Abstract

A pressure-valve, decompression that is characterized by being constituted by a cylindrically hollow body in which a head is determined from which a tail of longer length and smaller external diameter than that, starting configured in its cylindrical central hollow in order from the upper edge of said head, a first landing to which at a certain distance and narrowing the diameter of the hole follows an annular prominence that carrying practiced one or more transverse conduits that communicate the internal enclosure with the environment, is determinative of two other equal and opposite landings, to which prominence follows a widening of diameter to the end of the tail, of which landings: the one closest to the end of the head, limits in depth the space in which the maneuvering button is contained; the upper of the two equal and opposite that determines the mentioned annular prominence, is support of a helical spring that reacts against the lower face of said maneuver button and acts as a stop that limits the inward movement of said button and its annexes; and the lower of the two equal and opposite that determines the aforementioned circular prominence, is the support base of an elastic washer in seat functions of a valve attached to the end of a pin attached to the maneuver pushbutton, all appropriately so that when the maneuvering pushbutton in its static position, forced by the action of the helical spring acting on it, the valve is adapted to its seat or in the closed position, and when pressing on the maneuvering button, the displacement of the valve, this one opens, producing the desired decompression through the conduits practiced in the aforementioned annular prominence.
