Abstract:
1. A dispenser for mixing a diluent and at least one chemical to form a mixed effluent and for discharging said effluent through at least one common discharge tube, said dispenser comprising: at least two selectable eductors; each of said eductors operatively coupled to at least one chemical source for drawing chemical into a diluent, selectively passing through each said eductor; a common discharge tube; each eductor operatively coupled to said common discharge tube; each eductor selectively discharging an effluent of mixed chemical and diluent into said common discharge tube operatively connected to each of said eductors; discharge of effluent from a selected eductor being insufficient to cause flow of effluent from a selected eductor to a chemical source coupled to a non-selected eductor and being insufficient to draw chemical from a non-selected eductor into said effluent; said dispenser further including a second discharge tube and wherein at least a third eductor is constructed to produce a different effluent flow rate than said at least two eductors, said third eductor operably connected to said second discharge tube; and wherein each eductor includes an effluent deflecting member for causing flooding of each eductor upon passage of a diluent therethrough and wherein the effluent deflecting member of said at least two eductors varies in shape from the effluent deflecting member of said third eductor.
