An automatic valve for balls and balloons, which is constituted by an enclosing body coupled by its base to the chamber and which is completely inside said chamber, which is perforated internally with various sections, one provided with internal thread for the coupling of the coupling, a valve seat with a central hole and a cavity for the housing of the valve itself, which is constantly pressed against its seat by means of a spring that rests on the inner end of the valve body, presenting the valve itself a stem that protrudes from the side of the seat and is inserted, when pressed, in the central hole of said seat, being necessary to leave free passage to the air, press this protruding tip, overcoming the pressure of the spring, to which end the valve is complemented with a fitting provided with an external thread for the coupling, which has at its base a protruding cent This is done so that when the coupling is screwed down, the tip of the piston rod is pressed, and a valve is used to retain and block the passage of air when passing or retracting the piston of the pump.
