Abstract (en)
[origin: WO03096133A1] Disclosed is a fluid dispensing system for precisely controlling mixing of a first fluid (i.e., a diluent such as water) with a s econd fluid (i.e., a concentrate) at a mixing point within the s ystem. A valve (10) is positioned in the system along the line ofsupply (501) of the second fluid upstream of the mixing point (701), such valve (10) being simultaneously actuated through applic ation of positive and/or negative pressure to allow the second fluid to flow through the valve (10). The pressure is generated fr om the first fluid to be dispensed by the system and mixed with the second, such that the termination of flow of the first fluid immediately terminates flow of the second fluid to ensure proper mixing of the two fluids in the final solution, thus preventing inadvertent leakage of the second fluid or collection of the second fluid within the flow system which may become subject to spoila ge or contamination.
