A flow control device can include water in a chamber, the chamber having a variable volume, a flow restricting member which displaces in response to a change in the chamber volume, and a biasing device which influences a pressure in the chamber. A method of controlling flow of steam in a well can include providing a flow control device which varies a resistance to flow in the well, the flow control device including a chamber having a variable volume, water disposed in the chamber, and a biasing device. The biasing device influences the chamber volume. Another flow control device can include water in a chamber, the chamber having a variable volume, a flow restricting member which displaces in response to a change in the chamber volume, and a biasing device which reduces a boiling point of the water in the chamber.

An electronic faucet includes a spout, a fluid supply conduit supported by the spout, and a valve assembly including an electrically operable valve. A controller is coupled to the valve assembly and includes a processor operative to control the electrically operable valve to control fluid flow through the fluid supply conduit. The controller includes a port in communication with the processor, the port being releasably coupled to electronics of a secondary device.

Apparatus and method for providing tempered water to an emergency wash system. Various embodiments include simple, reliable, low-cost flow regulators to reliably provide adequate emergency wash flows.

A solenoid device including pressure altering means for altering an output pressure of the solenoid device; and an actuator for providing an actuating signal to said pressure altering means; wherein the solenoid device further includes a sensor arranged to sense a control value of the solenoid device, and a controller which receives a request and is arranged to control delivery of power to the actuator with feedback from the sensor until the control value meets the request.

A heat exchanger is configured to adjust a flow restriction of flow passages through the heat exchanger in response to changes in temperature of elements that define at least a portion of the flow passages. The elements include a first material having a first coefficient of thermal expansion, and a second material having a second coefficient of thermal expansion that is different from the first coefficient of thermal expansion.

The water diversion assembly of the present invention herein diverts and preserves the water supply when water supply is currently below the threshold temperature. The present invention relates to a water diversion assembly having a hot water inlet connected to a hot water supply and a cold water inlet connected to a cold water supply. An appliance outlet, for use by the user of an appliance, is configured to connect and deliver a water mix at an outlet temperature. The appliance outlet is in fluid communication with the hot water inlet, the cold water inlet, and a water collection outlet. Within the water diversion assembly, a thermostatic diversion valve having a hot water threshold temperature setting and arranged such that water from the hot water supply via the hot water inlet is delivered to the water collection outlet until the hot water threshold temperature is reached and then thermostatically diverted to a thermostatic mixing valve.

A multistage automated thermally actuated valve utilizing a thermally expansive substance to substantially close the valve at a first temperature and a spring to open the valve at a second, lower temperature. A multistage automated valve comprising a first thermal assembly to balance fluid flow at a first temperature and a second thermal assembly to balance fluid flow at a second temperature in order to balance fluid flow in a system operated at a first temperature as well as at a second temperature. A method of utilizing an automated thermally actuated valve to balance and manage hot water supply in a piping system.

A valve device for a fuel filter module has a first fluid channel through which fuel flows only in recirculation mode of the fuel filter module and a second fluid channel through which fuel flows only outside of the recirculation mode. The first fluid channel extends inside the second fluid channel. The first and second fluid channels are coaxial to each other. A fuel filter module switchable into recirculation mode and out of recirculation mode is provided with a control valve that has a valve bore and a valve device arranged in the valve bore, wherein the valve device has a first fluid channel through which fuel flows only in recirculation mode and a second fluid channel through which fuel flows only outside of the recirculation mode. The first fluid channel extends inside the second fluid channel, and the first and second fluid channels are coaxial to each other.
