Abstract
PURPOSE:To prevent reduction of air in a pressure tank by feeding pulsated water from the compressing side to the suction side of a pump during pumping to supply additional air successively. CONSTITUTION:While a diaphragm 25 is sucked more, a piston 63 pushes a movable valve body 61 in the same direction as the diaphragm to the point where a pilot orifice 57 is closed. The diaphragm 57 is restored by the forces of compressed water and reaction of a push spring 49. Air fed in an air space 45 during the suction action of the diaphragm 25 is squeezed by the restoration of the diaphragm to run through a duct 43 and an orifice 41 and pushes a ball 39 into a pressure tank 49. Successive supply of air during pumping may prevent reduction of air in the pressure tank 9.
