Abstract
A variable turbine geometry (VTG) turbocharger is disclosed. The VTG turbocharger may comprise a turbine section having a turbine wheel and plurality of guide vanes configured to regulate a flow of exhaust gases to the turbine wheel. The VTG turbocharger may further comprise an actuation pivot shaft (APS) configured to mediate actuation of opening and closing of the guide vanes, a bushing rotatably supporting the APS with a clearance therebetween, and a radial seal circumscribing the APS and inserted in a cavity of the bushing. The radial seal may form an interference fit with both an outer diameter of the APS and an inner diameter of the bushing to seal a leakage of the exhaust gases between the clearance between the APS and the bushing.
