Patent ID: 7810322

Claim:
A transmission apparatus configured to transmit energy from a power source to work unite the transmission apparatus comprising: an outer housing defining an interior region containing a fluid; an input shaft being coupled to a power source to receive energy there from; said input shaft being couple to a pump to transfer energy from said power source into the fluid and then to a multi-stage turbine; a first turbine positioned in front of said pump and is fixed to an output shaft; at least a second turbine located in series after said first turbine rotationally secured to said output shaft with a one-way overrunning clutch or multiple-disc clutch; a plurality of valves located after each turbine that are opened to discharge fluid or gas after each turbine or closed to allow flow to said second or subsequent turbine(s) wherein; said one-way overrunning clutch or said multiple-disc clutch will be locked in the same direction of said first turbine and will be free to rotate in an opposing direction without appreciable drag on said output shaft, and said turbines will transfer power when the differential pressure before and after said turbines is sufficient to turn said turbines and lock said one-way overrunning clutch or multi-disc clutch and to transfer power to said output shaft.
