Abstract
The present disclosure relates to an exhaust gas turbocharger, for example for a motor vehicle. The exhaust gas turbocharger includes a turbine including a turbine housing and a turbine wheel, a variable turbine geometry including a vane ring and at least one adjustable guide vane, and a spring arrangement including a disc spring structured and arranged to mechanically impact the vane ring in a direction of the turbine housing. The disc spring extends in a circumferential direction with respect to a rotary axis of the turbine wheel and comprises a disc opening that extends up to a radial inside of the disc spring. A heat shield of the spring arrangement extends in the circumferential direction and is arranged on a side of the disc spring axially facing towards the vane ring.
