Maximum security hydropneumatic float for tanks based on the fact that its closure arises on the inside in the direction of the pressure by opening and closing the water passage by means of some disks housed between one another that are crossed by the axle (29) and it moves them along the guides (1) when they open and close, with it being characterised by the fact that said disks cut off from lesser to greater the water passage by only using the force of the first time through the dead spaces on the axle run (27) and (28) which allows the ballcock and its lever to be eliminated and to be able to build it completely out of plastic, a hub (45) supplies itself with water, when the water in the tank (68) drops, the hub falls thereby opening the disks and when the level drops it reaches the air chamber (57) lifting the hub until releasing the disks which then return to their seatings thereby ensuring the closure. <IMAGE> |
