  • Patent number: 8286831
    Abstract: A dispenser 10 creates a use solution. The dispenser 10 includes a diluent inlet for receiving a source of diluent. A first aspirator 38 is in fluid communication with the diluent inlet. An operator valve 27 controls flow of the diluent. A second aspirator 46 has a diluent inlet, diluent outlet and a venturi port. A vacuum switch 63 is operatively connected to the first venturi port and the flow of the diluent through the aspirator 46 creates a vacuum that activates the vacuum switch. A control board 69 is activated by the vacuum switch and a dosing pump 76 is activated by the control device 69.
