The invention relates to a cock for filling tanks, comprising a hollow head (1) that supports a valve device (2) associated with a float (3) by means of an intermediate device, also comprising a vertical tube (11) connected to the hollow head (1), in which the vertical tube (11) is housed inside a central passage (13) in the float (3) which moves as the level of water in the tank rises and falls. The float (3) is connected to a bush (12) that is coupled around the vertical tube (11) along which the bush (12) moves, and the upward and downward movement of the float (3) drags the bush (12) when the float (3) is anchored thereto. In this way, the height of the float can be adjusted quickly and effectively according to the fill volume of the tank. |
