Abstract
Abstract A hydraulic (water) turbine for the generation of electrical power has a single vertical shaft upon which are mounted the turbine rotor, the flywheel, the generator rotor, the oil pump, and the power-output or turbine-speed controller. The system is free from clutches and transmissions which have hitherto been required to drive units associated with the turbine.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
134 words
A water turbine-generator set for the generation of electrical power, comprising: a vertical rigid shaft; a water turbine disposed at the lower end of said shaft and having a turbine rotor connected thereto; a flywheel connected directly to said shaft above said rotor; an electric current generator surrounding said shaft and connected thereto above said flywheel, said generator having a generator rotor; an oil pump connected directly to said shaft for supplying oil under pressure to regulate the output of said set; and a speed control for said turbine connected directly to said shaft, said oil pump being disposed on said shaft above said generator, an intake scroll surrounding said water turbine; and a plurality of support feet mounted on a foundation and supporting said shaft, said turbine and the rotor of said generator.
Claim 2
Dependent Claim
134 words
A water turbine-generator set for the generation of electrical power, comprising: a vertical rigid shaft; a water turbine disposed at the lower end of said shaft and having a turbine rotor connected thereto; a flywheel connected directly to said shaft above said rotor; an electric current generator surrounding said shaft and connected thereto above said flywheel, said generator having a generator rotor; an oil pump connected directly to said shaft for supplying oil under pressure to regulate the output of said set; and a speed control for said turbine connected directly to said shaft, said oil pump being disposed on said shaft above said generator, an intake scroll surrounding said water turbine; and a plurality of support feet mounted on a foundation and supporting said shaft, said turbine and the rotor of said generator.
Claim 3
Dependent Claim
26 words
The water turbine-generator set defined in claim 1, further comprising an oil reservoir for said oil pump disposed on said generator at an upper end thereof.
Claim 4
Dependent Claim
15 words
The water turbine-generator set defined in claim 2 wherein said reservoir surrounds said oil pump.
Claim 5
Dependent Claim
20 words
The water turbine-generator set defined in claim 3 wherein said control is disposed on said shaft above said oil pump.
Claim 6
Dependent Claim
18 words
