Title (EN) MIXING VALVE WITH A BALL CONTROL MECHANISM
(FR) VANNE MELANGEUSE A MECANISME DE COMMANDE DU TOURNANT
Abstract:
(EN) A mixing valve with a movable spherical valve element (14) with a guide mechanism which allows for rotation of the spherical valve element about its center along two different directions. The valve element (14) is provided with an opening (17) that cooperates together with inlet openings (10, 11, 12 and 13) for hot and cold water which are equipped with tubular seals (8) made from elastomeric material. The valve element (14) also has an outlet opening (16) for the mixed water located in a partially spherical seat in the fixed part of the faucet to control the proportion of the mixing between the hot and cold water and the flow of the mixed water. There are at least two openings (10, 11) for supplying the hot water equipped with tubular seals (8) and at least two openings (12,13) for supplying cold water with tubular seals (8). At least four openings (10, 11, 12 and 13) for supplying water are approximately located approximately along a great circle and circumferentially spaced about the semi-spherical seat. The opening (17) in the spherical valve element is elongated so that at least two openings are always fully uncovered in the full open position.
(FR) Une vanne mélangeuse à élément sphérique et amovible (14) comprend un mécanisme de guidage qui permet audit élément sphérique de tourner autour de son centre dans deux sens différents. L'élément sphérique (14) est doté d'un orifice (17) qui coopère avec des orifices d'entrée (10, 11, 12, 13) d'eau chaude froide munis d'éléments d'étanchéité tubulaires (8) en matériau élastomère. Ledit élément sphérique (14) possède également un orifice de sortie (16) d'eau mélangée situé dans un logement en partie sphérique qui se trouve dans la partie fixe du robinet et est destiné à régler le mélange d'eau chaude et d'eau froide ainsi que l'écoulement de l'eau mélangée. Au moins deux orifices (10, 11) servent au passage d'eau chaude et sont munis d'éléments d'étanchéité tubulaires (8), tout comme le sont au moins deux autres orifices (12, 13) qui servent au passage d'eau froide. Au moins quatre orifices (10, 11, 12, 13) servant au passage de l'eau sont approximativement situés sur un équateur, et sont espacés à la périphérie du logement semi-sphérique. L'orifice (17) qui se trouve dans ledit élément sphérique est allongé afin qu'au moins deux orifices soient entièrement découverts à tout instant et en position totalement ouverte.
