摘要： An exhaust valve assembly includes a flapper valve fixed to a valve shaft where the flapper valve is movable between a closed position, an intermediate position, and an open position. A resilient member biases the flapper valve toward the closed position. An electric actuator actively moves the flapper valve at least from the closed position to the intermediate position. A coupling mechanism couples the valve shaft to an electric actuator shaft and allows the flapper valve to move to the open position in response to exhaust flow sufficient to overcome a biasing force of the resilient member without requiring input from the electric actuator.

摘要： A passive valve assembly for an exhaust component includes a vane that is positioned within an exhaust gas flow path. The vane is pivoted from a closed position to an open position in response to exhaust gas flow overcoming a biasing force. A stop is positioned within the exhaust component and cooperates with the vane to define a closed position for the vane.

摘要： A passive valve assembly for a vehicle exhaust system includes an exhaust component that defines an exhaust gas flow path and a vane that is positioned within the exhaust gas flow path. The vane has an elongated body structure that has a greater height than width. The vane is positioned to provide a high percentage of coverage when closed but is able to pivot to a fully horizontal position when open to allow maximum flow.

摘要： An exhaust valve includes a valve body that is fixed for rotation with a shaft supported by at least one bushing. A single spring is used to bias the shaft to hold the valve body in a valve closed position, and to exert an axial load on the shaft to seal the shaft against the bushing to prevent exhaust gas leakage.

摘要： An exhaust component includes a wall with an inner surface defining an exhaust gas flow path. A passive valve assembly includes a vane that is positioned within the exhaust gas flow path to be pivotable between open and closed positions. The vane is defined by a plane that extends across a width of the vane. The vane is supported by a shaft that defines an axis of rotation. The axis of rotation is offset from the plane of the vane such that the vane can be pivoted to a fully open position without interfering with the inner surface of the wall.
