Abstract
Improved valve for bird drinkers, of the type comprising a shank located inside the container container, determines a sensor operated by the animal itself, essentially characterized in that the shank passes through the central hole of a flat front bowl which is pressed by a compression spring supported by a thickening of the rod towards a flexible washer retained by a nut fixed to the upper end of the rod, said cup being housed and retained in a slight internal taper of the sprue feeding mouth and coupled to its dye by means of an O-ring, with the particularity that the diameter of the central hole of the bowl is greater than the diameter of the rod, constituting the passage of the liquid when the animal drives the lower end of the rod.
