ABSTRACT:
A rotary vane compressor has a compressor housing which contains an oval chamber. A cylindrical rotor is mounted on an axial shaft and has radial vanes which engage the chamber and slide radially inward and outward in slots formed in the rotor as the shaft rotates. A pair of thrust shoulders are on the shaft, spaced axially apart from each other exterior of the rotor and facing in axially opposite directions. A deep groove ball bearing assembly is stationarily mounted in the housing in engagement with both of the shoulders on the shaft. Radial, moment, and thrust in both axial directions applied to the shaft are transferred by the shoulders through the bearing assembly to the compressor housing.
