PURPOSE:To provide stable bearing performance even during high speed rotation by controlling the temperature of a magnetic bearing part without lowering the efficiency of a turbine. CONSTITUTION:In a turbine compressor supported by magnetic bearings 3a, 3b, and 4, lines 9 and 10 are provided, a regulating valve 8 arranged on the lines, and a thermometer 11 and a regulating valve 13 for a pressure in a bearing chamber are arranged at a bearing part so that process gas boosted by a compressor impeller 5 is guided to the back of a compressor impeller 5 and a magnetic bearing part. |
