Abstract
A multiple flow rate fluid control valve assembly in which the mode of fluid flow is interfaced with the rate of fluid flow has a mode control valve having a switch for selectively setting the valve to either of a continuous fluid flow mode or a pulse fluid flow mode. A fluid flow rate control valve is connected to the mode control valve for selectively controlling the rate of fluid flow from a source of fluid through the rate control valve to the mode control valve, to thereby provide fluid from the source of fluid to the mode control valve at a rate which is appropriate for the mode of fluid delivery and the particular fluid use.
