Figure 1 is a sectional view showing the position of the load adjustment valve, the feed water inflow route, and the thickness of the reflux layer at maximum load, and Figure 2 is a sectional view showing the position of the load adjustment valve, the water supply inflow route, and the thickness of the reflux layer at minimum load. A cross-sectional view showing a thin state,
FIG. 3 shows a motor M that controls the drive of the load adjustment valve 20.
1 and a block diagram of the control circuit of the motor M2 that adjusts the valve opening of the electric water supply valve so as to be proportionally linked to the position of the load regulating valve. Figure 5 shows the characteristics of the valve opening with respect to the load when an electric water supply valve whose valve opening is controlled is installed, and Figure 5 shows the characteristics of the valve opening with respect to the load when an ON-OFF valve is installed on the water supply valve. The figure is a water braking dynamometer performance curve chart using a square scale, and FIG. 7 is a water braking dynamometer performance chart using a double-logarithmic scale. 3...

装置。 A casing main body 3 rotatably supports a rotating main shaft 4, a runner 5 having radial blades on both sides and rotated by the rotating main shaft 4 within the casing main body 3, and a suitable runner Stators 6a and 6b fixed in the casing body 3 facing each other with a space therebetween and having radially formed blades, a water supply pipe 10 communicating between the stators 6a and 6b and the runner 5, and the stator 6a, 6b and a load adjustment valve 20 connected to a drive device to move within the recirculation water layer 8 between the runners 5 in a direction toward and away from the center of the recirculation. The pipe 10 is characterized by being provided with an electric water supply valve 22 that is linked to the position of the load adjustment valve 20 and whose valve opening is electrically controlled in proportion to a change in the position of the load adjustment valve 20. Control device.
