이하고 오랜 수명을 유지하는 뛰어난 효과를 제공하는 것이다.Therefore, the present invention provides an ideal noise action by providing a combination of the whole muffler 100 and the rear muffler 200 as simple as possible while providing a very effective noise action by repeating the multi-step expansion, contraction and sound absorption as described above. It is easy to manufacture in one configuration and provides an excellent effect for long life.
