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 is movable between a fully closed position where a maximum portion of the exhaust gas flow path is blocked by the vane and a fully open position where a minimum portion of the exhaust gas flow path is blocked by the vane. The closed position comprises a start position for the passive valve assembly when there is no exhaust gas flow. The vane is obliquely orientated to a plane that is perpendicular to a centerline of the exhaust component when the vane is in the start position.

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.

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 adaptive valve assembly includes a pipe defining a passageway for conducting engine exhaust gases, a pivot shaft supported by the pipe, and a valve body coupled to the pivot shaft. The valve body is moveable between an open position where exhaust gas flow through the passageway is increased and a closed position where exhaust gas flow through the passageway is reduced. A resilient member biases the valve body toward the closed position. A retainer assembly includes at least one damping feature that engages the resilient member to dampen vibrations.

摘要： A plastic muffler is configured to provide a controlled mode for releasing exhaust gas pressure during an over-pressurization event. The plastic muffler has a plastic casing that includes at least one pressure relief feature. The pressure relief feature allows exhaust gas to escape from the plastic casing when internal exhaust gas pressure exceeds a predetermined pressure level.
