Abstract
The present invention is for the efficient transfer of mechanical power through a fluid medium. The various embodiments of the present invention exploit the natural physical properties of fluids to create a more efficient means of driving fluids as well as transferring power from propelled fluids. The present invention employs an impeller assembly in a variety of applications including hydroelectric turbines, fluid turbines, turbine transmissions and pumps of various types. The multi-disk impeller assembly having a central cavity, a specialized central hub design and reinforcing backing plates contribute to greater efficiency and less turbulence, friction and noise.
