A 2-stage rotary compressor is provided to simplify the sealing, opening and fixing of an injection pipe by forming a cutting part at an end of the injection pipe. An injection pipe(153) is connected to an intermediate path outside a sealed container(101) for introducing refrigerant of high pressure into the intermediate path, wherein the injection pipe is formed with a relatively thin cutting part at an end which is positioned outside the sealed container. The intermediate path is an internal path(180) for moving primarily compressed refrigerant through central pressure connection holes of a bearing(161), a low pressure cylinder(121), a central plate(140), and a high pressure cylinder(131). |
