Abstract

A turbo compressor in which a rotor having impellers is supported by a magnetic bearing is constructed such that a control valve is provided in a thrust balancing line connecting a suction line of the compressor to a balancing chamber formed outside a balancing drum provided at one end side of a rotor. The control valve serves to regulate a rate at which a gas flows through the thrust balancing line, and is adapted to be controlled in relation to a load imposed upon the magnetic thrust bearing.
