ABSTRACT:
A rotary compressor includes a cylindrical-shaped housing, a rotor rotatably mounted in the housing and formed with diametrically extending slits, and a pair of movable vanes each slidably disposed in each of the slits with its opposite ends extending beyond the associated slit in abutting relation to the inner surface of the housing. The clearances between the movable vanes and the slits of the rotor are made larger about the central portion of the rotor than adjacent to the outer periphery thereof by making each of the vanes thinner about its central portion than at its opposite end portions or making each of the slits wider about the central portion of the rotor than adjacent to the outer periphery of the rotor. With the arrangement, shearing stresses caused by shearing of oil in the compressor can be suppressed to thereby reduce a loss in the torque of the compressor, and the maximum stress on the movable vanes can be limited below an allowable stress to improve the anti-breakage characteristics of the vanes.
