ABSTRACT:
Exemplary vanes for a turbocharger having variable nozzle geometries are disclosed. In one aspect, each of the vanes includes two axial surfaces that are on opposite sides of the vane. The opposite axial surfaces include two corresponding chambers. These chambers are partially exposed to each other through an aperture. Such an aperture allows for some degree of equalization of the pressures in the chambers and, thereby, reduces the axial load exerted by a vane, for example, on the unison ring. In another aspect, each of the vanes includes two opposite airfoil surfaces. At least one of the airfoil surfaces includes a notch that allows a chamber in the nozzle to be pressurized by the exhaust gas. The pressure in the chamber creates a counteracting force that reduces the axial load exerted by a vane.
