摘要： A turbine housing includes a wastegate chamber with a wastegate opening; and a wastegate disposed in the wastegate chamber where the wastegate includes a plug configured to plug the wastegate opening and where the plug includes a surface; a shaft configured for receipt by a bore in a wall of the wastegate chamber; and a rotatable arm extending from the shaft where the arm has a surface configured for contacting the surface of the plug for a closed orientation of the plug with respect to the wastegate opening to transmit force from the arm more centrally to the plug. Various other examples of devices, assemblies, systems, methods, etc., are also disclosed.

摘要： A turbocharger includes a turbine wheel mounted within a turbine housing and connected to a compressor wheel by a shaft. The turbine housing defines an exhaust gas inlet connected to a divided volute that surrounds the turbine wheel, and an axial bore through which exhaust gas that has passed through the turbine wheel is discharged from the turbine housing. The turbine housing further defines a pair of concentric annular bypass passages surrounding the bore and arranged to allow exhaust gas to bypass the turbine wheel as two separate bypass streams. An annular bypass valve is disposed in the bypass passage. The bypass valve comprises a fixed annular valve seat and a rotary annular valve member arranged coaxially with the valve seat. The valve member is disposed against the valve seat and is rotatable about the axis for selectively varying a degree of alignment between respective orifices in the valve seat and valve member.
