Patent ID: 8100577

Claim:
A fluid blending apparatus comprising: a source of a predetermined fluid which is dispensable into a fluid inlet through which said predetermined fluid flows into a pump assembly; said pump assembly comprising a pump rotating shaft, which is configured as a positive displacement pump, said pump forming a main pump drive for said predetermined fluid; a fluid outlet through which said predetermined fluid exits said pump assembly and enters a main fluid stream; a mixing chamber in which a main fluid flows through from a mixing chamber inlet and initial mixing with said predetermined fluid takes place; a turbine blade assembly wherein blades of said turbine blade assembly are located on a turning wheel positioned in such an angle as to provide a maximum torque with a minimum pressure drop; a turbine shaft in mechanical communication with a turbine drive system and configured so as to transfer an energy of the rotating turbine blade assembly to said turbine drive system, said turbine drive system being in mechanical communication with a pump drive system and configured so as to transfer a rotational energy to said pump drive system of said pump assembly, said pump drive system being in mechanical communication with said pump assembly shaft; and a mixing chamber outlet through which a mixed main fluid and predetermined fluid flows on demand.
