PURPOSE:In a pressure container where a bag body is provided in a tank formed with hollow rigid member, to circulate liquid contained in the bag body continuously by providing more than one openings conducting with the bag body while having different direction from the lower opening thereby flowing in liquid from another opening while flowing out through lower opening. CONSTITUTION:A bag body 2 made of soft material is provided in a tank 1 while air is encapsulated in an air-tight space 3 to be formed with the inner wall of the tank 1 to produce a pressure container, where upper and lower openings 4, 7 are made in the bag body 2. Water fed by a pump 17 will flow through a liquid feed/discharge pipe 9, check valves 8, 81 and the upper opening 4 into the bag body 2. Consequently the bag body 2 will expand to compress air in said space 3 thereby the pressure will reach to the upper limit to function a pressure switch 19 and to stop the pump 17. Thereafter water in the bag body 2 is fed through the lower opening 7. |
