Title:
SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2022/158519
Kind Code:
A1
Abstract:
This scroll compressor (10) comprises a valve mechanism (90) that opens and closes a second oil supply passage (82). The valve mechanism (90) has a valve (92) that divides the second oil supply passage (82) into a first space (S1) and a second space (S2). The pressure in the first space (S1) is equivalent to the discharge pressure of a compression mechanism (40). The second space (S2) communicates with a groove (41). As the pressure in the first space (S1) relative to the second space (S2) decreases, the valve (92) moves from a first position at which the second oil supply passage (82) is closed to a second position at which the second oil supply passage (82) is opened.
