Abstract
A surface respirator, perfected, since it is constituted by a normal tube, whose base bent at an angle, is inserted in a valve body in the form of a circular box that on one side has a projection, to which the final expulsion valve corresponds, and on the opposite side, it extends into a cylindrical channel at the end of which the rubber bit is inserted into the mouth of the user, the inside of this body being separated into two compartments, by means of a transverse partition, which leaves on the side smaller or of the mouthful, the orifice and mouthpiece through which the tube that comes from the outside air penetrates, and in the greater side a second circular central box, closed and isolated, held concentrically by support flanges, which occupies most of the compartment, and determines the existence of a department that is destined to be filled with the water coming from the flood that produces the total immersion of the tube.
