Abstract

Vanne de régulation antibélier et réduisant le bruit, qui comporte un logement (1) doté d'un orifice d'entrée (2) et d'un orifice de sortie (3). La partie taraudée (4) permet l'installation du corps sur l'orifice de sortie d'un robinet. La partie filetée (5) permet la connexion d'un dispositif consommateur d'eau à l'orifice de sortie (3). Un siège (6) de vanne en combinaison avec un corps (7) de vanne permet au fluide de s'écouler librement de l'orifice d'entrée (2) à l'orifice de sortie (3) du logement (1) et un ressort (8) en conjonction avec une plaque (9) de position provoque une forte restriction sur le fluide essayant de s'écouler de l'orifice de sortie (3) à l'orifice d'entrée (2). Des passages (10) de flux ménagés dans la plaque (9) de position permettent la libre circulation du fluide. Un dispositif (11) de position maintient la plaque (9) de position en place à l'intérieur du logement (1).
