Abstract: A turbocharger (1) including a twin scroll turbine and a valve assembly (40, 140) disposed in the exhaust gas inlet (24, 124) that is configured to control the flow exhaust gas through the turbine. The valve assembly (40, 140) includes two rotary valves (60, 160, 80, 180) actuated by a common valve shaft (44, 144). One of the valves (60, 180) may control exhaust gas flow to a volute or between volutes, and the other (80, 160) may control wastegate exhaust gas flow. The valve shaft (44, 144) is driven by an actuator to rotate about the valve shaft rotational axis (46, 146) such that the first valve (60, 160) and the second valve (80, 180) can each be selectively moved between a closed position and an open position, and the time sequence order of opening of the first valve (60, 160) and the second valve (80, 180) is selectable.

Abstract: A rotary wastegate valve (48) includes a valve seat (50) having an opening (58), a valve shaft (80) that extends in a direction normal to a surface of the valve seat (50) and is offset relative a valve plate centroid (C), and a valve plate (90) driven by the valve shaft (80) to rotate relative to the valve seat (50). Rotation of the valve shaft (80) moves the valve plate (390) between a first position in which the valve plate (390) overlies the opening (58) and closes the opening (58), and a second position in which the opening (58) is at least partially open. The rotary wastegate valve (48) can be used to control exhaust gas flow through the turbine section (20) of an exhaust gas turbocharger (1).
