Abstract
A scroll compressor including an orbiting scroll that performs an orbiting motion; a fixed scroll coupled to the orbiting scroll so as to form a compression chamber; and a main frame that rotatably supports the orbiting scroll at an opposite side of the fixed scroll with the orbiting scroll interposed therebetween, and supportably connected to the fixed scroll. The fixed scroll is provided with a back pressure hole formed between a first back pressure chamber in which gas discharged from the compression chamber is received, and the compression chamber. The back pressure hole may communicate with the first back pressure chamber and the compression chamber on the basis of a predetermined pressure ratio of the compression chamber.
