FIELD: engines and pumps.
SUBSTANCE: proposed device incorporates silencer casing divided by partitions into two or more chambers, intake and discharge branch pipes and pipeline. The pipeline inlet end is located in the silencer last chamber, while its outlet end face is fitted coaxially in the discharge branch pipe. The pipeline length exceeds that of the discharge branch pipe. Pipeline area-to-discharge branch pipe circular area ratio makes 0.9 to 1.1. The pipeline can be arranged in silencer casing.
EFFECT: higher efficiency of silencing.
