Abstract
PURPOSE: To achieve constant and accurate guide vane closing when closing guide vane by activating oil hydraulic pressure in guide vane closing direction at the opening below the appropriate guide vane opening in the pressure chamber which acts in guide vane closing direction and is provided on the servo motor.
CONSTITUTION: At a guide vane switching device of a hydraulic device, a guide vane operating link 1 is activated in the closing direction by a weight 2 hung from a projection 3. A servo motor 4 is also connected with the projection 3, and the guide vane 1 is opened by conducting pressurized oil into a port 5 below the projection 3 from a pressurized oil source which is constituted of a pump 8 and a pressurized oil tank 9 through a pressure distributing valve 7. The pressure distributing valve 7 is controlled by the direction from a governer 12 and the opening of the guide vane 1 through a link mechanism 13W17. In this case, an operation valve 2, which is connected to a port 24 of the servo motor 4, being controlled by a switch 23 which is closed at the appropriate valve opening, is connected with an accumulator 24.
