Multiple flow rate fluid control valve assembly
First Claim
1. A multiple flow rate fluid control valve assembly in which the mode of fluid flow is interfaced with the rate of fluid flow, the assembly comprising:
- a first valve having a plurality of selectable flow modes including a continuous fluid flow mode and a pulse fluid flow mode, and a switch for selectively setting the valve to one of the plurality of selectable flow modes, anda second valve connected to the first valve having structure to permit selectively controlling the rate of fluid flow from a source of fluid through the second valve to the first valve, thereby to provide fluid from the source of fluid to the first valve at a rate which is appropriate for the mode of fluid delivery selected and the particular fluid use.

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.

11. A multiple flow rate fluid control valve assembly in which the mode of fluid flow is interfaced with the rate of fluid flow, the assembly comprising:
-
a first valve having a switch for selectively setting the valve to one of a plurality of selectable flow modes, and a second valve connected to the first valve for selectively controlling the rate of fluid flow from a source of fluid through the second valve to the first valve, thereby to provide fluid from the source of fluid to the first valve at a rate which is appropriate for the mode of fluid delivery and the particular fluid use, wherein the first valve further comprises a shaft connected to the switch in such manner that the shaft is caused to be moved within the valve when the switch is moved to thereby cause the flow mode of the first valve to be changed from any one of the modes to another, and further wherein the first valve has a body which defines at least two inlet ports and at least one outlet port, the inlet ports being disposed one above the other on the body, and the at least one outlet port being disposed substantially perpendicular to the inlet ports at a position longitudinally substantially equally between the at least two inlet ports. - View Dependent Claims (12, 13)

14. A multiple flow rate fluid control valve assembly in which the mode of fluid flow is interfaced with the rate of fluid flow, the assembly comprising:
-
a first valve having a switch for selectively setting the valve to one of a plurality of selectable flow modes, and a second valve connected to the first valve for selectively controlling the rate of fluid flow from a source of fluid through the second valve to the first valve, thereby to provide fluid from the source of fluid to the first valve at a rate which is appropriate for the mode of fluid delivery and the particular fluid use, wherein the second valve is a flow rate control valve having an upper body portion and a lower body portion connected to the upper body portion, and a flow control plate rotatably mounted between the upper body portion and the lower body portion, the flow control plate having a plurality of tracks of apertures of graduated size for selectively controlling the amount of fluid which can pass therethrough as the fluid is transferred from the second valve to the first valve. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)

23. A multiple flow rate fluid control valve assembly in which the mode of fluid flow is interfaced with the rate of fluid flow, the assembly comprising:
-
first valve means having means for switching, for selectively setting the first valve means to a preselected one of a plurality of optional fluid flow modes, including a pulse fluid flow mode and a continuous fluid flow mode and second valve means connected to the first valve means and to a source of fluid for selectively controlling the rate of fluid flow from the source of fluid through the second valve means to the first valve means, thereby to provide fluid from the source of fluid to the first valve means at a rate which is appropriate for the mode of fluid delivery selected and the fluid use.
