Title:
SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2015/155798
Kind Code:
A1
Abstract:
There is demand for a scroll compressor that prevents an excessive amount of oil from being supplied during high-speed operation, enables a sufficient amount of oil to be supplied during low-speed operation, and does not cause fluctuations in the oil supply amount regardless of the presence of play. This scroll compressor (100) comprises: a main body vessel (1); a fixed scroll (9); an orbiting scroll (10); a rotary drive shaft (4) having an oil passage hole (4c); a frame (11); a ring-plate-shaped thrust plate (14) disposed between the orbiting scroll (10) and the frame (11); and an oil pump (22) for delivering a lubrication oil (Y). Some of the lubrication oil (Y) delivered into a recessed part (11b) of the frame (11) from the oil passage hole (4c) of the rotary drive shaft (4) flows to spiral teeth (10a) of the orbiting scroll (10) after passing between the orbiting scroll (10) and the thrust plate (14) and between the orbiting scroll and the frame (11). An oil passage groove (40) for connecting the inner peripheral surface (14b) of the thrust plate (14) to the outer peripheral surface (14c) is formed on the upper surface (14a) of the thrust plate (14).
