    摘要: A device (1) for preventing overfilling of containers (B), in particular containers intended to contain liquefied gases, comprises:
    - a valve body (3) in which a gas pipe (5) is defined,
    - a closure means (7) axially movable in the valve body (3) away from and towards a valve seat (8) in order, respectively, to open and to shut off the gas pipe (5),
    - an actuator (16), comprising a float (20), capable of exerting a thrust (F) in order to urge the closure means (7) away from the valve seat (8),
    - a cam mechanism (21) for exerting the thrust (F) on the closure means (7) in an ascending phase of the float (20) until a preimposed limit position, corresponding to a maximum filling level, is reached,
    - a lever mechanism (26) for exerting the thrust (F) on the closure means in a first part of a descending phase of said float (20), starting from said limit position.
