Abstract
A turbocharger system includes a valve member disposed between plural volute passages of a turbine section and a wastegate. The valve member is supported for rotation about an axis of rotation between various positions. The valve member, in a first position, provides a cross flow path between the first volute passage and the second volute passage and provides a bypass flow path from at least one of the first and second volute passages to the wastegate. In a second position, the valve member provides the cross flow path and substantially prevents flow along the bypass flow path. In a third position, the valve member substantially prevents flow along the cross flow path and the bypass flow path. The valve member includes at least internal one valve passage and plural apertures that fluidly connect or alternatively fluidly disconnect the volute passages and wastegate in the first, second, and third positions.
