To provide a muffler that does not affect a muffling effect due to a state of adhesion with a main pipe, deformation or bending of the main pipe, and is easy to adjust according to frequencies, and has a wide range of frequencies having the muffling effect.SOLUTION: There is provided a muffler 1 inserted into a main pipe 2 through which fluid flows, which comprises an inner tube 3 located inside the main pipe 2 and a plurality of ribs 5 supporting the inner tube 3 on the inner surface of the main pipe 2. A fluid flow path 6 is provided on the outside of the inner tube 3, and a muffling space is provided on the inside of the inner tube 3. A plurality of muffling spaces divided by one or more partitions 4 are provided on the inner side of the inner tube. The muffling spaces may be side branch chambers 7a, 7b, resonance chambers or a combination of these.SELECTED DRAWING: Figure 2
【課題】主管との密着状態、主管の変形や曲がりによって消音効果に影響を与えない、また、周波数に応じた調整が容易で、消音効果を生じる周波数の範囲が広い消音装置を提供する。【解決手段】流体が流れる主管2に挿入される消音装置1であって、主管2の内側に位置する内管3と、内管3を主管2の内面に支持する複数のリブ5とを有する。内管3の外側に流体の流路6が設けられ、内管3の内側に消音空間が設けられている。内管の内側に1又は複数の仕切部4により区画された複数の消音空間が設けられている。消音空間は、サイドブランチチャンバ7a、7b、共鳴チャンバ又はこれらを組み合わせてもよい。【選択図】図2
