  • Patent number: 8702381
    Abstract: The flow path of exhaust gas to the turbine wheel (70) of a turbocharger is influenced by relative motion between two rings of vanes, at least one of which being provided on a vane ring. The outer ring of vanes contains a plurality of vanes (92, 122), the inner ring of vanes contains a plurality of vanes (93, 121), and the inner and outer vanes in registry forming a single generic vane shape. The aerodynamic effect of relative displacement of the outer ring of vanes to the inner ring of vanes produces a modulate-able control of exhaust flow to the turbine wheel.

  • Patent number: 8616837
    Abstract: A vane ring assembly which includes a lower vane ring (22), an upper vane ring (30), one or more guide vanes (80) positioned at least partially between the vane rings, and a plurality of spacers (42, or 50) positioned between the lower and upper vane rings for maintaining a distance between the lower and upper vane rings.

  • Patent number: 8545173
    Abstract: A process for calibrating a variable-nozzle assembly (200) prior to its installation in a turbocharger. The variable-nozzle assembly facilitating such process is installed in a calibration fixture (20) having internal flowpath contours configured to replicate corresponding internal flowpath contours of a turbocharger into which the variable-nozzle assembly (200) is to be installed. The calibration fixture (20) defines a generally annular chamber (110) in fluid communication with a flow path defined in the variable-nozzle assembly (200), and a fluid supply passage (112) extending into the annular chamber. A fluid is supplied through the fluid supply passage (112), and the fluid then flows through the flow path of the variable-nozzle assembly (200). While the fluid is flowing through the variable-nozzle assembly (200), the vanes (220) are pivoted to set a predetermined flow rate.

  • Patent number: 8545172
    Abstract: A turbocharger with a variable nozzle includes a pin mounted in the center housing and extending axially therefrom and engaged in a hole in the nozzle ring to orient the nozzle ring rotationally relative to the center housing. A portion of a length of the pin has a substantially greater compliance than the remainder of the length such that the pin has a flexible tip that engages the hole in the nozzle ring. The flexible tip reduces constraint of thermal deformation of the nozzle ring. The pin portion of greater compliance can be a section of the tube that is slit and expanded. The turbocharger can also include a one-piece locator and heat shield having a locating portion abutting the center housing and the nozzle ring for radially locating the nozzle ring relative to the center housing, and having a shield portion shielding the center housing from hot exhaust gas.

    Abstract: A variable geometry turbocharger assembly comprises a unison ring which rotates about a longitudinal axis defined by a shaft on which a turbine wheel and compressor wheel are attached in order to pivot a plurality of vanes and thereby control a flow of exhaust gas to the turbine wheel. The unison ring rotates on at least one guide pin which is secured to the turbocharger. The guide pins may be press-fit into apertures in a center housing at an outer pilot surface. In other embodiments the guide pins may be press-fit into a different part of the turbocharger such as a nozzle ring.
