Abstract
The disclosure illustrates a turbocharger comprising a radially inward flow turbine and a vaned inlet turbine nozzle. A variable inlet area is provided by an annular control ring continuous at its inner diametrical face and having slots extending inward from its radially inner portion of the vanes. The control ring may be attached to a steel stamping which, in turn, is attached to shafts of a pair of actuators for axially displacing the control ring and thus varying flow area through said turbine nozzle. By only partially embracing the inlet canes, the possibility of sticking due to carbon build-up is minimized if not eliminated.
