Abstract
A centrifugal compressor of the type in which disassembly and assembly of the compressor is effected by taking out and inserting internal component parts including end walls for closing ends of a cylindrical rotor chamber wall from and into a cylindrical rotor chamber in the axial direction thereof, including intake chamber side communication holes communicating with an intake chamber formed within the cylindrical rotor chamber and a propelling force balance chamber side communication hole communicating with a propelling force balance chamber formed within the cylindrical rotor chamber. The intake chamber side communication holes are formed in the internal component part and in the cylindrical rotor chamber wall, respectively. The propelling force balance chamber side communication holes are respectively provided in an inner axial end surface of the cylindrical rotor chamber wall and an end wall removably fitted in the cylindrical rotor chamber wall with a portion of the end wall abutting the inner axial end surface of the cylindrical rotor chamber wall. The intake chamber side communication hole and the propelling force balance chamber communication hole provided in the cylindrical rotor chamber wall are communicated with each other through a balance pipe mounted on an outer surface of the cylindrical rotor chamber wall.
