Abstract
A rotary compressor, which contains a motor unit and compression mechanism in a sealed case, transmits the rotational power of the motor to the compression mechanism through a rotary shaft and crankshafts eccentrically provided in the rotary shaft, and compresses a refrigerant in the compression mechanism, wherein the rotary compressor is configured to have H/(φDa•E)=K, and K≦0.065, and the formula 0.35+0.07•K•H≦L/φDb≦0.45+0.07•K•H, assuming that the inside diameter of the cylinder forming the compression mechanism is φDa [mm], the cylinder height is H [mm], the crankshaft eccentricity is E [mm], the crankshaft diameter is φDb [mm], and the sliding lengths of the crankshaft and a roller fitted over the crank are set to L [mm].
