Patent ID: 8353311

Claim:
An anti-flooding device comprising: a duct for passage of a flow of liquid; limiting means inserted along the duct and defining a section of passage of the liquid that decreases progressively as the flowrate of liquid increases, wherein the duct closes once a given threshold flowrate has been reached; an anti-flooding open/close element associated with said limiting means and an anti-flooding seat set along said duct for passage of liquid; wherein the limiting means comprise at least one male element and at least one female element, wherein the male element and the female element are mobile with respect to one another so that they slide into one another as the flowrate of liquid increases, progressive insertion into one another of said male element and said female element defining said section of passage; and wherein the male element and female element are shaped with respect to one another so as to reduce said section of passage as the flowrate of liquid increases, wherein the duct for passage of liquid closes as soon as a given threshold flowrate is reached.
