The lower base of the container body incorporates a check valve for the intake of water. The bottom of the third, vertical tube includes a check valve with a vertically movable obturator, extended at the bottom by means of an axial rod. The obturator is connected, by means of a flexible element, to a weight floating on the surface of the water inside. The pump functions continuously with no energy to actuate it other than that of the pressurized air entering its top part.</p> |
