Abstract: A mechanical device for checking the level to which cylinders and the like are filled with liquid gases, comprising a feeder pipe anchored to the cutoff valve unit of the cylinder. At the lower end of the pipe there are provided openings which are connected to the inside of the cylinder and in a front region there is provided a closure membrane made of flexible material and centrally provided with at least one through hole. The membrane is peripherally locked between the rim of the end of the tubular element and a hollow body which is anchored coaxially to the feeder and is provided, in an upward region, with a cavity which allows the membrane to deform correspondingly in order to directly connect the free end of the tubular feeder body to the lateral openings thereof. The hollow body has a cavity which is coaxial to the hole of the membrane and leads into a chamber in which there is provided a shutter body movable axially by means of a cam which is associated with a floating device. In this way, during the filling of the cylinder, the membrane is allowed to deform under the pressure of the gas being fed, making it flow out into the cylinder and, in small amounts, through the holes of the membrane and of the cavity of the hollow body. In the same way, once the level has been reached, the floater is allowed to arrange the cam so that the shutter can close the end of the hollow body, so as to allow the membrane to move to a stable closure position on the end of the feed pipe by means of the counterpressure generated by the gas that acts on different areas of the two opposite sides of the membrane.
