Abstract: A mixing valve includes the volume control valve, a pressure proportioning valve, and a thermostatic valve assembly within a single modular housing. The housing is rotatably mounted in a valve body. The housing houses the proportioning valve and the thermostatic control valve. Rotation of the housing controls the total volumetric flow from the supply inlets of the valve plate at the end of the housing. The thermostatic control valve includes a pivotable lever which has a spring seated at one side and a thermally responsive wax element at the other side with the fulcrum of the lever between the spring and wax element. Control handles are mounted at the end of the valve to independently control the volume and the temperature. An annular discharge chamber surrounds the housing section which houses the proportioning valve. The discharge chamber is in fluid communication to an outlet which is located at the same end of the valve body as the hot and cold water inlet supply lines.

Abstract: A mixing valve (10) has a modular cartridge (60) rotatably mounted in housin (12). The cartridge has a bottom volume control valve plate (58) attached to a lower section (62) housing a pressure balance valve (80). The lower section (62) is secured to an upper section (120) that rotatably receives a temperature control plate (150). The plates (58) and (150) are both rotatable about a common axis (64). The plate (58) is controlled by operation of stem (180) attached to handle (34). The plate (150) is controlled by stem (160) which is operated by knob (38). An insert (250) allows the knob (38) to operate even when hot and cold water supplies are inverted. A splined hot water stop ring (228) sits in handle (34) and adaptably limits rotation of knob (38) for a selected maximum water temperature. Outer seals (58) assure that all water flows through cartridge (60) when the volume is set for partial flow.

Abstract: A diverter tub spout for use in a bathtub installation including a shower head interconnected to a common source of water. A floating valve member is positioned within the spout water passage and is responsive to water pressure to abut a valve seat to close the passage. A valve control member capable of holding the valve member remote from the seat to permit water flow is held in the flow position by a manually operable stem in a manner that positively allows water flow regardless of the magnitude of water pressure. The stem easily may be positioned to allow the floating valve to close, diverting water from the spout to the shower head, but upon the water pressure dropping below a predetermined level, the tub spout parts will automatically return to their flow positions.
