Abstract

PURPOSE: To supply certainly air in an air tank without leakage to a pressure tank and recover drained water completely, by introducing air into the air tank and, after this, supplying the water of the pressure tank into the air tank.
CONSTITUTION: A water supply tube 23 for pushing out air which is provided with an automatic valve 23 which opens when a pump 1 is being driven is connected between the bottom of an air tank 8 and the pump 1, and a water discharge tube 18 connected to the discharge opening 17e of a jet pump 17 is connected to an induction pump 20 on the side of a water receiving tank 19. By this arrangement, water is supplied to a pressure tank 5, when the pump 1 is driven, and water flows into an air tank 8 through the water supply tube 23 and an automatic valve 23. Accordingly, the air filling in the air tank 8 is always supplied through a tube 10 to the pressure tank 5. When the pump 1 is stopped, the automatic valve 23 is closed and automatic valves 15 and 16 open, enabling recovery of the water in the air tank 8 through the jet pump 17 without draining it into the induction pump 20.
