ABSTRACT:
An improved vane compressor is provided which employs a rotor comprising: a hollow boss element into which a rotary shaft is force fitted; at least two pairs of lateral plates formed upright on a peripheral surface of said boss element; and a peripheral element fitted between opposed ones of the lateral plates of adjacent pairs; wherein said boss element and said lateral plates are made of a metal having a sufficient mechanical strength, and said peripheral element is made of a material which has a smaller specific gravity than that of said metal and has a coefficient of friction small enough to keep sliding contact faces of parts facing said rotor in the pump section of the compressor from undergoing substantial abrasion.
