Abstract

Ce robinet est caractérisé par les relations suivantes, pour un diamètre de tubulure d'entrée supérieur ou égal à 6 mm : a) le contact d'étanchéité entre le clapet 3 et le siège 2 s'effectue suivant une quasi-arête 12 ayant au plus 2 mm de largeur; b) le clapet et le siège définissent entre eux un angle alpha compris entre 10o et 80o; c) la tubulure d'arrivée 7 se termine par un arrondi 11 dont le rayon rs est compris entre 0,5 et 3 mm; d) le diamètre intérieur diamétre ch de la chambre 5 dépasse d'au moins 5 mm le diamètre diamétre e de la tubulure d'entrée 7 augmenté de deux fois le rayon rs dudit arrondi; et e) le diamètre extérieur diamétre c du clapet 3 ne dépasse pas de plus de 20 mm le diamètre diamétre e de la tubulure d'entrée 7 augmenté de deux fois le rayon rs dudit arrondi. Un tel robinet est particulièrement silencieux aux débits élevés, pour un diamètre donné de la tubulure d'arrivée
