PURPOSE:To certainly achieve regulation for quantity of lubricant supplied to a contained by driving an ejector vacuum pump, stopping the operation of said pump after reducing the pressure to vacuum inside and lubricant tank and a closed container connected to it and subsequently applying the atmo spheric pressure to the tank. CONSTITUTION:The oil or liquid to be charged in a closed container 7 connected through a hose 5 to a lubricant tank 1 is previously charged in the lubricant tank1 and the lubricant tank1 and closed container 7 are evacuated by an ejector vacuum pump 3 provided on the lubricant tank 1. Thereby, the air within the closed container 7 is certainly exhausted. Subsequently, when the pump 3 is suspended, the atmosphere is introduced into the lubricant tank 1 and the tank1 is pressurized with the atmosphere. Therefore, the lubrication can be quickly achieved for the closed container 7 by utilizing the atmospheric pressure. Furthermore, because the regulation of the pressure reduction can be effected by the pump 3, the regulation of the lubricant quantity to the container 1 can be certainly and easily achieved. |
