ABSTRACT:
The turbo-compressor air supply system of the present invention supplies air to a paint spray system or the like at an elevated pressure. The turbo-compressor includes a housing and a rotatable, vertically-disposed drive shaft centrally disposed within the housing, and a bearing housing which houses a concentrically disposed bearing. The system comprises a rotatable section centrally disposed about the shaft. The section includes a first rotor and a second rotor. Each rotor comprises a first series of blades spirally arrayed about the center of the shaft. The first series of blades are sandwiched between a first pair of plates. The rotors are rotatably driven in the same direction as the shaft, as air is directed onto and through the blades. The rotors are coaxial with the shaft. The rotatable section also includes a tubular sleeve which is mounted about the shaft. The sleeve separates the rotors, and the sleeve is rotatable with the rotors and the shaft in the same direction as the rotors and the shaft. The turbo-compressor also includes a stationary section, which is centrally disposed about the shaft. The stationary section includes a stator, which comprises a series of vanes spirally arrayed around the center of the central passage. The vanes are sandwiched between a pair of stator plates. The stator is coaxial with the shaft. For variations including more than one stator, the stators are each separated by a ring which is mounted between successive stators. The air is fed into the top of the turbo-compressor and exits through the bottom thereof.
