Improved valve, characterized in that it is constituted by a semi-rigid discoidal body, which presents in the center towards one of the faces a pronounced depression that ends in a truncated cone shape, whose hollow determined by said depression presents a small narrowing in the part corresponding to the embouchure, while the free base of the frustoconical projection is provided with small holes, including within said body a flexible membrane, which has a correlative configuration to the interior of said body depression, in coincidence with the frustoconical projection thereof. The inner part, but said membrane being completely closed at the end of its corresponding central projection, while in the free edge thereof there are distributed in the peripheral contour a series of small radial prominences, with which it fits inside the narrowing from the embouchure of l to depression of the semi-rigid body, so that when pressure is exerted by the open part of the aforementioned central depression of the assembly, the closing of the valve occurs by itself, opening it when a greater pressure acts on the opposite side.
