A scroll compressor 100 includes a sealed container 10, a compression mechanism portion 14 for a refrigerant, a compliant frame 3 and a guide frame 4 which support an orbiting scroll 2, an electric motor 5 which drives the orbiting scroll, balance weights 15a and 15b which are fixed to both upper and lower surfaces of a rotor 5a of the electric motor, a refrigerant flow path 30 which introduces a refrigerant gas discharged through a discharge port 1 d of a fixed scroll 1, to a bottom portion of the sealed container, cup-shaped members 17 and 18 which are provided on both upper and lower surfaces of the rotor of the electric motor and contain the balance weights, a penetrating flow path 5f through which the refrigerant gas containing a refrigerating machine oil 11 flows from a lower side of the rotor of the electric motor through the interiors of the cup-shaped members to an upper side of the rotor, and a discharge cover 16 which is provided at a lower portion of the frame, has an opening 16b opposed to an opening 17a of the first cup-shaped member 17 provided on the upper surface of the rotor of the electric motor, and introduces the refrigerant gas having passed through the penetrating flow path, to a discharge pipe 12. |
