Abstract
Abstract The hydraulic turbine system includes: an electric generator; rotary turbine blades; a hydraulic pump for operation by rotation of the turbine blades; a hydraulic motor for driving the generator; a hydraulic reservoir; and connections between the pump, the motor and the reservoir for causing the motor to operate in response to rotation of the turbine blades by water flow.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
108 words
A hydraulic hydroelectric turbine system comprising: an electric generator; rotary turbine blades; hydraulic pump means for operation by rotation of said turbine blades; hydraulic motor means operatively mechanically coupled to said generator for driving the same and having an inlet and an outlet; a hydraulic fluid reservoir hydraulically coupled to said outlet of said motor means; and connecting means including hydraulic lines connecting said pump means respectively to said inlet of said hydraulic motor means and, to said reservoir in a closed hydraulic loop for operating said motor means by hydraulic fluid pumped by said pump means in response to rotation of said turbine blades by water flow.
Claim 2
Dependent Claim
108 words
A hydraulic hydroelectric turbine system comprising: an electric generator; rotary turbine blades; hydraulic pump means for operation by rotation of said turbine blades; hydraulic motor means operatively mechanically coupled to said generator for driving the same and having an inlet and an outlet; a hydraulic fluid reservoir hydraulically coupled to said outlet of said motor means; and connecting means including hydraulic lines connecting said pump means respectively to said inlet of said hydraulic motor means and, to said reservoir in a closed hydraulic loop for operating said motor means by hydraulic fluid pumped by said pump means in response to rotation of said turbine blades by water flow.
Claim 3
Dependent Claim
64 words
The hydraulic turbine system of claim 1 in which: said pump means is reversible; and said connecting means include a shuttle valve connected between said pump means and the inlet of said hydraulic motor means for automatically operating the latter in either direction of operation of said pump means, and check valves operatively connecting the opposite sides of said pump means to said reservoir.
Claim 4
Dependent Claim
