IMPROVEMENTS IN THE CONSTRUCTION OF PNEUMATIC SOUND WARNINGS, essentially characterized by combining a closed hollow chamber, but which leads, however, to the outside, through the projecting horn of sound warnings, and to which, on the other hand, air is supplied to pressure, with a valve seat that is mounted coaxially with respect to the tube, being arranged in a stationary manner and housed inside the aforementioned hollow chamber, having a diaphragm behind but separate and coaxial with said valve seat. elastic for the subsequent closure of said chamber, in whose elastic diaphragm is mounted, at its center, one of the ends of a piece axially adjustable with respect to the diaphragm in question, so that the other end of the said piece bears the valve itself intended to come into contact and separate from the aforementioned seat, all with the particularity that the aforementioned piece fits able is mounted adaptable and adjustable on the diaphragm to vary the effective length of said piece and thereby achieve the correct adjustment of the position of the said valve with respect to said seat.
