An internal oil separator for compressors of refrigeration systems is disclosed. This oil separator supplies an effective quantity of lubrication oil to the drive parts of a compressor, and protects the compressor from being unexpectedly damaged or locked. The oil separator accomplishes the recent trend of compactness of compressors, and prevents a bypass flow of the compressed refrigerant into the compressor. This oil separator collaterally reduces operational noises of the compressor. In this oil. separator, an oil-separating chamber 21, having a generally U-shaped passage, is defined in the rear section of a compressor housing by a cover 2. The oil-separating chamber 21 has a guide wall 22, thus forming a desired U-shaped passage therein. Refrigerant inlet and outlet ports 13, 14 are formed on the rear wall of the housing. An oil-collecting part 17 is formed on the bottom of the oil- separating chamber 21 and stores recovered oil therein. This oil-collecting part 17 communicates with an oil return line 16 through an oil return channel 31 of a gasket 3, and so the recovered oil returns to the driving part chamber 18 of the compressor. The above gasket 3 is interposed between the housing 1 and the cover 2, thus accomplishing a desired sealing effect. An oil-separating plate 4 and/or a screen member 5 formed by single loop structure is preferably set within the oil-separating chamber 21.
