Abstract
A fluid mixing device includes a housing having two inlets for two fluids to be mixed, a common outlet, and a cylindrical chamber connecting the inlets to the outlet. A valve member is disposed within the cylindrical chamber and includes a cylindrical wall formed with a slot extending for a part of the wall circumference. The housing inlets include slots extending transversely of the cylindrical chamber. The valve member is displaceable axially for moving its slot into or out of alignment with the inlet slots. It is also presettable angularly to permit presetting the proportion the valve member slot is coextensive with the inlet slots, and thereby the proportions of the inletted fluids to be included in the outlet mixture. Also described is a demand valve optionally usable with the fluid mixing device.
