Abstract:
A cyclonic ejection pump comprising:a stator defining an inlet nozzle and an outlet; a rotor having a plurality of blades; a radial injector disposed for injecting a flow of working fluid toward the blades for causing a rotation of the rotor; and at least one exhaust diffusion pressure cone adapted to direct the flow of working fluid from a region of the blades toward the inlet nozzle, the at least one cone defining a longitudinal center line and being positioned in such a way as to define a predetermined angle between its longitudinal center line and a radius of the rotor intersecting the longitudinal center line so as to generate a cyclonic flow within the inlet nozzle for maintaining both a rotation of the rotor and a flow of pumped fluid from the inlet nozzle toward the outlet even where the flow of working fluid toward the blades is directed perpendicularly to a longitudinal axis of the rotor.
