Abstract

L'invention concerne un limiteur de débit silencieux. Il comporte plusieurs pièces étroitement ajustées dans lesquelles des trous sont percés. Les pièces sont ensuite décalées l'une par rapport à l'autre, de manière que les trous se chevauchent partiellement, formant ainsi des orifices limiteurs suivis par des chambres d'expansion. L'invention s'applique notamment à des vannes à haute pression et à des plaques de contre-pression .
