Abstract:
A rotary compressor having two cylinders includes crankshaft having first eccentric portion and second eccentric portion connected to each other by connecting portion. The rotary compressor further includes two compressive elements that compress working fluid in cylinder as first piston inserted over first eccentric portion eccentrically rotates in accordance with rotation of crankshaft. Further, first piston inserted over first eccentric portion undergoes assembly by being inserted over first eccentric portion through second eccentric portion. Further, a releasing portion is provided at each of outer diameter portions of first eccentric portion and second eccentric portion.
