Abstract
A compensating valvular apparatus for supplying air in the breathing apparatus for autonomous divers, disposed in a box that communicates permanently with the source of fluid supply that is to be controlled, which opens in the opposite direction to the jet of said fluid outside of the box and characterized by the fact that the diameter of its shank is, in principle, equal to the diameter of the orifice controlled by the valve and said shank leaves the box through, at least of an O-ring seal, to penetrate in a cavity in which the pressure is equal to the pressure in the outlet duct controlled by the valvular device, when the valve is closed.
