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.
