Beschreibung
Zusammenfassung:	An engine turbocharger includes a turbine housing having wastegate passages integral therewith and a cartridge wastegate valve including a ported stationary bushing and a ported tubular valve member rotatable in the bushing to close or open wastegate flow. The arrangement provides simplicity of manufacture and installation as well as a self-cleaning valve design that is unbiased by exhaust gas pressures and thus requires a minimum of operating force.
