A mixing valve receives water through a first inlet. The water is rotated by vanes in a first direction to produce a vortex. The water exits though an open end of a slidable tube, where it flows radially outward because of its rotational motion. The tube is axially movable by an actuator located near the open end of the tube, and the tube therefore acts as a steam shut off valve. Steam enters through a second inlet adjacent the open end of the tube, and is directed by vanes in an oppositely rotating vortex and radially inward by a conical surface just beyond the end of the tube. The steam and water mix at a location just beyond the end of the tube, and heated water exits through an axial opening which surrounds the actuator. The temperature of the water is regulated by the actuator.

[ What is claimed is:] [1.] Apparatus for mixing steam and water and delivering a stream of heated water, comprising:a tube extending along an axis and having an axial opening at one end;means for directing water into the interior of the tube and for establishing a first vortex of water circulating about said axis, both within the tube and beyond the axial opening;means for directing steam in a second vortex surrounding the tube, circulating about said axis and extending beyond said one end of the tube;means for directing the vortices into contact with each other, whereby the water and steam mix together to produce a stream of heated water, andmeans, responsive to the temperature of the heated water in said stream, for regulating the flow of steam through said directing means, and maintaining the heated water at a substantially constant temperature.
