  • Hybrid valve for attenuation of low frequency noise
    Patent number: 9376947
    Abstract: A hybrid valve assembly for an exhaust system includes an exhaust tube having a bore defining an exhaust flow path. A vane is mounted within the bore and is moveable between an open position and a closed position. A resilient member biases the vane toward the closed position. A valve actuator has an ON position where movement of the vane is actively controlled by the valve actuator and an OFF position where movement of the vane is passively controlled by exhaust gas flow.
