A turbocharger wastegate valve and method of operating a turbocharger wastegate

摘要

A turbocharger boost pressure control valve is provided. The turbocharger boost pressure control valve includes a cover plate which is actuatable in an open and a closed position, the open position allowing exhaust gas flow through a turbine bypass line and the closed position preventing exhaust gas flow through the turbine bypass line, and a vibration damping extension coupled to the cover plate and extends radially over a radial periphery of the cover plate. The exhaust gas flow acting on the extension consequently reduces the oscillation of the wastegate, thereby improving durability and reducing undesirable noise.
