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 significant volume changes as they move about the cavity during rotation of the rotor, the vanes thus cooperating with the inner stator wall to compress gas entering the inlet passage, such that as it leaves through the discharge passage, it is at a higher pressure. Means provide a film of lubricant on the inner stator wall, with the outer tips of the vanes each possessing a compound contour that interacts with the film of lubricant to effect a good seal with the inner stator wall, while minimizing friction.

A low frictional loss, rotary vane gas compressor utilizing a housing having a generally elliptical cavity therein, and a rotor disposed in said cavity, with the axis of rotation of said rotor being offset from the central axis of said cavity, said housing having an inlet passage and a discharge passage, each in contact with said cavity, said rotor having a plurality of radial slots in equally spaced relation about its periphery, a slidable vane of minimal weight being disposed in each of said slots, with the outer tip of each vane being in close proximity to an inner stator wall that defines the outer boundary of said cavity, said vanes serving to define a plurality of chambers in said cavity, which chambers undergo significant volume changes as they move about said cavity during rotation of said rotor, said vanes thus cooperating with said inner stator wall to compress gas entering said inlet passage, such that the gas thereafter leaving through said discharge passage is at a higher pressure, means for providing a film of lubricant on said inner stator wall, latter means including the use of a plurality of radial passages defined in said rotor, with a metering nozzle located on the outer end of each such radial passage, such that the quantity and dispersion of the lubricant flow therefrom will be controlled in a desired manner, the outer tips of said vanes each possessing a compound contour that interacts with such film of lubricant to effect a good seal with said inner stator wall, while minimizing friction.
