Abstract
A scroll compressor includes a sealed container, a compression mechanism portion for a refrigerant, a compliant frame and a guide frame which support an orbiting scroll, an electric motor which drives the orbiting scroll, balance weights, a refrigerant flow path which introduces a refrigerant gas discharged through a discharge port of a fixed scroll to a bottom portion of the sealed container, cup-shaped members provided on both upper and lower surfaces of the rotor of the electric motor and contain the balance weights, a penetrating flow path through which the refrigerant gas containing a refrigerating machine oil 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 which is provided at a lower portion of the frame, and which introduces the refrigerant gas to a discharge pipe.
