A rotary compressor has a cylinder (21) having an annular cylinder chamber (50), an annular piston (22) received in the cylinder chamber (50) so as to be eccentric relative to the cylinder (21) and partitioning the cylinder chamber (50) into an outer compression chamber (51) and an inner compression chamber (52), a blade (23) placed in the cylinder chamber (50) and partitioning each of the compression chambers (51, 52) into the high-pressure side and the low- pressure side, and a compression mechanism (20) where the cylinder (21) and the piston (22) rotate relative to each other to compress a refrigerant. The outer compression chamber (51) is constructed as the low- stage side compression chamber (51) for compressing a low-pressure fluid into an intermediate-pressure fluid. The inner compression chamber (52) is constructed as the high-stage side compression chamber (52) for compressing the intermediate- pressure fluid compressed in the low-stage side compression chamber (51) into a high-pressure fluid. ® KIPO & WIPO 2007
