Zusammenfassung:	PURPOSE: A refrigerator is provided to evenly maintain amount of oil between a first compressor and a second compressor because an oil balancing pipe is installed between the first and second compressors and an oil balancing valve is installed in the middle of the oil balancing pipe. CONSTITUTION: A refrigerator comprises multiple compressors(11,12), an oil balancing pipe(21), and an oil balancing valve(22). A discharged port of a first compressor connecting to a condenser is connected to a suction port of a second compressor and compresses the refrigerant in multistage. The oil balancing pipe is installed between the first and second compressors and oil in each compressor moves through thereof. The oil balancing valve is installed in the oil balancing pipe to open and close the oil balancing pipe.
