Abstract

PURPOSE: To provide the tilted device which is simpler in construction and higher in reliability by a method wherein a single governor is used in common for a plurality of stages, while a main distributing valve is provided for each stage.
CONSTITUTION: The first-stage runner 1 and the second-stage runner 21 are provided on a common shaft 5, and guide vanves 2, 22 are provided for each of the stages. The guide vanes 2, 22 are connected to the main distributing valves 9, 29 through main servomotors 6, 26 respectively, and the valves 9, 29 are operated by a common driving wire 16. For instance, when the spoeed of the turbine is raised, a frequency detector 12 detects this condition and feeds a pulling-down signal to an amplifier 13, an actuator 14 and an auxiliary servomotor 15, whereby the wire 16 is pulled downward. By this operation, the valves 9, 29 are operated, pressure oil is flowed through closing-side throttle valves 8, 28 and into the closing side of the main servomotors 6, 26 so as to close the guide vanes 2, 22, whereby the speed of the turbine is reduced and is governed in such a manner as to maintain the frequency at the value set by a reference frequency setter 11. The opposite side is also governed in a similar manner. The valves 9, 29, the servomotors 6, 26 and return wires 10, 30 used for each of the stages can be adjusted to have the same characteristics.
