<p>A rotor is provided wherein a rotor core (10) and a jacket (11) cooperate to provide a continuous variation of area for fluid transit. This continuous variation of area for fluid transit produces a continuous axial acceleration of fluid and provides a first pressure gradient. The invention also provides simultaneously for blades (12) having a continuously varying angle provided in the area for fluid transit, and causes a second pressure gradient. The varying of the fluid transit area and the angle of the blades (12) are designed to have the first and second pressure gradients be complimentary, and maintain the pressure of the fluid substantially constant. Such continuous varying angle of inclination of the blades provides a continuous angular acceleration of the fluid and corresponding torque. The blades of continuously varying angle of inclination rotate together with the rotor core producing torque.</p> |
