Low frictional loss rotary vane gas compressor having superior lubrication characteristics

Abstract From the Canadian patent

A low frictional loss, rotary vane gas compressor utilizing a housing having a generally elliptical cavity therein, and a rotor disposed in the cavity with the axis of, rotation of the rotor being offset from the central axis of the cavity. The housing has an inlet passage and a discharge passage, each in contact with the cavity with the rotor having, a plurality of radial slots in equally spaced relation about its periphery. A slidable vane is disposed in each of these slots with the outer tip of each vane being in close proximity to an inner stator wall that defines the outer boundary of the cavity. The vanes serve to define a plurality of chambers in the cavity which chambers undergo …
