CA 2261148

An additive dispensing apparatus for a fluid system is disclosed which includes a head having a body portion (11) adapted and configured for fluid communication with the fluid system and having a flow path extending therethrough. A fluid inlet portion (14) of the flow path defines a relatively high pressure region and a fluid outlet portion (16) of the flow path defines a relatively low pressure region. A canister is operatively associated with the body portion and structure is provided for facilitating fluid communication between the fluid inlet portion and the interior of the canister. A collapsible container (22) is disposed within the canister for containing a liquid additive for dispensment into the fluid system and structure is provided for facilitating fluid communication between the collapsible container and the fluid outlet portion, whereby the differential pressure between the interior of the canister and the interior of the collapsible container effectuates a proportional dispensment of liquid additive into the fluid system.

L'invention concerne un appareil de distribution d'additif pour un circuit de fluide. Ledit appareil comporte une tête dont une partie du corps (11) est conçue et configurée pour être en communication fluidique avec le circuit de fluide et qui est traversée par un passage d'écoulement. Une partie entrée de fluide (14) du passage d'écoulement définit une région de pression relativement élevée et une partie sortie de fluide (16) de celui-ci définit une région de pression relativement faible. Un contenant est associé de manière active au corps et une structure est prévue pour faciliter la communication fluidique entre la partie entrée de fluide et l'intérieur du contenant. Un réservoir repliable (22) est placé à l'intérieur du contenant, pour contenir un additif liquide à distribuer dans le circuit de fluide et une structure est prévue pour faciliter la communication fluidique entre le réservoir repliable et la partie sortie de fluide, la pression différentielle entre l'intérieur du contenant et l'intérieur du réservoir repliable entraînant la distribution proportionnelle d'additif liquide dans le circuit de fluide.
