Abstract
Check valve for gases, essentially consisting of a metal box body provided at its base and side faces of holes for the passage of gases and, in the vicinity of its mouth, an intermediate partition with holes of considerable section, serving as a fastening to a remarkably flexible membrane, retained by its central part and susceptible to be applied against them, eventually determining its sealing, caused by the effect of pressure of the gas entering the valve through the holes of its base and sides, while the circulation in the opposite direction produces the flexion of the end portions of the membrane and the release of the holes through the wall parallel to the base. Whatever the circumstances that concur in the essentiality of the utility model defined in the previous claim, whose purpose is :. (Machine-translation by Google Translate, not legally binding)
