Abstract
Automatic valve for air chambers, consisting essentially of an externally threaded cylindrical body, inside which can be moved a rod carrying an elastic washer intended to fit against a concave seat formed between the inner cavity of the valve and the smaller diameter duct formed in the opposite class to the coupling, whose stem is guided inside this valve by a circular piece integral with it, which moves loosely as a piston, on which piece is mounted the sealing elastic element, being provided in the mouth of the coupling base of a perforated or open washer that acts as a guide for the central stem, between this washer and the integral part of the latter comprising a coil spring tending to keep closed; the valve when pressing the obturator against the indicated seat.
