Abstract

Générateur de vide comprenant une grappe de cellules venturis multi-étages comportant chacune une buse assujettie de manière étanche dans un orifice d’entrée d’un premier mélangeur pourvu d’un premier orifice d’aspiration, et un deuxième mélangeur fixé au premier mélangeur de manière à ce que le deuxième mélangeur s’étende coaxialement au premier mélangeur et soit espacé d’un orifice de sortie dudit premier mélangeur pour former avec celui-ci un deuxième orifice d’aspiration, caractérisé en ce que les premiers mélangeurs sont reliés solidairement entre eux par une première membrure s’étendant entre les premiers orifices d’aspiration et les orifices de sortie des premiers mélangeurs de manière à former une première portée d’étanchéité entourant lesdits premiers mélangeurs, et les deuxièmes mélangeurs sont reliés solidairement entre eux par une deuxième membrure s’étendant entre des orifices d’entrée et des orifices de sortie des deuxièmes mélangeurs de manière à former une deuxième portée d’étanchéité entourant lesdits deuxièmes mélangeurs.
