| 摘要 |
<p>The invention relates to an anti-flooding device (10) comprising a duct (12) for passage of a flow of liquid, and limiting means (14) inserted along the duct (12) for passage of liquid and defining a section for passage of the liquid that decreases progressively as the flowrate of liquid increases, with closing of the duct (12) once a given threshold flowrate has been reached. The limiting means (14) comprise at least one male element (18) and at least one female element (20), which 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 (18) and said female element (20) will define the section of passage. The male element (18) and female element (20) are shaped with respect to one another so as to reduce the section of passage as the flowrate increases, with closing of the duct (12) for passage of liquid as soon as a given threshold flowrate is reached.
