Patent ID: 7293582

Claim:
A mixing valve, comprising: a first and second diaphragm control valve, operatively attached to a manifold; the manifold including a body defining a first fluid inlet, a second fluid inlet, a fluid outlet, a first diaphragm chamber for operative attachment thereto of the first control valve, a second diaphragm chamber for operative attachment thereto of the second control valve, and an outlet conduit; the first diaphragm chamber of the manifold including an inlet and a valve seat thereof, with the valve seat defining the outlet of the first diaphragm chamber, the outlet of the first diaphragm chamber being disposed within the valve seat of the first diaphragm chamber, the inlet of the first diaphragm chamber being disposed outside of the valve seat, within the first diaphragm chamber, and connected in fluid communication with the first fluid inlet; the second diaphragm chamber of the manifold including an inlet and a valve seat defining an outlet of the second diaphragm chamber, the outlet of the second diaphragm chamber being disposed within the valve seat of the second diaphragm chamber, the inlet of the second diaphragm chamber being disposed outside of the valve seat, within the second diaphragm chamber, and connected in fluid communication with the second fluid inlet; the outlet conduit of the manifold having an outlet thereof connected to the fluid outlet, a mixing chamber adjacent the outlet and a divided intermediate second thereof disposed between the mixing chamber and the outlets of the first and second diaphragm chambers; the divided intermediate segment of the outlet conduit having an imperforate septum wall therein, dividing the inlet section of the outlet conduit into a first and a second fluid passage, the first fluid passage being connected in fluid communication between the mixing chamber and only the outlet of the first diaphragm chamber, and the second fluid passage being connected in fluid communication between the mixing chamber and only the outlet of the second diaphragm chamber, the first fluid passage extending substantially parallel to a plane defined by the septum wall, the outlet conduit further including a lateral portion extending between and fluidly communicating the outlet of the second diaphragm chamber and the second fluid passage, wherein the lateral portion extends transverse to the septum wall; and wherein the first diaphragm chamber of the manifold includes a wall thereof separating the first diaphragm chamber from the second fluid passage of the divided intermediate segment of the outlet conduit.
