(54)	Scroll compressor and refrigerating machine having the same

(57) A scroll compressor and a refrigerating machine including the scroll compressor are provided. An oil supply channel may be formed in a fixed scroll of the compressor so as to provide for communication between a back pressure chamber and compression chambers formed between the fixed scroll and an orbiting scroll. The oil supply channel enables oil to be smoothly introduced from the back pressure chamber into each compression chamber, so that frictional losses and refrigerant leakage in the compression chambers may be effectively prevented, and efficiency of the compressor and the refrigerating machine including the compressor may be enhanced.
