Title:
SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2019/225191
Kind Code:
A1
Abstract:
In order that operating efficiency of a scroll compressor (1) is suppressed from lowering by suppressing a lubricant oil in an annular space (45) between an outer peripheral wall (37) of a housing (30) and an Oldham ring (70) from becoming resistance against motion of the Oldham ring (70) when a movable scroll (60) makes eccentric rotation, a space communication part (40) is formed in the housing (30). The space communication part (40) discharges the oil from the annular space (45) between the Oldham ring (70) and the outer peripheral wall (37) positioned in a periphery of the Oldham ring (70) to an oil discharging space (46) between a fixed scroll (50) and a Oldham ring supporting surface (36) of the housing (30).
