Title:
COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2021/015115
Kind Code:
A1
Abstract:
The present invention addresses the problem of increasing the rate of separation of lubricating oil in a compressor equipped with a centrifugal separating-type oil separator. A scroll compressor 100 is provided with a scroll unit 120 which draws, compresses, and ejects a gaseous refrigerant as a compressive fluid, and an oil separator 230 which separates lubricating oil from the gaseous refrigerant ejected from the scroll unit 120. The oil separator 230 comprises: a separating chamber H6 for separating the lubricating oil from the gaseous refrigerant using a centrifugal force; an oil storage chamber H7 positioned under the separating chamber H6 to store the lubricating oil separated in the separating chamber H6; and a partitioning plate 230C disposed so as to partition the separating chamber H6 and the oil storage chamber H7 from each other. The partitioning plate 230C has a plurality of communication holes 230C1 formed along the circumferential direction. The communication holes 230C1 have an inclined surface opposite the gaseous refrigerant turning in the separating chamber H6.
