PURPOSE:To continuously feed a fixed amount of pressurized liquid from a storage tank, by boosting a pressurized tank to a level almost equal to a pressure of the pressurized liquid and discharging a fixed flow of gas in the tank while maintaining the pressure. CONSTITUTION:If pressure in a tank reaches a preset pressure P4, an opening and closing valve V3a is closed by a detection output from a pressure detector 4a. Then with the lapse of preliminary time, opening and closing valves V1a, V4a are opened, and inactive gas in a pressurized tank 2a is extractively fed out in a fixed flow while maintaining the pressure in the tank by a fixed pressure fixed flow adjusting valve CV2. In accordance with the above, liquid being pressurized to a level almost equal to the preset pressure P4 in a liquid storage tank 1 is fed into the pressurized tank 2a in a fixed flow quantity. |
