  • Patent number: 5947681
    Abstract: A turbocharger with a variable turbine nozzle having a plurality of vanes provides reduced actuation forces by pressure balancing the vane support axles. A nozzle ring and insert ring are secured in substantially rigid spaced relation by a series of hollow spacers and bolts to position the vanes between the nozzle inlet from the volute and nozzle outlet adjacent the turbine. A chamber intermediate the turbine housing and the center housing of the turbocharger accommodates the actuation mechanism for the nozzle vanes and through communication with the nozzle inlet from the volute by the tolerances between the nozzle ring and various elements of the actuation linkage transmits exhaust gas pressure to impinge on an end of the first axle for each vane. Balancing exhaust gas pressure is transmitted through channels between the turbine housing and insert ring, which extend from the nozzle inlet to the apertures receiving the second axles, to impinge on an end of the second axle for each vane.
