摘要： 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.

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.

摘要： a First gap 15 in a thrust direction between teeth bottoms of a fixed mirror plate 2b and teeth tips of an orbiting lap 4a, and a second gap 16 in the thrust direction between teeth bottoms of an orbiting mirror plate 4b and teeth tips of a fixed lap 2a are formed such as to gradually increase from an outer peripheral side to an inner peripheral side of a scroll compressor, the first gap 15 is made greater than the second gap 16. Contact surface pressures of the laps 2a and 4a are kept low with respect to pressure deformation, contact pressure of the teeth tips of the fixed scroll part 2 and the teeth bottoms of the orbiting scroll part 4 are equally maintained. With this loads applied to the scroll parts 2 and 4 are equally received by a thrust surface.
