ABSTRACT:
A radical flow mechanism is provided having a symmetric housing assembly defining a hollow rotor chamber. A symmetric shaft and rotor assembly is supported for rotation in the rotor chamber. A plurality of radial flow paths are defined by the rotor and the housing assembly. The assembled module may be powered by a pressurized motive fluid that flows radially inward to rotate the rotor. Alternatively, the rotor may be driven by an external power source so that a working fluid increases in potential energy as it moves centrifugally outward. The assembled module is symmetric about the rotor member so that the rotor can be orientated for either direction of rotation and so that power takeoff or power connection can be to either side of the module. Also, the module is constructed so that the seals are located at an interface having a low pressure differential and the bearings are located adjacent an area encouraging heat dissipation.
