ABSTRACT:
A fluid driven turbine for use in generating power by driving a load (32) with a fluid stream intercepting blades (12) of the turbine and the turbine applying power to the load during rotation of the blades in accordance with the invention includes a variable displacement hydraulic pump (19) which is driven by rotation of the blades, including a displacement control (57) having an element (62) which is responsive to a control signal for varying the displacement of the variable displacement hydraulic pump for producing a pressurized hydraulic fluid output to drive the load; and a hydraulic control valve (90) which generates the control signal in response to a hydraulic signal which is a function of speed changes of the blades and a pressure dropping orifice (114"), responsive to the hydraulic signal which is a function of speed changes of the blades which bleeds the hydraulic signal to a lower pressure, the orifice producing a coefficient of discharge of liquid independent of viscosity thereof; and wherein the control signal causes the element to vary displacement of the variable displacement pump which is a function of speed changes of the blades.
