PROBLEM TO BE SOLVED: To provide a compressor lubricating system capable of securing stable supply of a lubricant to a compressor and dissolving lubrication shortage in a crank chamber. SOLUTION: This compressor lubricating system 101 comprises the compressor 1 comprising the crank chamber 15 inside, an oil separator 41 and an ejector 61. A supply port 61a of the ejector 61 is communicated with a discharge port 26 of the compressor 1, the discharge port 61b is communicated with the crank chamber 15 of the compressor 1, and a suction port 61c is communicated with the oil separator 41. The ejector 61 sucks the lubricant separated from a refrigerant by the oil separator 41, from the suction port 61c by action of negative pressure generated inside of the ejector 61 in circulating the refrigerant discharged from the compressor 1 from the supply port 61a to the discharge port 61b, mixes the refrigerant and the lubricant, and supplies them to the crank chamber 15 through the discharge port 61b.
