refinement the valves controlled by the lag leggiante

摘要

the subject of the present invention is a valve with two or three ways in which the body is held is formed of a body acts in perpendicular to the flow of fluid.the movement of which is controlled by an auction length appropriate supplies on the end of a float and connected with a middle rigid length appropriate with respect to the height of the reservedi, in which it is immersed, to a body, preferably hollow, which will partially the same liquid contained in the tank receives.when the tank is full, a hydrostatic pressure capable of canceling his weight.when the tank in which it is immersed is empty the weight pulls down the shaft connected with the body to close the access route of water through the valve and raisein this way, the valve opening.
