Abstract

Le problème décrit par la présente invention est de fournir un mécanisme sous vide qui a un effet de non-retour principal pour empêcher l'entrée d'air, et un effet d'accompagnement consistant à empêcher l'égouttement d'une gouttelette de liquide (phénomène d'égouttement) adhérant à un orifice d'évacuation lorsqu'un liquide dans un récipient est évacué, puis le récipient est à nouveau debout, le mécanisme sous vide étant en outre équipé d'un mécanisme de réglage de débit conçu pour ajuster le diamètre interne d'un clapet de non-retour pour permettre le réglage du débit du liquide pendant l'éjection. La solution selon la présente invention porte sur un mécanisme sous vide équipé d'un mécanisme de réglage de débit, et comprenant un clapet de non-retour dans lequel une découpe est disposée dans une partie d'arc d'extrémité de pointe d'un corps cylindrique et qui est pourvue d'une partie de ressort en forme de film au niveau d'une partie arrière du corps cylindrique, caractérisé en ce qu'un élément de commande cylindrique pour ajuster le diamètre interne du corps cylindrique est fixé au corps cylindrique.
