【発明の詳細な説明】 （産業上の利用分野） 本発明は、内燃機関の潤滑油または他の油圧機器の作動
油を制御用の作動油に兼用した油圧ガバナ装置に係り、
特に、作動油漏れのために生ずるハンチングを防止した
油圧ガバナ装置に関する。Description: TECHNICAL FIELD The present invention relates to a hydraulic governor device in which lubricating oil for an internal combustion engine or hydraulic fluid for other hydraulic equipment is also used as control hydraulic fluid,
In particular, the present invention relates to a hydraulic governor device that prevents hunting caused by hydraulic oil leakage.
（従来の技術） 従来、発電機駆動用ガスタービンの油圧ガバナ装置で

ルポンプで圧送し、パイロットバルブを切換えてパワー
ピストンに送り、出力レバーを作動させて燃料を増減
し、出力を調節している。(Prior Art) Conventionally, in a hydraulic governor device for a gas turbine for driving a generator, hydraulic oil for the device is branched and used from the middle of a bearing lubricating oil pipe (see Japanese Utility Model Laid-Open No. 61-37437).
That is, the lubricating oil supplied from the bearing lubricating oil pipe is pressure-fed by the oil pump, the pilot valve is switched to be fed to the power piston, and the output lever is operated to increase or decrease the fuel to adjust the output.
また、前記と別に油圧ガバナ装置専用に別置タンクを設

る欠点がある。(Problems to be solved by the invention) However, in the former method in which the hydraulic oil of the hydraulic governor device is branched and used from the middle of the bearing lubricating oil pipe, the drain discharge passage and the piston slide are provided between the oil pump and the power piston. There are many places where oil easily leaks such as moving parts or needle valves. Therefore, when the gas turbine engine is stopped for a long time, the hydraulic oil filling the hydraulic governor device leaks from the above-mentioned location and the lubricating oil system becomes empty.
As a result, when the gas turbine engine is used directly connected to the emergency generator, it takes time for the hydraulic oil to fill the hydraulic governor device at the time of startup, and the air accumulated in the hydraulic governor device is compressed during that time. It causes hunting, operates in the direction of increasing fuel, and rotates at 108 ~.
The engine is automatically stopped because it reaches 109% and becomes dangerous. For this reason, emergency generators are usually 30 ~
Although the gas turbine engine must be started within 40 seconds, the gas turbine engine does not start up within that time, resulting in a start failure.
また、後者の油圧ガバナ装置に専用の別置タンクを設置

がある。Also, in the latter method of installing a dedicated separate tank in the hydraulic governor device, it is always necessary to check the oil amount in the separate tank, and when the separate tank is installed below the governor, It is necessary to prevent the oil from returning to the separate tank, and if the separate tank is installed at a position lower than that of the governor, the governor cannot absorb the oil.
