Patent Searching and Data

Document Type and Number:
WIPO Patent Application WO/2019/102673
Kind Code:
This compressor is provided with: a container having an oil holding section; a compression mechanism disposed within the container and compressing a refrigerant; a centrifugal separation section for separating oil from the compressed refrigerant; discharge piping for discharging to the outside of the container, the refrigerant having been subjected to the separation by the centrifugal separation section; and an oil collection section provided outside the centrifugal separation section and collecting the separated oil. The centrifugal separation section has: a cylinder having a plurality of holes in the side surface thereof; and a swirl mechanism provided inside the cylinder and ejecting the refrigerant compressed by the compression mechanism, thereby forming a swirl flow flowing toward the discharge piping while swirling inside the cylinder. Oil is separated from the refrigerant by the centrifugal force of the swirl flow, and the separated oil is discharged to the outside of the cylinder through the holes. As a result, the oil separated from the refrigerant is prevented from dispersing, and the amount of oil discharged to the outside of the compressor can be reduced.
