PROBLEM TO BE SOLVED: To provide a technology capable of reducing an amount of a lubricant mixed in a working medium discharged from a compressor.SOLUTION: A compressing mechanism portion 120 and a motor 140 are disposed in a sealed container 110. The motor 140 has a stator 150 and a rotor 160. A stator passage 170 is formed between an outer peripheral face of a stator core 151 of the stator 150 and an inner peripheral face 110a of the sealed container 110, and a rotor passage 180 is formed on a rotor core 162 of the rotor 160. The stator passage 170 is composed of a first passage part 170a, and a second passage part 170b disposed at a side opposite to the compressor mechanism portion 120 with respect to the first passage part 170a, and having a passage area wider than a passage area of the first passage part 170a. The rotor passage 180 is composed of a first passage part 180a, and a second passage part 180b disposed at a side opposite to the compressing mechanism portion 120 with respect to the first passage part 180, and having a passage area wider than a passage area of the first passage part 180a.SELECTED DRAWING: Figure 1 |
