US Patent 12012889 Turbocharger

A turbine housing has a scroll part, an outlet pipe, and an inlet pipe. A bypass passage is formed on an inner peripheral side of a twisting form leading from the inlet pipe toward the scroll part so as to allow communication between an inlet passage and an outlet passage. Viewing the turbine housing in an axial direction, an opening center of an outlet opening of the bypass passage is located in a quadrant where a mounting flange is located among four quadrants defined by a first imaginary plane that passes through a rotational center and that is parallel to a surface of the mounting flange, and a second imaginary plane that passes through the rotational center and that is orthogonal to the first imaginary plane.
