SCROLL COMPRESSOR

摘要

A scroll compressor includes a back pressure chamber oil-feeding path 25 for feeding lubricating oil 7 from a high-pressure region 21 to a back pressure chamber 22, and a compression chamber oil-feeding path 26 for feeding lubricating oil 7 from the back pressure chamber 22 to a compression chamber 10. One phase in which the back pressure chamber oil-feeding path 25 is communicated from the high-pressure region 21 to the back pressure chamber 22 and another phase in which the compression chamber oil-feeding path 26 is communicated from the back pressure chamber 22 to the compression chamber 10 are shifted from each other, so that the back pressure chamber oil-feeding path 25 and the compression chamber oil-feeding path 26 are never put into the communicating state simultaneously. Thus, after a halt of the compressor, under-communication oil-feeding of the lubricating oil 7 from the high-pressure region 21 via the back pressure chamber 22 to the compression chamber 10 can be prevented, so that the lubricating oil 7 in the liquid storage section 6 is kept from decreasing and moreover the lubricating oil 7 is kept from being filled into the compression chamber 10, make it possible to achieve a stable restart-up.
