A temperature control apparatus is provided, which is capable of, even when it is necessary to perform control by means of valves in a plurality of channels, promptly controlling a temperature of an area to be temperature-controlled promptly to a desired temperature, while avoiding complication and enlargement of the apparatus as a whole. Passage and blockage of a heating medium passing through a first supply channel to a mixing channel, a temperature of the heating medium being controlled by a first temperature regulating unit at a predetermined temperature, and passage and blockage of a heating medium passing through a second supply channel to the mixing channel, a temperature of the heating medium being controlled by a second temperature regulating unit, are controlled by a valve unit. The valve unit includes a first spool valve and a second spool valve, which are coupled through a heat insulating layer.

A plumbing fitting includes a housing and a missing valve. The housing includes a first aperture, a second aperture, a third aperture, and a mixing chamber in fluid communication with the first aperture, the second aperture, and the third aperture. The mixing valve is disposed within the housing. The mixing valve includes a first flow control valve that is configured to control a first flow of fluid from the first aperture to the mixing chamber.

The invention relates to a thermostatic mixing valve with integrated flow diverter provided with a first coupling for a control lever for the flow rate adjustment and the flow diversion through a valve group that is housed between a base and a cylindrical body, and with a second coupling for a knob for the temperature adjustment through a thermostatic device, said valve including a member for the transmission of the flow rate adjustment and flow diversion control that directly connects the control lever to the valve group passing through the cylindrical body without moving it, the latter being also enclosed within an external casing secured to the base and achieving a watertight sealing with the base.

A mixing valve includes a mixing chamber, a first flow control valve having a first flow control opening, and a second flow control valve having a second flow control opening. The first and second flow control openings each have a diameter of approximately six millimeters and the mixing valve has a flow coefficient of approximately 2.5 when both flow control valves are in a mid-open position.

A mixing valve that includes a housing having a first outlet, a second outlet, and a mixing chamber; a first flow control valve for controlling flow through the first outlet to the mixing chamber; and a second flow control valve for controlling flow through the second outlet to the mixing chamber; wherein the housing has a length dimension, a width dimension, and a thickness dimension, and the largest of these dimensions is no more than approximately 65 millimeters.

A fluid flow control system having a fluid inlet configured to be operatively coupled to a fluid source, a fluid outlet in fluid communication with the fluid inlet such that fluid may exit the system therethrough, a proximity sensor for detecting the position of an object within a region adjacent the sensor, and a flow control device configured to regulate fluid flow between the inlet and outlet in response to object detection by the sensor, wherein the flow control device varies the fluid flow proportional to the detected distance of an object from the sensor. A water flow control system for use in a shower environment is also provided, as well as a shower control system, methods for controlling water flow based on sensing of the presence and location of an object, and methods for reducing water consumption.

A water heater system includes a water heater and a thermal mixing valve. The water heater includes a tank and a cap that each define interior volumes. The interior volume of the tank includes a heating element is the location where fluid is heated, whereas the cap includes a volume within which the thermal mixing valve may be disposed. The thermal mixing valve pulls cool and warm water from the volume of the tank, and then discharges a mixed stream of fluid at a user desired temperature via an outlet.

A valve core connection structure of a valve assembly comprising: a body, two stop valve sets, two limitation structures, and two locking sleeves. The body includes a holder, a cold-water inflow connector, a hot-water inflow connector, a first outflow connector, a second outflow connector, a cold-water inflow seat, and a hot-water inflow seat. Each stop valve set includes a valve core, a limiting loop, a defining structure, and a locating structure. Each limitation structure is defined between a peripheral fence of each second accommodation cavity and the limiting loop so that the limiting loop is retained on the peripheral fence of each second accommodation cavity, thus limiting rotation of the limiting loop. Each locking sleeve is screwed on the cold-water inflow seat and the hot-water inflow seat so that the limiting loop and the valve core are limited in each second accommodation cavity.
