Abstract

A scroll compressor with high efficiency is provided according to the present invention. The scroll compressor compresses a refrigerant by meshing of an orbiting scroll (8) and a fixed scroll (7), wherein the orbiting scroll (8) includes a back pressure hole (35) which intermittently connects a compression chamber (13) and a back pressure chamber (18) per one orbit of the orbiting scroll (8), and the back pressure hole (35) communicates with the compression chamber (8) and also with the back pressure chamber (18) and shuts off the communication with the back pressure chamber (18) after the communication with the compression chamber (8) is shut off Fig. 1
