See full text

A compressor includes a casing, a motor fixed to the casing, a vertically extending drive shaft coupled to the motor, and a compression mechanism driven by the drive shaft to compress a fluid. A shaft-inside oil supply path is provided in the drive shaft. Oil at a bottom of the casing is supplied through the shaft-inside oil supply path to a sliding portion of the drive shaft above the motor. The compressor includes a shaft-inside oil discharge path provided in the drive shaft, and an oil discharge coupled to a lower end of the drive shaft. The shaft-inside oil discharge path extends from an upper portion to a lower portion of the motor. The oil discharge pump discharges the oil that has been supplied to the sliding portion of the drive shaft to the bottom of the casing through the shaft-inside oil discharge path.
