  • Patent number: 11815919
    Abstract: A plural component dispensing system includes a dispensing device, first and second fluid component sources, a system controller, and an operator interface device. The first fluid component source is connected to the dispensing device to deliver the first fluid component to the dispensing device. The second fluid component source is connected to the dispensing device to deliver the second fluid component to the dispensing device. The system controller is connected to regulate operation of the first fluid component source and the second fluid component source to produce a target ratio of the first fluid component and the second fluid component at the dispensing device. The operator interface device is remote from and operatively connected to the system controller. The operator interface device is configured to output system state information received from the system controller and to receive operator input to control an operational state of the system controller.

  • Patent number: 10245607
    Abstract: A fluid dispensing system includes a pump, a valve, and a dispenser disposed downstream of the valve and connected to the valve with a hose. To provide a steady flow rate at the dispenser, the pump charges the fluid to or above the pressure required to achieve a desired flow rate. The valve cycles between open and closed at a fixed frequency. The valve-open time is varied within that frequency to maintain the desired flow rate.

  • Patent number: 10162370
    Abstract: A plural component dispensing system 10 receives separate fluid components, mixes the components in a predetermined ratio, and dispenses the components as mixture. Each fluid component is supplied by a separate pump 12A, 12B to an individual variably controllable fluid regulator 14A, 14B. Each fluid component is supplied from its individual fluid regulator 14A, 14B through a flow meter 18A, 18B to a mixing device 20. The ratio of the components delivered to the mixing device 20 is controlled by the individual fluid regulators 14A, 14B based upon the flow rates measured by the flow meters 18A, 18B.
