More Information
Summary:A turbocharger includes a turbine housing and a wastegate valve. The turbine housing defines a bypass passage. The turbine housing has a valve seat surface that is a flat surface that the wastegate valve contacts. The wastegate valve opens and closes the bypass passage. The wastegate valve has a valve surface that is a flat surface facing the valve seat surface. When the geometric center of the shape of an outer edge of the valve surface is called the valve center and the geometric center of the shape of an opening of the bypass passage in the valve seat surface is called the opening center, the shortest distance from the valve center to a central axis of the shaft is longer than the shortest distance from the opening center to the central axis of the shaft.
