Abstract
A proportioning dispenser of concentrated chemical mixed in a diluent such as water includes a water valve, an in-line water pressure regulator downstream of the valve and an eductor downstream of the regulator. When the valve is open, water flows to the regulator, and a pressure regulator water flow passes to the eductor. When the valve is closed, no water flows to the regulator, which sees pressurized water only when the water valve is open during a dispensing cycle. More accurate dilution ratios are achieved over a wide range of incoming water line pressures. In an alternate embodiment, a water valve and a regulator are formed in a common housing with the regulator operationally downstream of the valve.
