Abstract

PURPOSE: To aim at preventing any trouble from occurring by making a governing valve controllable with discharge pressure oil of an auxiliary oil pump at a time when pressure in this discharge pressure oil is less than the specified value, in case of a device which opens or closes the governing valve with the discharge pressure oil of a main oil pump being driven by a turbine.
CONSTITUTION: In case of a device which controls a governing valve 4 for is opening or closing by discharge presses oil out of the main oil pump 7 directly connected to a steam turbine 6, there is provided with a steam-driven auxiliary oil pump 13. Steam branched off from the downstream side of a stop valve 2 being opened by turbine starting is fed to this auxiliary oil pump 13 via a steam stop valve 12, and the auxiliary oil pump 13 is driven by this steam, inhaling oil in an oil tank and discharging it out, then the actuator 5 is made so as to be introduced via a pressure control valve 14. And, the steam stop valve 12 is controlled so as to be opened when detected pressure is less than the specified one according to output of a detector 10 which detects pressure in the discharge pressure oil in the main oil pump 7.
