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