ABSTRACT:
A hydroelectric power generator equipment includes a hydraulic turbine which has a runner with blades adjustable of opening thereof and a hollow turbine shaft mounting thereon the runner, a power generator having a hollow shaft connected to the turbine shaft, a hydraulic cylinder mounted on the runner to drive the blades, and first and second liquid passages each passing through the turbine and generator shafts and feeding oil to the hydraulic cylinder to adjust the opening of the runner blades. One of members defining the first and second liquid passages is screwed in the inner wall of the shafts around an axially middle portion of the first and second liquid passages to suppress radial movement of the passage defining member. Some of the members are slidably or firmly inserted in other members so that disassembly is easy.
