ABSTRACT:
A scroll compressor comprises a compression mechanism comprising a combination of a fixed scroll and an orbiting scroll; a main shaft for driving the orbiting scroll; an electric motor rotor and stator for driving the shaft; a first bearing frame for supporting the orbiting scroll in the axial direction through a bearing; a second bearing frame for supporting the shaft in the radial direction through a bearing; a hermetic shell including the compression mechanism in an upper portion, the rotor and stator in a lower portion, and an suction pipe for inspiring a working fluid; and a dividing chamber arranged in the shell so as to communicate with the suction pipe and having efflux holes for directing the inspired working fluid to the compression mechanism in the upper portion, the stator and rotor in the lower portion, and an upper coil end of the stator placed in a position lateral to the chamber.
