An exhaust silencer has supply and discharge pipelines, resonance chamber that has a body made of elastic material that forms resonance volume and restrictor of displacement of the body, and units for fixation to the pipeline. The resonance chamber is connected to the source of controlled pressure, and acoustic coupling to the pipeline is arranged by means of openings arranged in the pipeline within the cavity of the body and closed with dense acoustically transparent material. The openings act as a mouth of the resonance chamber. |
