-12- ABSTRACT OF THE DISCLOSURE Automatic, autonomous apparatus for the fast production of polyurethane foam, in which the foam is produced by mixing an isocyanate with a polyalcohol. It comprises a tight storage tank with two compartments, each of which contains one of the aforementioned products, the upper part of the tank being provided with a solid propellant trip or starter, which generates a pressurizat- ion gas for the tank. In the lower part of the storage tank, there is a pressure threshold mixer, whose operation is automatically controlled by the pressure prevailingin the tank and which has a mixing chamber entered (under the effect of the same pressure) by the isocyanate and the polyol via lateral injection nozzles, which produce a rotation of the mixture, the polyols being previously emulsified by a neutral gas (such as air or nitrogen) from a pressurized storage container.
