<p>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.</p> |
