Abstract

PURPOSE: To permit a pressure tank to be effectively utilized by controlling the inlet and outlet of the pressure tank with the operation of a pressure switch to enclose a large amount of air in the pressure tank.
CONSTITUTION: While water in a pressure tank 13, when consumed in plenty, is lowered lower than the lower limit L1 of level to make air 35 flow out through a connection pipe 11, the internal pressure is lowered lower than that P1 in the lower limit L1 of level to close a flow path 21 communicating to a driving channel 21 by a diaphragm 27 of the pressure switch 15. Thus the internal pressure in the pressure tank 13 is maintained lower than that the internal pressure P1 in the lower limit L1 of level to prevent the effluence of air 35. That is, a great amount of air 35 can be enclosed in the pressure tank 13 which can be effectively utilized by setting the lower limit L1 of level to such a position as air does not flow out through the connection pipe 11.
