摘要：A hybrid compressor has a first compression mechanism driven only by anexternal drive source; a second compression mechanism driven only by a built-in electricmotor; suction paths for sucking gas to be compressed into the first compressionmechanism; communication paths for sucking the gas from the first compression

mechanism side into an electric motor side suction chamber; and suction passageways forsucking the gas from the electric motor side suction chamber to the second compressionmechanism side. The positions and/or number of the communication paths and/or thesuction passageways, and/or the positions and/or number of communication openings,which are openings of the communication paths and opened at the electric motor sidesuction chamber, and/or suction openings, which are openings of the suction

passageways, opened at the electric motor side suction chamber, and located on a sideopposite to the side of the communication openings, are limited so that, with respect toat least a part of the gas sucked into the electric motor side suction chamber via thecommunication paths, a gas flow is formed from the communication openings to thesuction openings. In this structure, a built-in electric motor section can be appropriatelycooled over a wider area by the sucked gas, so that a rise in temperature of the motorsection can be properly suppressed.
