摘要： There is disclosed a silencer for attenuating sound waves produced in a fluid that circulates through a fluid conveyer. The silencer comprises an expansion chamber that is in fluid communication with the fluid conveyer, and which carries sound waves there through; a sound wave dissipater provided with the expansion chamber and arranged to absorb sound waves traveling there through; a resonator operatively associated with the sound wave dissipater and constructed and arranged to cause attenuation and reflection of the sound waves back and forth towards the sound wave dissipater; the expansion chamber having a chamber: conveyer cross-sectional area ratio and chamber length characteristics allowing maximum transmission loss for a given frequency. The expansion chamber has an exit to allow fluid containing attenuated sound waves to escape therefrom.

摘要： In the silencer of the present invention, a cylindrical porous plate is provided on the outer circumferential side of a path forming component that forms a sound absorption path. The porous plate has a plurality of micro holes penetrating it in the thickness direction. By forming the plurality of micro holes on the outer circumferential side of the porous plate, sound generated by the air flowing along the sound absorption path is attenuated without any sound absorption material being used. The porous plate is formed from metal. As a result, there is no source for generating for dust and dirt such as sound absorption materials formed, for example, from connected foam resin and fiber. Accordingly, it is possible to reduce sound that is generated by the flow of air while also reducing the creation of dust and dirt.

摘要： A muffler includes three or more concentric pipes which convey exhaust gases from an input end of the muffler to an output end of the muffler. The exhaust gases reverse direction as they pass from a first pipe into a second pipe, and again as they pass from the second pipe into the third pipe. After the exhaust gases have reversed direction twice, they exit the muffler. Perforated portions of the three concentric pipes can be used to allow exhaust gases to pass from one pipe into another.
