초록

Disclosed is a fluid dispensing system for precisely controlling the mixing of a first fluid (i.e., a diluent such as water) with a second fluid (i.e., a concentrate) at a mixing point within the fluid dispensing system. A valve is positioned in the dispensing system along the line of supply of the second fluid upstream of the mixing point, such valve being simultaneously actuated through application of positive and/or negative pressure to allow the second fluid to flow through the valve. The application of positive and/or negative pressure is generated ...
