Abstract

The guide blades provided for the variable turbine geometry are adjustably arranged within a radial gap through which gases can flow on a moveable carrier ring, which is axially clamped against stops on or in the radial gap with a thrust spring device. According to the invention, the thrust spring device loads the carrier ring on the positions closely adjacent to the stops. The thrust spring device is designed open without sealing function and if applicable combined with a separate seal without thrust function.
