摘要： PROBLEM TO BE SOLVED: To solve the problem in a conventional compressor that the pressure of the upper space of an electric motor often becomes lower than the pressure of the lower space depending on an operating condition, and in this case, a main spindle is vertically moved with a rotor because of the vertical pressure difference of the rotor to generate a foreign sound or damage a rocking shaft by the wear of the upper end of the main spindle. SOLUTION: This compressor comprises a compression mechanism housed in a sealed casing to compressively discharge a coolant sucked from the outside of the sealed casing into the sealed casing; an electric motor housed in the sealed casing, comprising a stator and the rotor to drive the compression mechanism through the main spindle; and a fan provided between the rotor and the compression mechanism to generate a cold inward flow according to the rotation of the main spindle.

摘要： PROBLEM TO BE SOLVED: To provide a scroll compressor including a compliant frame 3 movable in the axial direction while it supports a swinging scroll 2, in which there is such problems according to the conventional technique that the engaging parts of the compliant frame 3 and a guide frame 4 therefor are easily worn abnormally due to sliding when the compliant frame 3 guided by the guide frame 4 moves in the axial direction and that deterioration is likely in a refrigerator oil due to a rise of the temperature. SOLUTION: The scroll compressor is configured so that an opening in a shaft oiling passage 5b formed in the main shaft 5 is put in communication intermittently with an opening in a frame oiling passage 3u formed in the compliant frame 3, and thereby it is practicable to supply a proper quantity of oil.
