Abstract (en)

To provide a compressor capable of securing good lubrication by holding oil in a sealed space in a suitable amount to avoid oil shortage and suppressing the reduction of a shaft sealing function (oil leakage) due to the temperature increase in the shaft sealing member by promoting replacement of lubricating oil supplied to the shaft sealing member. In a compressor which includes, in a housing, an oil supply passage 32 one end of which communicates with a crank chamber 6 and the other end of which communicates with a sealed space 30 formed between a radial bearing 11 and a shaft sealing member 10 and an oil discharge passage 34 one end of which communicates with the sealed space 30 and the other end of which communicates with the crank chamber 6, an inflow port 34a opening to the sealed space of the oil discharge passage 34 opens to a position on an upper side of the lowest position at which the drive shaft 7 is in contact with the sealed member 10 as well as on the same position as a horizontal surface including an axial center "O" of the drive shaft 7 or on a lower side of the horizontal surface.
