  • Publication number: 20070080314
    Abstract: A bushing assembly for an exhaust valve includes a first bushing component formed from a first material that provides a low friction surface and a second bushing component formed from a second material that provides noise damping. The first and second bushing components are supported by a shaft that rotates an exhaust valve positioned within an exhaust component. An actuator is coupled to the shaft to pivot the exhaust valve within an exhaust component to vary exhaust flow. As the shaft rotates, the first and second bushing components cooperate to provide a good bearing surface in combination with noise dampening during valve actuation.
