Summary: | An object of the present invention is to provide a method for manufacturing a multi-stage compression type rotary compressor which can avoid the replacement of parts to be used as much as possible to reduce costs and also which enables easily setting an appropriate displacement volume ratio while preventing the compressor from being increased in size. The gist of the present invention is that an inner diameter of a lower cylinder is altered without altering its thickness (or height), and a displacement volume ratio between first and second rotary compression elements is set to an optimum value in accordance with the alteration. |
