Abstract

L'invention a pour objet un distributeur de volumes dosés d'un liquide. Ce distributeur comporte au moins trois ensembles de dosage comportant chacun une chambre de dosage obturée par une membrane déformable et un piston solidaire de la membrane, une came et des moyens d'entraînement en rotation de la came autour d'un de ses points 0, les pistons étant répartis autour du point 0, dans le plan de la came, à intervalles angulaires constants et en contact avec la came, ladite came presentant un arc de cercle de centre 0 et d'angle au centre egal à l'angle entre deux pistons consécutifs, cet arc étant relié tangentiellement par chacune de ses extrémités à une courbe telle qu'un volume dosé de liquide soit véhiculé entre les chambres et refoulé de la dernière chambre pour une rotation de 2 pi de la came, chacune des chambres étant telle qu'elle soit obturée de façon étanche lorsque le piston est en contact avec l'arc de cercle de la came. Application à la distribution de produits corrosifs.
