A structure for reducing a refrigerant flow loss in a compressor includes a refrigerant
flow resistance reducing unit to reduce a refrigerant channel resistance at a lower
surface of a rotor facing a compression mechanism unit. When the high temperature
and high pressure refrigerant gas discharged from the compression mechanism unit
flows to the discharge pipe through the refrigerant passage including the gap between
the rotor and the stator of the electric mechanism unit, the flow resistance of
the refrigerant gas is reduced. Therefore, since the refrigerant can flow smoothly,
a flow loss of the refrigerant can be reduced and, as a noise generation is reduced,
a reliability can be heightened.
