The present invention relates to a freeze prevention valve capable of controlling a discharge flow rate according to a temperature. More particularly, the present invention relates to a freeze prevention valve capable of controlling a discharge flow rate according to a temperature, wherein the valve is to prevent freezing of a pipe by allowing a working fluid such as water flowing along various pipes including water pipes, faucets, and water meters to continuously flow without freezing at a temperature below a freezing point, and a shape memory elastic body which is a configuration of the valve can control a flow rate of the working fluid flowing out of the valve by proportionally changing a yield stress by a phase change according to a temperature of the working fluid instead of performing a simple opening/closing operation.

Fluid supply assemblies for fluid systems are provided, including faucet assemblies (e.g., electrically or mechanically actuated faucet assemblies) having an integrated anti-scald device and having an integrated temperature mixing valve. An exemplary faucet assembly includes an integrated temperature mixing valve, and/or an integrated anti-scald device configured to stop the inlet flow of hot water in the event the mixed outlet water temperature exceeds a user-selected set point. The faucet assemblies can prevent scalding as defined by ASSE 1070.

A thermostatic integrated faucet includes a valve assembly having an upper valve body and a lower valve body defining a mixing chamber therein, the mixing chamber configured to receive hot water through a hot water inlet and cold water through a cold water inlet. The thermostatic integrated faucet further includes a diaphragm assembly fluidly coupled to the mixing chamber, a sensor operatively coupled to the diaphragm assembly, a thermostatic unit disposed within the mixing chamber of the valve assembly, and a cam shaft coupled to the thermostatic unit. The thermostatic unit is configured to control a water temperature within the valve assembly and the cam shaft configured to control a range of the water temperature within the valve assembly. In various embodiments, the thermostatic unit includes a wax actuator configured to engage with the cam shaft and a mixing shuttle coupled to the wax actuator.

A thermostatic valve comprises a closed hollow body (1), a first opening (2) and a second opening (3) in the body (1), a stopper separating the first opening (2) from the second opening (3), a thermostatic actuator (4) capable of opening the stopper and restoring means (5) capable of closing the stopper, the valve being characterised in that the stopper comprises a movable cage (7, 70) capable of sliding in relation to a fixed cage (6, 60) along an axis substantially coinciding with the axis of the thermostatic actuator (4), the movable cage (7, 70) or the fixed cage (6, 60) having at least one port (8, 80), and the relative movement of the movable cage (7, 70) in relation to the fixed cage allowing the at least one port (8, 80) to be selectively closed or opened, and in that the movable cage (7, 70) is made of plastics.

A hydraulic control system includes a primary sump and an auxiliary sump. When the transmission fluid is warm, fluid remains in the auxiliary sump reducing the volume of oil in circulation throughout the transmission to reduce parasitic losses. An oil control valve is designed to block flow of oil from the auxiliary sump to the primary sump when the fluid is warm and to allow flow when the fluid is cold. The oil control valve also responds to transmission line pressure. At moderate temperatures, fluid is held in the auxiliary sump when the engine is running but drains back to the primary sump when the engine is off.

A passive flow modulation device according to an embodiment includes: a pressure sensitive main valve controlling a flow of a cooling fluid from a first area to a second area through an orifice; and a temperature sensitive pilot valve coupled to the pressure sensitive main valve, the temperature sensitive pilot valve configured to open at a predetermined temperature in the first area, causing a pressurization of the pressure sensitive main valve, wherein the pressurization of the pressure sensitive main valve actuates the pressure sensitive main valve to an open position, allowing the cooling fluid to flow from the first area to the second area through the orifice.

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.

An excess flow and thermal valve assembly includes a valve housing, a valve carried in the housing and displaceable during excess flow conditions to reduce flow of fluid through the assembly, and an intumescent or intumescent material carried in the valve housing and expandable during excess temperature conditions to reduce flow of fluid through the assembly.
