Beschreibung
Zusammenfassung:A turbocharger system is disclosed, including a turbine and compressor and a rotary valve unit. The rotary valve unit comprises a fixed valve seat and a rotary 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. The valve unit includes a valve housing that defines a first flow passage and a second flow passage, and the valve member and valve seat are disposed in the second flow passage. A turbocharger system is also disclosed, including a turbine and compressor and the rotary valve unit. The rotary valve unit is coupled with the turbine such that exhaust gas that has passed through the turbine wheel is fed into the first flow passage of the rotary valve unit, and exhaust gas that has bypassed the turbine wheel is fed into the second flow passage of the rotary valve unit.
