Abstract
A turbocharger with variable geometry turbine inlet nozzle employs a rotating unison ring for actuation of multiple vanes. A crank arm engages a slot in the unison ring to convert linear actuator motion into rotation of the unison ring. A crank pin having a rectangular tongue adapted to be received in the slot and a circular body received in an aperture in the crank arm reduces contact stresses between the crank tongue and unison ring slot. The crank pin is retained in the crank arm by the unison ring and center housing flange of the turbocharger.
