    摘要： In a rotary compressor of a vane rotary type, an outer peripheral surface of an eccentric portion 41 of a shaft 4 on a side adjacent to a center of the shaft 4 is located radially inwardly of an outer peripheral surface of a main shaft 42 inserted in a main bearing 7 and that of an auxiliary shaft 43 inserted in an auxiliary bearing 8. Also, a back clearance means used in mounting a piston 9 on the shaft 4 is provided in each of an inner peripheral surface of the piston 9 and the eccentric portion 41 of the shaft 4. Such configurations can reduce a diameter of the eccentric portion 41. A reduction in diameter of the eccentric portion 41 can reduce a viscous force of oil acting between the eccentric portion 41 of the shaft 4 and the inner peripheral surface of the piston 9 to thereby reduce a rotational moment about a center of the eccentric portion 41 of the shaft 4, which rotational moment acts on the piston 9 in a direction of rotation of the shaft 4, thus making it possible to reduce a sliding loss that is generated by a reciprocating motion of a vane 11 in a vane groove 10.

    摘要： Disclosed is a vane compressor (1A) in which cylinders (35, 36) concentrically formed at the side of a rotor (3) are eccentrically inserted in ring-shaped spaces (23, 24) between cylindrical parts (21, 22, 12) concentrically formed at the side of a stator (2). A pair of radially extending vane attachment grooves (37) is formed in the rotor (3), and vanes (4) are slidably attached in the vane attachment grooves (37). Compression chambers (51 to 54) the volumes of which repeatedly increase and decrease with each rotation of the rotor (3) are concentrically formed in multiple stages by the cylindrical parts (21, 22, 12) of the stator (2), the cylinders (35, 36) of the rotor (3), and comb-tooth parts (42, 43) of the vanes (4). It is possible to realize a vane compressor in which compression chambers can be concentrically arranged in multiple stages in a simple structure by suppressing increase in the number of components to the minimum level.

    摘要： A scroll compressor disclosed herein is configured such that an arcuate section is formed from a suction end of a wrap to a first point to increase a suction volume and a logarithmic spiral section in which the wrap thickness is increased is formed from a second point to a discharge end of the wrap. This may increase a volume ratio of the compressor so as to increase a capacity of the compressor and prevent damage on the wrap due to a high compression ratio operation, thereby enhancing reliability of the compressor.
