Abstract: A scroll compressor and a refrigerating machine including the same are provided. In the scroll compressor, an oil supply hole formed in an orbiting scroll guides oil from a space between a frame and the orbiting scroll to a space between a fixed scroll and the orbiting scroll, and an oil supply groove formed at the fixed scroll maintains communication with the oil supply hole, thereby rapidly supplying oil to a bearing surface between the fixed scroll and the orbiting scroll before the oil is introduced into a back pressure chamber. This enhances compressor efficiency by effectively preventing frictional losses and refrigerant leakage in such a compressor, and enhances energy efficiency for a refrigerating machine using such a compressor.
