VANE COMPRESSOR

摘要

Disclosed is a vane compressor that has a plurality of vanes, performing compression such that the normals of arcs formed by the tips of the vanes are always in near perfect alignment with normals from the inside surface of a cylinder. In order to produce said alignment, each vane is always held in the normal direction of the inside surface of the cylinder or in a direction at a constant angle thereto, and the vanes are supported inside a rotor section so as to be able to rotate and move with respect to said rotor section. A recess or ring-shaped groove, concentric with the inside surface of the cylinder, is formed in a cylinder head and a cylinder-side edge surface of a frame. A pair of vane aligners, each of which has a tabular protrusion or a groove on or in a partial-ring-shaped edge surface, are inserted into the aforementioned recess or groove, and said tabular protrusions or grooves are fitted in or around grooves or protrusions provided in or on the vanes.
