Abstract

L'invention concerne une buse à obturation pour jet de liquide comprenant un logement (1) présentant un orifice d'entrée (2) de liquide et un orifice de sortie (3) de liquide, et un corps de formation de jet (6) pouvant être entouré par un écoulement et agencé dans le logement, lequel corps est pourvu d'une zone d'extrémité (9) rétrécissant en direction de l'orifice de sortie (3) de jet. Un canal d'écoulement (10) annulaire est formé entre le logement (1) et le corps de formation de jet (6) sur au moins une partie de la longueur axiale dudit corps. Une membrane annulaire (12) élastiquement déformable, raccordée durablement et de manière étanche au logement (1) par sa périphérie extérieure (13), est agencée dans le canal d'écoulement (10) annulaire. En l'absence d'amenée de liquide à l'orifice d'entrée (2) de liquide, ladite membrane s'applique extérieurement contre le corps de formation de jet (6) par sa périphérie intérieure (19), la périphérie intérieure (19) de la membrane annulaire (12), lors de l'amenée de liquide à l'orifice d'entrée (2) de liquide, se soulevant du corps de formation de jet (6) et libérant un orifice de passage annulaire.
