Controlled inflator, essentially characterized because between the arrangement of a check valve and the air outlet to the outside of the inflator, a chamber is constituted with a pressure equal to that of the tubular to which air is being blown, in whose chamber a closed assembly is housed that communicates with the camera through a sliding cylinder in a conduction carried out in the aforementioned assembly, a cylinder that must overcome the force of a pre-calibrated spring, and that involves metallic contacts that establish physical contact with the corresponding ones of a printed circuit by batteries, with which small lamps or side related to the printed circuit are lit, each of the lamps corresponding to a predetermined pressure to be reached in the tubular.
