Rotary Compressor

Abstract: This rotary compressor includes: a rotational shaft; a bearing that is configured from a slip bearing and that has an inner diameter surface that supports the rotational shaft; a cylinder chamber including a suction chamber into which a refrigerant is sucked in, and a compression chamber in which the refrigerant is compressed; and a crank part that is attached to the rotational shaft and that rotates eccentrically in the cylinder chamber. A gap to which refrigerating machine oil is supplied is formed between the rotational shaft and the inner diameter surface of the slip bearing. The slip bearing has anisotropy with respect to the oil film rigidity of the refrigerating machine oil. A working angle of a gas load generated by compression of the refrigerant caused by the eccentric rotation of the crank part changes in accordance with a crank angle. When a fluctuation range of the working angle of the gas load is a first angle range, an axial direction of high oil film rigidity, indicating the direction in which the oil film rigidity of the slip bearing is highest, is disposed in the first angle range.
