The dispenser comprises an eductor for the drawing of a concentrate fluid from a liquid reservoir container into an input carrier fluid by means of the flow of the other fluid utilizing a venturi effect. In this dispenser the concentration of the concentrate fluid in the input fluid can be varied to differing preset amounts. The dispenser contains an elongated channel having an input for the input fluid and dispensing nozzle at an exit end for dispensing the chemical concentrate fluid in a diluted form. There is a transverse intersecting channel intermediate the input end and the exit end. The transverse intersecting channel has an insert that is moveable in the intersecting channel, apertures of the moveable insert being alignable with apertures in the transverse intersecting channel and the liquid reservoir container holding the concentrate fluid. One aperture is in alignment with the elongated channel and another aperture in alignment with a channel from the liquid reservoir container. The channels from the liquid reservoir container will have a plurality of various sized apertures to provide for the flow of differing amounts of chemical concentrate fluid into the input fluid at a given input fluid flow rate. This results in a product stream of the input fluid diluted to a set concentration. By adjusting the moveable insert in the transverse intersecting channel and/or the input fluid flow rate the concentration of the chemical concentrate in the product fluid is changed. |
