PROBLEM TO BE SOLVED: To provide a two-cylinder rotary compressor capable of reducing a frictional loss between a crankshaft and bearings and suppressing a power consumption. SOLUTION: This two-cylinder rotary compressor 1 comprises two rolling piston type cylinders 17a and 17b driven by a crankshaft 14 formed by shifting two crank webs 19a and 19b by 180°relative to the rotating center thereof. Blades 20a and 20b partitioning the compression chamber of the cylinder into a high pressure side and a low pressure side, cylinder gas suction passages 21a and 21b, and delivery holes are disposed, for each cylinder, at positions shifted by 180°relative to the rotating center of the crankshaft 14. The compression timings of two cylinders 17a and 17b are made to match each other. COPYRIGHT: (C)2004,JPO
