Abstract

On décrit un mélangeur de fluides du type fixe peu coûteux qui empêche l'interruption du mélange dû à un écoulement court-circuité au moment du mélange de fluide et qui est facile à utiliser et à assembler. Le mélangeur de fluides de l'invention comprend deux sièges (18) de joint formés dans des disques de grand diamètre situés sur des éléments mélangeurs (5, 5a) disposés dans un carter, des éléments (35) de joint montés dans des rainures (34) d'étanchéité qui sont formées par les sièges (18) de joint, et un premier groupe de petites chambres (13) de mélange et d'un deuxième groupe de petites chambres (15) de mélange qui sont formées monobloc et composées d'une multiplicité de petites chambres (12, 12a) présentes dans les éléments mélangeurs (5a).
