ROTARY SLIDING VANE COMPRESSOR

摘要

The present invention relates to a positive displacement rotary gas, e.g. air, compressor of the eccentric rotor sliding vane type and particularly, but not exclusively, to a compressor wherein the rotor is mounted on an extended shaft of an electric motor. The compressor comprises a cylindrical rotor provided with a plurality of radially extending grooves each defined by a radially extending inner most grove bottom and first and second parallel groove walls extending outwardly therefrom wherein at least the first groove wall is joined to the groove bottom by a first radius portion.
