Abstract

A turbocharger device includes an annular spring element for axially clamping a guide device of a variable turbine geometry against a turbine housing. The annular spring element rests radially outwardly on the bearing housing and radially inwardly on a component of the guide device. The spring element has an annular radial outer flange in contact with the bearing housing, and a plurality of tabs which extend from the outer flange radially inwardly in the direction of the guide device and come into contact with a component thereof. An annular spring element for such a turbocharger is also provided.
