Abstract

PURPOSE: To prevent automatically a fluid in vacuum tank from flowing out by a method wherein a peep window for a vacuum tank is provided in double structure to allow a fluid of constant pressure therein, and a breakage of the peep window is detected by change in pressure to actuate a damper mechanism.
CONSTITUTION: A peep window 18 through which to check for internal condition of a vacuum tank 14 through to a shaft seal is provided in double structure with transparent plate glasses 19, 20, and gas or liquid of constant pressure is allowed to exist between the plate glasses 19 and 20. A pressure between the plate glasses is detected on a pressure detecting device 21, and an arrangement is such that where the peep window 18 is damaged and the pressure changes accordingly, a damper 22 is actuated automatically to prevent the fluid in the vacuum tank from flowing out. A sealing fluid feeder of high reliability is thus obtainable.
