An assembly for an exhaust bypass valve of a two-stage turbocharger can include a first turbocharger stage; a second turbocharger stage; an exhaust bypass valve that includes an open state and a closed state; and a linkage mechanism that links the exhaust bypass valve to an actuator where the linkage mechanism includes a locked state for the closed state of the exhaust bypass valve.

Linkage for exhaust bypass valve of multi-stage turbocharger

A turbocharger includes a variable turbine nozzle defined between a nozzle ring and a pipe flange, and having a plurality of circumferentially spaced vanes rotatably mounted on the nozzle ring such that the vanes are pivotable. Each vane includes an airfoil section and a disk section rigidly affixed to an end of the airfoil section, the disk section being disposed against a face of the pipe flange, each disk section having a plurality of perforations extending axially therethrough. The pipe flange has a corresponding number of holes for each disk section of the vanes, the holes being positioned such that as each vane is rotated the perforations in the disk sections and the holes in the pipe flange of the insert become aligned in some positions of the vanes, allowing exhaust gas to pass between the nozzle and a space on an opposite side of the pipe flange from the nozzle.

A turbine assembly for a turbocharger can include a C-shaped seal that includes an inner diameter, an outer diameter, an axis aligned parallel to a rotational axis of a turbine wheel, a lower lip that contacts a lower axial face of an outer surface of a shroud component along an annular portion of the shroud component, an upper lip that contacts a lower axial face of an inner surface of a turbine housing, and a wall portion that extends between the lower lip and the upper lip. Various other examples of devices, assemblies, systems, methods, etc., are also disclosed.
