Abstract

Head of packaging and control of fluids, on receiving containers with self-closing valve, which is designed to allow the controlled passage of gaseous fluids, in liquid phase, from a source of supply to a container container equipped with a valve with self-closing means, characterized essentially by constituting from three fundamental parts coupled together and serving as means of assembly and guidance for a displaceable axial plunger through which the passage of fluid occurs; the first of said parts having a radial hole in communication with the source of supply of the fluid, whose orifice opens into a chamber defined in said piece, which at its lower end widens like an inverted cup on which they are coupled the other two pieces, the outer one of which is constituted in fixing means for a complementary piece of coupling of the assembly to the container that is to be filled, while the third piece is constituted in guide means in the displacement of the plunger, counting this with a flange or annular protrusion that is positioned inside a cylindrical chamber defined in said third piece, a chamber that is in communication with an external source of air under pressure through a radial hole provided in said piece, which counts also with other side holes that communicate with the atmosphere, as well as with a throat in which a spring is positioned recovery that presses against the flange of the plunger, tending to move it upwards.
