Title:
COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2013/172002
Kind Code:
A1
Abstract:
This compressor is provided with oil separation mechanism sections (40) which separate oil from a refrigerant gas discharged from a compression mechanism section (10), the oil separation mechanism sections (40) each having: a cylindrical space (41) for swirling the refrigerant gas; an inlet section (42) for allowing the refrigerant gas discharged from the compression mechanism section (10) to flow therefrom into the cylindrical space (41); a delivery opening (43) for delivering the refrigerant gas, from which the oil has been separated, into one in-container space (31) from the cylindrical space (41); and a discharge opening (44) for discharging the separated oil and a part of the refrigerant gas from the cylindrical space (41) into the other in-container space (32). Also, if the cylindrical space (41) includes a projection of the delivery opening (43), the diameter of the cylindrical space (41) is Do, and the width of the inlet section (42) is W, the expression Do/2 > W is satisfied, and this makes an electric motor section (20) highly efficient, improves the volumetric efficiency, and reduces the amount of oil circulation.
