| 摘要 | A hybrid compressor having a first compression mechanism driven only by an outside drive source; a second compression mechanism driven only by a built-in electric motor; suction paths for sucking a gas to be compressed, into the first compression mechanism; communication paths for sucking the gas from the first compression mechanism side into an electric motor side suction chamber; and suction paths for sucking the gas from an electric motor side suction chamber to the second compression mechanism side. The positions and/or the number of the communication paths and/or the suction paths, and/or the positions and/or the number of communication openings and/or suction openings are limited for at least a portion of the gas sucked into the electric motor side suction chamber via the communication paths, where the communication openings are openings of the communication paths and opened at the electric motor side suction chamber and where the suction openings are openings of the suction paths, opened at the electric motor side suction chamber, and located on the opposite side of the communication openings. As a result, a gas flow is formed from the communication openings to the suction openings. A built-in electric motor section can be appropriately cooled in a wide range by a suction gas, so that a rise in temperature in the motor section can be suppressed. | ||||||
