    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.

    摘要： An exhaust component includes at least one muffler that has an inlet and an outlet. One pipe body is connected to each of the inlet and the outlet. The pipe bodies each have first and second ends that define a respective overall pipe length. Each pipe body defines a sole exhaust flow path between their first and second ends. A passive valve assembly is mounted outside of the muffler and within one of the pipe bodies. The passive valve assembly is positioned at a location within a first 25% of the overall pipe length of one of the pipe bodies relative to the inlet or outlet of the muffler.

    摘要： A control mechanism for a noise attenuation valve in a vehicle exhaust system is configured to significantly reduce operational noises. The noise attenuation valve includes a flapper valve (18) that is supported on a shaft (16) for rotation within an inlet tube (14). The shaft is coupled to an actuator (27) with a linkage assembly (30). The linkage assembly (30) includes a lever (42) that contacts noise attenuation pads (48) at maximum travel limits defined by a backing plate (46) to reduce operational noise. In one example configuration, the actuator provides a bottomless solenoid configuration and utilizes a pulse width modulation control module to further reduce operational noises.
