Abstract
A detergent dispenser that is coupled to a source of fluid and which has a chemical source in solid cast form. A spray generator is designed to generate a fluid spray bearing on the chemical source, the fluid spray generating a concentrated solution of the chemical. The concentrated solution of the chemical is discharged through a discharge conduit. A single valve controls a flow of fluid from the source of fluid. The valve has an inlet that is operably fluidly coupled to the source of fluid, an outlet that is operably fluidly coupled to the spray generator, and an outlet that is operably fluidly coupled to the discharge conduit. A metering device for selectively metering portions of the flow of fluid to the spray generator and to the discharge conduit is disposed within the valve and selectively fluidly couples the inlet to the outlet that is operably fluidly coupled to the spray generator and to the outlet that is operably fluidly coupled to the discharge conduit. A pressure feedback shutoff system is utilized to ensure that fluid flow to the spray generator is disabled at the time that the flow in the discharge conduit is disabled.
