Abstract: A hydraulic turbine power generator mounted on a single shaft wherein the hydraulic turbine means includes a plurality of reaction type turbine stages arranged to be in combination, rotatably responsive to the hydraulic fluid coupled to the turbines. One of the turbine stages having axial turbine runner means mounted to the single shaft and having a plurality of adjustable blades for permitting the pitch of the blades to be adjusted for controlling the effective operative fluid head to cause the shaft to rotate at a preselected speed and including means for adjusting the pitch of the adjustable blades. The turbine stages can be a Francis type turbine and a Kaplan type turbine. The hydraulic turbine power generator can be oriented in an upward direction to cause the fluid flow to travel upwardly through the turbine stages and function as a two phase turbine expander resulting in the separation of the liquid phase from the gas/vapor stage.
