Abstract
A thermostatically controlled mixing valve having a modular cartridge mounted in a housing. The cartridge comprises a tubular sleeve having rotatably disposed therein a hollow cylindrical housing. The bottom of the cylindrical housing has a volume control valve plate attached against rotational movement thereto. The volume control valve plate cooperates with a fixed valve plate with which it is in surface-to-surface contact to control the volume of water flowing into the cartridge. The fixed valve plate is affixed against rotational movement to a nose piece which is fixedly attached to the bottom of the tubular sleeve. An inner housing is disposed within the hollow cylindrical housing and defines therewith cold and hot water inlet passageways which are in communication with a mixing chamber in the interior of the inner housing through hot and cold water supply openings.
A thermostat construction responsive to the mixed water temperature is axially movably disposed in the mixing chamber and is operably connected to valving means adapted to open and close the hot water supply opening and cold water supply opening. The valving means comprise a cylinder fixedly mounted on the top of the inner housing with the bottom of the cylinder and the top of the inner housing defining the hot water supply opening, and with the top of the cylinder defining with an inner shoulder in the cylindrical housing the cold water supply opening, and a piston operably connected to said thermostat construction and axially slidably disposed in said cylinder. Upward movement of the piston in the cylinder serves to close off the cold water supply opening while downward movement of the piston serves to close off the hot water supply opening. An increase in the mixed water temperature in the mixing chamber results in axially downward movement of the thermostatic element with consequent downward movement of the piston thereby resulting in restriction or closure of the hot water supply opening. A decrease in the mixed water temperature in the mixing chamber results in axially upward movement of the thermostatic element with consequent upward movement of the piston thereby resulting in restriction or closure of the cold water supply opening thereby maintaining a preselected water temperature in the mixing chamber.
