摘要： PURPOSE:To suppress hunting of pressure in a sealing oil supply device by a method wherein there is provided a dampener for a filler pipe on the high tension side of a differential pressure regulating valve arranged between a sealing part of a shaft and a sealed oil pump. CONSTITUTION:To a filler pipe 11 on the high tension side of a differential pressure regulating valve 6 arranged between a sealed part 3 of a shaft and a sealing oil pump 4 is fixed a dampener 13 provided detachably with a taper pin 17 of an adjust screw 18 having the taper pin 17 in a pressure transmitting hole 16. Therefore, when the pressure in the outlet of the sealing oil pump 4 changes, this pressure change is damped by a dampener 16 and a differential pressure valve 6 does not pulsate. Accordingly, the hunting of pressure of the sealing oil supply device can be suppressed rapidly.

摘要： PURPOSE:To improve response-ability in case of emergency braking, by using a braking device for common use and an emergency braking device. CONSTITUTION:A braking device 5 for common use and an emergency braking device 6 are connected to brake shoes 3. Thus, if operating an emergency handle 35 to the emergency braking side when emergency braking, an emergency change- over valve 24, an emergancy magnet valve 37 and a magnet valve 7 for main braking are de-magnetized, a piston 6b of the emergency braking device 6 falls, the brake shoes 3 are pushed to a brake durm 1 through a link 4 while pressure fluid from a tank 8 with little capacity is immediately fed into a cylinder 5c of the braking device 5 for fommon use, a piston 5b is repidly raised and the pushing of the brake shoes 3 to the brake durm 1 is accelerated.

摘要： PURPOSE:To shorten the rise time of hydraulic pressure when an emergency pump operates by means of a check valve provided to prevent a reverse flow with a passage from the normal pump to the emergency pump though a communicating tube connecting between the discharge side of the normal pump and the suction side of the emergency pump. CONSTITUTION:The normal pump 7 is provided in a main circit 6 extending from an oil tank to a shaft sealing device 3 while an emergency circuit 12 is provided parallel to the main circuit 6 and the emergency pump 1 is provided therein. The discharge side of the normal pump 7 is connected to the suction side of the emergency pump B with a communicating tube 17 having a throttle devie 18 and a check valve 19 is provided in the course to prevent a reverse flow from the emergency pump 13. A check valve 20 is provided in the emergency circuit 12 between the oil tank 20 and the emergency pump 13. This shortens the rise time of hydraulic pressure when the pump 13 is actuated at an emergency as it is always in oil.

摘要： PURPOSE:To eliminate maintenance by automatically discharging drain separated by a vacuum pump by one-time opening of a stop valve at the time of start-up and stoppage of pump and also by the automatic supply of a necessary amount of oil in a drain separator. CONSTITUTION:Until the vacuum pump 21 is operated to a certain vacuum degree and the oil level of the separator tank 27 becomes constant to increase the amount of drain, the stop valve 35 above the conduit 34 is closed, and also when the vacuum degree has reached a constant value and a vacuum switch, not illustrated, provided to an oil tank, for example, is operated, the stop valve 35 is opened to automatically discharge the drain inside the drain chamber 30 to the outside through the conduit 34, the small drain tank 33, and the large drain discharge tank 37. On the other hand, the level switch 40 provided to the separator tank 27 operates the oil automatic supply valve 41 when the oil level 28a is lowered in order to keep the oil level 28a at a standard level at all times for the automatic supply of oil.

摘要： 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.
