Patent ID: 8328503

Claim:
A piece of charging equipment, comprising: a variable turbine geometry, and a plurality of guide vanes rotatably mounted between a guide vane carrier and at least one of a cover disc and a turbine housing, wherein the guide vane carrier is positioned on at least one of the cover disc and on the turbine housing by at least one spacer, wherein the variable turbine 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, wherein the guide vanes in the first flow channel are shaped to have a radial distance (R 1 ) 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, and wherein the guide vanes in the first flow channel have a different distance (R 1 ) to the turbine wheel axis than the guide vanes in the second flow channel.
