Radiator cap consisting essentially of a base part, formed as a bowl with elements suitable for holding, which takes axially attached, by its concave face, a rod in which are coupled a disk with concentric corrugations and a cap of stepped profile, separated both by a spiral spring, arranged around the stem, whose ends sit on the faces facing them, leaving the disk at a convenient distance from the bottom, convex of the bowl and the cap mounted to the air, this provided with Peripheral holes in its base, has internally coupled another bushing of lower height, whose flange sits through an elastic washer in the flange of the enclosure, the bushing being surrounded by a circular projection on its base, peripheral bores interior of said projection and traversed axially at its base by a small shank, faced by its head to that of the shank d e the bowl but separated from it, being arranged around its protruding portion of the convex face of the cap a very sensitive helical spring and coupled at the inner end a tiny capsule, on whose external base is attached an elastic disk, which under the Spring action tends to sit on the boss of the bushing and plug the holes in its base.
