Abstract
PURPOSE: To enable to discharge water and recover the discharged water promptly, by effecting supply of air through combination of an air tank and a jet pump mechanism in an air feeding apparatus for a pressure tank type water supplying apparatus.
CONSTITUTION: When an automatic valve 16 is opened, pressurized water from a pressure tank 5 is ejected from a nozzle 17c via an outlet port 5a, water supply pipe 14, and jet pump 17, i.e., its driving inlet port 17b. Water thus ejected from the nozzle 17c draws water in an air tank 8 from a suction port 17a of the pump 17 and is mixed with the same. While the water passes through a diffuser portion 17d, the velocity of water flow is decreased and its pressure is increased, and then water is discharged from an outlet port 17e. Therefore, water passed through the pump 17 is carried back into a water reservoir tank 19 via the automatic valve 16 and a discharge pipe 18. When water in the air tank 8 is drawn out, a vave 11 is opened and atmospheric air is introduced into the air tank 8. By subsequent closing of the automatic valve 16, pressurized water in the tank 5 flows back toward the suction port 17a and is carried into the air tank 8.
