Abstract

L'invention concerne un système pour préparer une section transversale d'étranglement (1) pour un flux de fluide. La section transversale d'étranglement (1) peut varier en fonction d'une différence de pression sur celle-ci. À cet effet, le système est conçu de manière à pouvoir inverser la polarité de la différence de pression au moyen de laquelle la section transversale d'étranglement peut varier. Il est ainsi possible d'utiliser le système selon l'invention pour des flux de fluide dont le sens d'écoulement change.
