Abstract
A buoy-holder head, which is characterized by being formed by a prismatic body with six faces, in one of whose smaller bases it has the two corresponding circular holes in parallel: one to the introduction and connection of the upper end of the snorkel and the other to give way to the assembly of the sealing sphere of the valve, essentially comprising within it the distribution of three compartments, in vertical position such as: a cylindrical conduit for the reception of the tube, another analogous conduit parallel to the first constituted of the space in which the said spherical buoy oscillates freely and a third and transverse top that composes the air passage chamber, this chamber possessing in its internal partition the two holes corresponding to the compartments mentioned as lower.
