  • Sound attenuator of an exhaust-gas turbocharger
    Patent number: 9228549
    Abstract: A sound attenuator on the intake side of a compressor of an exhaust-gas turbocharger includes a tubular sound attenuator housing, which encases a flow duct between a face-side inlet opening and a rear-side outlet opening. A holding plate is provided in the sound attenuator housing in the flow direction and is perforated in the flow direction. For example, the holding plate can have a multiplicity of holes extending in the flow direction. The sound attenuator on the intake side of the compressor of an exhaust-gas turbocharger has a compact, lightweight and inexpensive structural form. The intake air is subjected to low resistance as it flows through the attenuation elements.
