Abstract: A scroll compressor is provided. The scroll compressor includes a fixed scroll, an orbiting scroll configured to orbit with respect to the fixed scroll and including an orbiting end plate, and a main frame to which the orbiting scroll is coupled to orbit. The scroll compressor includes a compression chamber in which a refrigerant is compressed by the fixed scroll and the orbiting scroll, and a first back pressure chamber and a second back pressure chamber provided to communicate with the compression chamber. The first back pressure chamber and the compression chamber communicate with each other through a first flow path. The second back pressure chamber and the compression chamber communicate with each other through a second flow path. A different intermediate back pressure is formed in the first back pressure chamber and the second back pressure chamber.
