Abstract

PURPOSE: To enable the decrease in the capacity of a pressure tank and the narrowing of the installation space by providing delay means in a pump driving prime mover and driving the pump in a predetermined period of time after detecting a predetermined pressure of the pressure tank.
CONSTITUTION: When the pressure within a pressure tank 7 reaches an upper limit pressure, a pressure detector 8 detects it, a pump 1 is driven in a state where the side of an exhaust pipe 5 of the pump 1 is completely closed. Similtaneously when the pressure detector 8 detects the upper limit pressure, the timer 13 starts its operation to open the contact of the timer 13 and open a constant-close electromagnetic switching value 15, and also to stop the motor and the pump 1, after the lapse of a preset time. Therefore, even when the difference between the upper limit pressure and the lower limit pressure is made small, the difference in the capacity can be made small, and hence the pressure tank 7 can be made into a small capacity, and the installation space can be made small.
