Abstract: A variable turbine geometry assembly is provided for controlling flow of exhaust gas to a turbine wheel of a turbocharger. The variable turbine geometry assembly includes a base structure, vanes, vane levers, and an adjustment ring. The vanes are distributed circumferentially around the base structure and are pivotable relative to the base structure to vary an effective inlet area. The vane levers are for pivoting the vanes. The vane levers each include an inner portion coupled to one of the vanes and an outer portion extending from the inner portion. The adjustment ring is selectively rotatable about a central axis to pivot the vanes. The adjustment ring includes apertures that are each associated with and have received therein the outer portion of one of the vane levers. The outer portion of each of the vane levers includes an outer surface that is non-parallel with the central axis.

Abstract: A number of variations may include a method for increasing peak flow in a variable geometry turbine turbocharger comprising: by-passing fluid flow to a turbine impeller by forming at least one internal by-pass passage through at least one of a lower vane ring of a vane pack assembly or a turbine housing below the lower vane ring; providing a first end of a vane component within the at least one internal by-pass passage; and using the first end of the vane component as a rotary valve to control fluid flow through the at least one internal by-pass passage.

Abstract: A variable turbine geometry assembly includes an adjustment ring extending along and rotatable about an axis, at least one vane lever coupled to the adjustment ring, and at least one vane coupled to the at least one vane lever. The variable turbine geometry assembly also includes a biasing member coupled to the adjustment ring at a first circumferential location on the adjustment ring and coupled to the adjustment ring at a second circumferential location on the adjustment ring. The biasing member extends from the first circumferential location to the second circumferential location. The biasing member is operably in contact with the at least one vane lever between the first circumferential location and the second circumferential location to bias the at least one vane lever toward the adjustment ring and to reduce vibration between the adjustment ring and the at least one vane lever.

Abstract: A variable geometry turbine turbocharger (1) includes a gear driven adjustment ring actuator mechanism (300) supported within a housing (16) via a resilient mount (70) disposed between the mechanism (300) and housing (16). The gear driven adjustment ring actuator mechanism (300) rotates an adjustment ring (350), which in turn adjusts the position of the vanes (30) of the variable geometry turbine (2). The resilient mount (70) accommodates the heat-related expansion and contraction of the gear driven adjustment ring actuator mechanism (300).

Abstract: A variable turbine geometry turbine turbocharger (1) includes a vane pack (50) disposed in the exhaust gas path upstream of the turbine wheel (12). The vane pack (50) includes vanes (30) that are rotatably supported between a pair of vane rings (34) and configured to adjustably control the flow of exhaust gas to the turbine wheel (12). In addition, a retainer (60, 160) secures the vane pack (50) to the bearing housing (16) in such a way that the vane pack (50) is mechanically decoupled from the turbine housing (4).
