Abstract

Pressure reducing valve and automatic liquid dosing, characterized essentially by having the appropriate configuration of a container or chamber, preferably cylindrical, from which depart suitable tubular branches comprising at least one link for fluid lines, another conduit for communicating to the valve body with a reservoir containing liquid at ambient pressure, or at higher pressure, and another analogous conduit which may be placed parallel to the geometrical axis of said container and which, through suitable elbows, is joined to the lower point of a hollow spherical foot that communicates with that same receiver through a short tubular section, defining at the end of this latter connecting tube a frustoconical neck that penetrates the aforementioned spherical foot and that is aligned axially with one end in the manner of shutter of coincident shape attached to a shaft that starts from the lower center point of a float that is housed inside the aforementioned container and that remains constantly in a suitable position thanks to the guide offered by suitable lugs or rings provided in the interior paramente of the repeated container.
