Abstract

PURPOSE: To improve the stability of the water supply pressure and to reduce the installation space by providing an automatic constant-open valve operating when a pressure detector detects the predetermined upper limit or lower limit pressure of a pressure tank and pump delaying means driven by receiving the operation of the valve.
CONSTITUTION: In a case where the quantity of used water supplied through a water supply plug 10 has decreased, the quantity of water supplied within a pressure tank 7 increases by means of a pump 1. When the pressure within the pressure tank 7 reaches the upper limit pressure in accordance with the increase in the stored quantity of water, a detector 8 detects it, and an automatic constant-open valve 6 is opened and the pump 1 is driven in a state where the side of its exhaust pipe 5 is closed. Simultaneously when the pressure detector 8 detects the upper limit pressure, a timer 13 is operated, and after the lapse of a predetermined times interval, the contact point of the timer 13 is opened and a constant-close electromagnetic switch 15 is opened, and the driving of a motor 14 is discontinued to stop the pump 1. In this manner, even when the difference between the upper and lower limit pressures is made small, the water supply pressure is stabilized, and the difference in the capacity can be made small. Therefore, the capacity of the pressure tank 7 can be made small and the intellation space can be also made small.
