The valve arrangement may beused to mix two fluids. The two fluids arrive separately and enter inlet pipes (1) facing each other so that the two streams of fluid flow towards each other. The mixture leaves via a single side branch (3). A mechanical or electrical valve control arrangement may be used. The mechanical system has two throttle valves (7) in the inlet pipes (1), linked together by a rod (6) passing through a membrane (5). The membrane acts to move the rod and the valves to equalise the pressure on either side of the membrane. There is a side branch on either side of the membrane. Each side branch has its own throttle valve (2), and these valves are set to regulate the proportions of the two constituents coming together in the blending chamber just downstream of the valves. L'INVENTION CONCERNE UN DISPOSITIF MELANGEUR POUR ASSURER UN MELANGE CONTINU D'AU MOINS DEUX LIQUIDES, NOTAMMENT POUR DES MACHINES DE PREPARATION DE LIQUIDE A PULVERISER, CE DISPOSITIF MELANGEUR COMPORTANT UN NOMBRE DE CONDUITS D'ADMISSION CORRESPONDANT AU NOMBRE DES LIQUIDES A MELANGER, UNE UNITE DE REGULATION DE LA PROPORTION DE MELANGE ET UN VOLUME MELANGEUR DEBOUCHANTDANS UN CONDUIT COMMUN DE DECHARGE; IL EST PREVU DANS LES CONDUITS D'ADMISSION 1, IMMEDIATEMENT AVANT L'UNITE DE REGULATION DE LA PROPORTION DE MELANGE 2, UN DISPOSITIF 5 DETECTANT LA DIFFERENCE ENTRE LES PRESSIONS DES DIFFERENTS LIQUIDES CONSIDERES PAR PAIRES, AINSI QU'UNE UNITE 7 COOPERANT AVEC CE DISPOSITIF ET REGLANT LES PRESSIONS A LA MEME VALEUR.
