Abstract

Metering valve for aerosol, by means of which the extraction of dosed quantities of aerosol substances from containers of such substances is achieved, comprising an internal elongate body fixed to a bushing which in turn is applied to the container, a stem a portion of which protrudes to the outside by an extremity of the inner body, a second portion of which is housed in an inner chamber made in the inner body, and a third portion of which is housed in another inner chamber made in the inner body, inferiorly to the chamber that it houses the above-mentioned second portion of the stem, the upper internal chamber having a mouth closed by a lining pierced by the portion of the stem projecting from the inner body and being delimited by a side wall in which at least one hole is made. It goes through the side wall and is kept closed by an outer body. The inner elongated body is provided with a lower lining housed in the upper internal chamber and supported on the bottom wall that delimits the lower upper inner chamber, as well as a ring mounted superiorly to the lower lining, a spring housed in the upper internal chamber practiced in the internal body, which is supported by its lower extremity on the ring mounted on top of the lower lining and by its upper end on a portion of the shank of larger dimensions both to the upper immediate portion of the latter protruding from the inner body, as to the immediate lower one that is housed in the upper internal chamber made in the inner body, finally providing a tubular element applied to a lower appendix of the internal elongate body.
