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.
