| 摘要 | PURPOSE:To accurately replenish a minute amount, by constantly hold pressure in a replenishing tank, a supply tank and a receiving tank and directly connecting the replenishing tank and the supply tank by a pipe while connecting the supply tank and the receiving tank by a siphon. CONSTITUTION:A replenishing tank 1, a supply tank 2 and a receiving tank 3 are successively arranged from above to below and hermetically closed and held to the same pressure by communication pipe 4. The replenishing tank 1 and the supply tank 2 are connected in an air-tight state so as to be made slidable by an up-and-down control mechanism 5 in order to regulate a replenishing amount and the outlet 1-1 of the tank 1 is contacted with the liquid level L of the tank 2 to keep the liquid level L constant. The tanks 2, 3 are communicated by a siphon pipe 6 and a guide body 7 such as sponge or fiber is sealed therein to guide the liquid of the tank 2 to the tank 3 by a capillary phenomenon to replenish the liquid corresponding to the reduced liquid amount in the tank 3. By this method, the replenishment of a minute amount over a long time is accurately and powerlessly performed. | ||||||
