OIL SUPPLY STRUCTURE OF HIGH-PRESSURE TYPE SCROLL COMPRESSOR

摘要

An oil supply structure of a high pressure type scroll compressor is provided to form an oil supply groove at an indent groove for supplying lubrication oil to compression chambers always, thereby reducing mechanical friction heat of the compression chambers to prevent temperature rising of the compression chambers and improving reliability of the compressor performance. An oil supply structure of a high pressure type scroll compressor includes an upper frame(120) formed with an indented groove(123) in the annular shape for inserting a seal ring which blocks a gap between the upper frame and an orbiting scroll(150). An oil supply groove(125) is formed in an outer surface of the indented groove for supplying a predetermined amount of lubrication oil to compression chambers(P) via an oil supply path of the seal ring always.
