Abstract

Charging equipment is disclosed, comprising a variable turbine geometry, and a plurality of guide vanes rotatably mounted between at least one of a guide vane carrier, a cover disc and a turbine housing. The guide vane carrier is positioned on at least one of the cover disc and on the turbine housing by at least one spacer. The geometry has at least two different types of flow channels, a first flow channel wherein flow is influenced by the spacer, and a second flow channel wherein flow is not influenced by the spacer. The first flow channel guide vanes have a radial distance (R1) to a turbine wheel axis, and to a distance from an adjacent guide vane are configured and adjusted such that a gas flow from the first flow channel meeting the turbine wheel corresponds to a gas flow from the second flow channel meeting the turbine wheel.
