Beschreibung
Zusammenfassung:	A vane carrier (10) for a compressor or a turbine section of an axial turbo machine, especially one of a gas turbine, steam turbine, compressor, expander, comprises least a first and second functional means (11, 12), whereby said first functional means (11) is a cylinder made of a material with a coefficient of thermal expansion (CTE) below 1.3*10 -5[1/K], which cylinder is provided for carrying a plurality of vanes on its inner side, and whereby said second functional means (12) is a support structure made of a material different to and less expensive than the material of said first functional means (11), which support structure (12) is provided for defining an axial and lateral position of said first functional means (11) within an outer casing (18) of said axial turbo machine. The advantage is a reduced clearance at moderate cost.
