Title:
COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2019/017144
Kind Code:
A1
Abstract:
Provided is a compressor which enables reliable separation of oil from a refrigerant gas while suppressing increases in the size of equipment and manufacturing costs. This compressor (1) is provided with: a housing (2); a compression mechanism (13) which compresses a refrigerant gas flowing into an intake space (Ss); an oil separation space (So) which separates oil from the refrigerant gas compressed by the compression mechanism (13) and guides the oil to a discharge pipe (40); and a separation cylinder (30) which is disposed along an axial line (X2) of the oil separation space (So) over the oil separation space (So) in the gravitational direction. The separation cylinder (30) has a small-diameter section, and a large-diameter section formed under the small-diameter section in the gravitational direction; the oil separation space (So) has a separation section in which the small-diameter section and the large-diameter section are disposed, and which has a first inner diameter larger than a second outer diameter of the large-diameter section, and an oil storage section disposed under the separation section; and the refrigerant gas compressed by the compression mechanism (13) flows into the separation section.
