  • Patent number: 12196208
    Abstract: A compressor includes a tubular shape casing, a compression mechanism adjacent one end of the casing in the casing, a motor arranged adjacent another end of the casing in the casing, a suction pipe opening between the compression mechanism and the motor, a gas flow path formed between the motor and an inner peripheral surface of the casing, and a gas guide facing an open end of the suction pipe. The gas flow path allows internal regions of the casing adjacent axial ends of the motor to communicate with each other. The gas guide includes a first flow path configured to guide a portion of a gas that has passed through the suction pipe toward the compression mechanism, and a second flow path configured to guide a remaining portion of the gas that has passed through the suction pipe toward the gas flow path.
