Abstract
A turbocharger system includes a valve member with at least one valve passage. The valve member is supported for rotation about an axis of rotation between a first position, a second position, and a third position. The axis of rotation is oriented transverse to flow within a first volute passage and a second volute passage. The valve passage, with the valve member in the 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 and a bypass passage. In the second position, the valve passage provides the cross flow path, and the valve member substantially prevents flow along the bypass flow path. The valve member, in the third position, substantially prevents flow along the cross flow path and the bypass flow path.
