  • Patent number: 10240518
    Abstract: A variable-geometry turbocharger (1) with a vane lever (11) that provides a stop function at full open position of the guide vanes (8). The integrated vane-open stop controls the full open position of the VTG mechanism. A vane lever (11) preferably has an integrated protrusion (50) that functions as a vane-open stop that contacts an adjacent vane lever (11), an integrated bolt (56), or the upper vane ring (16) at the full open position to regulate maximum exhaust gas flow to the turbine wheel (5).
    Type: Grant
    Filed: March 12, 2014
    Date of Patent: March 26, 2019
    Assignee: BorgWarner Inc.

  • Patent number: 9217330
    Abstract: A product for balancing a shaft and wheel assembly of a turbocharger is disclosed. A fixture may have an exterior surface, with an aperture extending through the exterior surface. A first conduit may extend through the fixture and may exit from the first conduit through the exterior surface. A second conduit may extend through the fixture and may exit into the aperture. A pressurized gas source may be connected to the first and second conduits. An electromagnet may be positioned in the fixture and may extend around the aperture. The pressurized gas source may be operated to apply pressurized gas through the first and second conduits and the electromagnet may be operated to apply a magnetic field to the aperture.
