Rotary 2 stage compressor
2005
Object of the present invention is to provide a fluid loss in the pipe is reduced and the compressor stage 2 is easy to manufacture. The two-stage rotary compressor having a high pressure and low pressure compressed by the compression elements in a sealed container elements, and the intermediate space is connected to the low-pressure compression chamber of the compression elements in a sealed container, a substantially circular shape at least 3 the through hole includes a low-pressure suction pipe in communication with the low pressure compression requirements through the through hole, an intermediate and in communication with the intermediate space through the through-hole discharge tube, the high-pressure suction pipe in communication with the high pressure compression requirements through the through hole , longitudinally along the rotational axis of the column-shaped through hole.
