Automatic air outlet valve, characterized by being constituted by a piece that can be embedded in a floor, wall or any other appropriate element, for which purpose it has been planned to provide it with external projections for its better support. The inner part forms a cavity or container in whose mouth it has an internal thread to receive and fix a bushing. The threaded part of this bushing, which is the one that penetrates the mentioned container, ends in a conical crown. The upper part forms a void or box in which a spring or spiral is housed. Crossing the turns of this spring, there is an axis or piston that on the outside is joined to a bowl of larger diameter than the assembly and that, as a cover, forms the button. On the inside it ends in a circular piece on which a washer or rubber gasket is placed. (Machine-translation by Google Translate, not legally binding)
