A high temperature protective valve and the use thereof in a shower head, wherein the high temperature protective valve includes a body, the body having a complete one-way waterway, and also a thermo-sensitive assembly and a pivot valve assembly. The thermo-sensitive assembly is fixed inside the body and has a memory alloy body which can be immersed in the waterway and extend and retract along the direction of the flow. The pivot valve assembly is also fixed inside the body downstream waterway of the thermo-sensitive assembly. The pivot valve assembly has a pivot valve plug which is controllable by the thermo-sensitive assembly so as to cut off the waterway. The high temperature protective valve of such a structure has a fast response and can achieve good protective effects at a high temperature.

The present invention provides an electronic plumbing fixture fitting, such as an electronic faucet. The electronic plumbing fixture fitting includes a wand hose and a hose bracket. The hose bracket is operable to connect to a mounting shank and to the wand hose. The hose bracket is operable to position the wand hose between a mixed water outlet of a flow module and an inlet of the mounting shank such that a portion of the wand hose extends in a loop between the hose bracket and the inlet of the mounting shank. When installed, the hose bracket is in direct contact with the wand hose between the mixed water outlet of the flow module and the inlet of the mounting shank.

A depressurisation valve for a cooling system including a main chamber having a main valve, a pilot line having a secondary valve and a blowdown line; the main valve being located to seal a path of the coolant system of the nuclear reactor. The main chamber is connected to the cooling circuit via the pilot line allowing coolant to enter the main chamber, and the blowdown line allows coolant to escape from the main chamber, the pilot line having a lower fluid resistance than the blowdown line. The pressure of coolant in the main chamber maintains the main valve in a closed position, and under elevated temperature and/or pressure conditions fluid is prevented from entering the main chamber via a closure of the secondary valve on the pilot line and reduce the pressure from the valve, moving it to its open position.

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.

Fuel recirculation methods, fuel supply circuits and fuel recirculation valves for selectively mixing hot return fuel from a diesel engine with fuel from a tank before providing it to back to the engine. In exemplary disclosed embodiments of fuel recirculation valves, the valves are configured to selectively mix the fuel in a controlled manner using a temperature sensitive actuator within the valve such that, when the temperature of the fuel reaches a certain point, the valve restricts flow pathways to reduce heated fuel being mixed with fuel from the fuel tank, and eventually closes to prevent any heated fuel from being mixed and overheating the fuel provided to a fuel filter, a fuel pump and the engine. Disclosed fuel circulation valves are separate from the fuel filter and are placed upstream of the filter.

There are provided a throttle mechanism and the like that are capable of easily changing a cross-sectional area of a flow path according to an operating state. The throttle mechanism in an embodiment is a throttle mechanism that controls a flow rate of a fluid flowing through a flow path, and is configured to make a cross-sectional area of the flow path change autonomously according to temperature.

A coolant control ball valve assembly comprises a housing that includes a housing chamber. The coolant control ball valve assembly further comprises a channel and a plurality of ports that extend from the housing chamber, and a valve element positioned in line with the channel and the plurality of ports. Additionally, the coolant control ball valve assembly comprises an actuator assembly in communication with the valve element. The actuator assembly includes an expansion element, and linear translation of the actuator assembly results in rotational translation of the valve element. Further, the coolant control ball valve comprises a flow diverter positioned adjacent the valve element. The flow diverter allows for coolant to reach a minimum velocity around the expansion element.

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. Yet other embodiments include one or more features that consider the special needs of a person temporarily blinded, and include those persons having disabilities.

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.
