| 摘要 |
The invention relates to a silencer for the exhaust gas or suction air of a combustion engine or for some other pulsative gas flow, whereby the silencer can be connected between an inlet flow duct (1) having a first cross-sectional flow area (A1) and an outlet flow duct (2), and whereby the silencer comprises a plurality of individual silencer channels (3) having different lengths and being arranged in parallel regarding the flow (F3), whereby the gases (10) pass through the silencer channels from the inlet flow duct to the outlet flow duct. The total combined cross-sectional flow area (A3) of all silencer channels is not substantially smaller than said first cross-sectional flow area (A1). The silencer further comprises a mixing chamber (4) which is located between the outlet openings (5) of the silencer channels (3) and the outlet flow duct (2). The silencer channels discharge into the mixing chamber common to all silencer channels, whereby the cross-sectional flow area (A4) of this mixing chamber is substantially larger than the total combined cross-sectional flow area (A3) of the silencer channels. |
