Abstract

Valve for the extraction of dosed quantities of aerosol substances from containers containing them, comprising an internal elongate body fixed to a saucer-shaped element, applicable in turn to a container of aerosol substance, an external body mounted on the body interior and a stem, a portion of which is housed inside a chamber, formed in the inner body, while, another portion protrudes from the said chamber being the latter obtained in the part of an extremity of the inner body and presenting a embouchure closed by a sealed garrison pierced by the aforementioned stem, coming the same bounded by a side wall and a bottom wall, in each of which is practiced at least a small step, in addition to which is provided, on the wall in the background, an opening of dimensions greater than those of the small indicated steps, coinciding with which, towards the outside of the in this case, an elongated tubular wall extends on the outer surface of which an annular groove is formed, while on the inner surface thereof a protruding shoulder is provided and at least one groove of limited length is provided., one end of which opens in said chamber, while the other end opens in an intermediate zone of the tubular wall, the said outer body substantially presenting the shape of a vessel, with its free edge elastically deformable and superposed to pressure to the side wall delimiting the said chamber, closing the small step practiced therein, presented the outer body in the form of a bottom provided with an opening in which the said tubular wall of the inner body is inserted, coinciding with the throat of which is located and solidly retained in sealed form the said bottom, being practiced in the aforementioned pa said recess protruding from the said chamber, an axial passage in communication with the outside through its free end and through a small inclined passage in relation to the axial passage made in the thickness of said shank, close to the end of the leg. As it is located inside the chamber, a small lining is mounted and a ring is provided on which rests one of the ends of a spring whose opposite end rests on said shoulder of said tubular wall, in the rest position of the valve, said small inclined step of the stem being located outside of. Said chamber, beyond the garrison, which closes its embouchure, the said small joint belonging to the stem displaced towards the repeated chamber being in relation to the end of said inner groove of said tubular wall, said rod being movable, overcoming the action of the expressed spring, towards an operative position in which said small inclined passage opens inside the repeated chamber, while the said small one. The integral lining of the rod is placed in contact with a smooth surface area of said tubular wall with which it performs sealing. (Machine-translation by Google Translate, not legally binding)
