<p>A mixing valve assembly comprises a body portion having a cylindrical bore extending therethrough and a pair of entrance channels for the admission of two dissimilar fluids (e.g. hot water and cold water), each such channel communicating with the bore through an opening in the wall of the bore. A mixing control member having a cylindrical plug is mounted with said plug in the bore of the body member and rotatable therein. The mixing control member further includes a mixing chamber, two separate inlet passages discharging into the mixing chamber, and an outlet passage discharging from the mixing chamber. Each inlet passage is movable with rotation of the plug in the bore from a closed position to an open position with respect to one of the openings in the wall of the bore. A valve seat is formed at the discharge of the inlet passages, and a valve engageable with the seat is provided. By rotation of the mixing control member in the bore of the body portion, the relative proportion of dissimilar fluids that may flow to the mixing chamber through the inlet passages is regulated, and by operation of the valve the total volume of such fluids that may enter the mixing chamber is controlled.</p> |
