Integrated fluid dynamoelectric machine

A fluid dynamoelectric machine comprising, a rotor, a circular array of rotatable blades fixed to said rotor, and rotatable therewith, a shroud disposed at the radial outer tip of said rotatable blades, a stator encircling said rotor, a conductive coil disposed in said stator and encircling said rotor, a circular array of stationary blades disposed in said stator, a first brush so disposed to make electrical contact with said rotating shroud, a second brush disposed to make electrical contact with said rotating rotor, whereby in one mode of operation current flows through said shroud, rotatable blades and rotor so that when power is supplied to said brushes fluid is pumped by said machine and in another mode when pressurized fluid is directed through said blades said machine generates power.
