Title: SCROLL COMPRESSOR
Abstract:
This scroll compressor can adjust intermediate pressure to a prescribed pressure during compression of a compression chamber 15 and reduce the compression ratio under low compression ratio conditions in which an orbiting scroll 12 separates from a fixed scroll 11, by: providing, in a fixed scroll end plate 11a, an intermediate pressure extraction hole 41 that takes out intermediate pressure from the compression chamber 15; forming, in the fixed scroll 11, an intermediate pressure communication path 42 that connects the intermediate pressure extraction hole 41 and an intermediate pressure region B; forming a high pressure communication path 71, in the fixed scroll 11, that connects the intermediate pressure extraction hole 41 and a high pressure space inside a sealed container 1; and providing a balance valve 73 in a high pressure opening 72 of the high pressure communication path 71.
