<p>PROBLEM TO BE SOLVED: To provide a rotary compressor capable of enlarging an operation range in a low speed operation zone, suppressing degradation of efficiency in a high speed operation zone, and reducing costs.SOLUTION: A rotary compressor includes: a cylinder 50 formed with an intake passage 51 and a discharge hole 53; and a piston 31 having a cylindrical portion 80 and a blade portion 90 which are revolved by rotation of a shaft 22. The cylinder 50 is provided with a bypass passage 55 extended from a position of a rotation angle 90° or more with respect to a prescribed position of the blade portion 90 as a rotation starting point to a position overlapped to the intake passage in an axial view, on an inner peripheral face of the cylinder 50. The bypass passage 55 is formed to choke at a prescribed rotational frequency or more.</p> |
