A system for collecting and accumulating excess water from one or more in-building sources and delivering it to one or more flushing toilet tanks and possibly also to one or more other in-building consumption devices, such as washing machines or utility faucets. The in-building sources may include any of condensate from an air conditioner, cool water in a hot water supply pipe emerging during initial flow, treated waste water and collected rain- or snow water. At the heart of the disclosed system is an accumulation tank of large capacity, having at least two inlets and at least one outlet. One of the inlets is connected to the main water supply system and includes a valve, configured to let fresh water flow into the main tank whenever the level of the water stored therein falls below a given height. Each outlet is connected to a conduit, conveying water from the accumulation tank to one or more toilet flushing tanks, as their only source, and possibly to other water consumption devices.

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.

A method adjusts a regulated temperature in a faucet that includes a spout, a faucet body, a hot water valve and a cold water valve. The method includes regulating a maximum water temperature of water provided to the spout using a thermostatic valve cartridge to add cold water that bypasses the cold water valve to the water provided to the spout as a function of water temperature inside the thermostatic valve cartridge. The thermostatic valve cartridge is affixed to the faucet body and external access to the thermostatic valve cartridge is inhibited by at least one element. The method also includes removing the at least one element to expose at least a portion of a thermostatic valve cartridge, and rotating a rotatable portion of the thermostatic valve cartridge to adjust the regulated maximum water temperature.

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.

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.

Compressor device that comprises a compressor element that is equipped with a compression chamber with at least one coolant inlet, and which furthermore comprises a gas outlet, a gas/coolant separation tank connected to it, and, a cooling circuit with a cooler that extends between the separation tank and the coolant inlet, and which is equipped with control means to adjust the temperature of the coolant flow supplied to the compressor element, whereby the aforementioned control means comprise a first and a second sub-controller, each with a different target parameter, whereby the control means also comprise switching means to place one of the two sub-controllers in an activated state and the other sub-controller in a deactivated state.

An electrically operable valve assembly for an electronic faucet includes a valve housing having an interior region for receiving a fluid, a solenoid valve, and a temperature sensor positioned outside the interior region. A heat transfer device extends between the temperature sensor and the interior region to transfer heat from fluid in the interior region to the temperature sensor. A controller is in communication with the temperature sensor and operative to control the solenoid valve.

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.

A fluid circuit includes a device, a cooler, and a valve. The valve includes a housing, a sealing member, a biasing device, and an actuator. The sealing member moves inside the housing between a first position and a second position. The actuator includes a smart material that is activated when the temperature of a fluid inside the housing exhibiting at least a first temperature, causing the sealing member to move to the second position. The smart material is deactivated when the fluid is a sufficient number of degrees less than the first temperature, causing the sealing member to move to the first position. The fluid flows from the housing to the device and then to the housing when the sealing member is in the first position. The fluid flows from the housing to the cooler and then to the device when the sealing member is in the second position.
