Passive valve for attenuation of low frequency noise |
摘要 |
A passive valve assembly for an exhaust system is mounted within an exhaust tube. The exhaust tube has a bore that defines an exhaust flow path having a cross-sectional area. One end of the exhaust tube is to be connected to a first exhaust component and a second end of the exhaust tube is to be connected to a second exhaust component such that the exhaust tube forms a sole exhaust path between the first and the second exhaust components. The passive valve assembly includes a vane that is mounted within the bore, and which is moveable between an open position and a closed position. A resilient member biases the vane toward the closed position. When the vane is in the closed position, the vane covers 80% to 97% of the cross-sectional area.
