Claims

[Scope of utility model registration request]

A plurality of cylinders made of walls filled with sound-absorbing material are installed concentrically inside the case, an expansion chamber is formed between each cylinder, the central cylinder is used as an exhaust inflow pipe, and the exhaust is connected to a part of the circumference of the case. An outflow port is provided, a heat insulating material is attached to the inner surface of the case located at the exit end of the exhaust inflow pipe, and the exit end is communicated with the adjacent expansion chamber outside through a transparent communication hole that does not pass through the sound absorbing material. A transparent communication hole leading to the adjacent expansion chamber is provided on the opposite side of the outlet □ end of the chamber, so that the exhaust is configured to meander sequentially through the plurality of annular expansion chambers, and small holes are provided in the sound-absorbing material-filled wall. A silencer equipped with a.
