Abstract
There is disclosed a rotary compressor which delays a pressure rise on a high pressure chamber side in a cylinder of a rotary compression element to decrease a high pressure load applied to a roller and a rotary shaft, thereby improving performance. In the rotary compressor including a sealed container in which an electromotive element (a driving element) and first and second rotary compression elements driven by a rotary shaft of the electromotive element are included, each of the rotary compression elements being constituted of a cylinder, a roller fitted into an eccentric portion formed on the rotary shaft to eccentrically rotate in the cylinder, and a vane which abuts on the roller to partition the inside of the cylinder into a low pressure chamber side and a high pressure chamber side, the inner diameter of a suction passage formed in each cylinder is 59% or more and 70% or less of the thickness of the cylinder.
