A thermostatic valve includes a hollow body, two openings opening into the body and being hydraulically connected by a pass section, and a shut-off component arranged partially in the pass section and having a thermostatic actuator, a return component, a valve capable of opening the first opening when actuated by the thermostatic actuator and of closing the first opening when returned by the return component. The thermostatic actuator includes a cylinder containing an expansion material and a stem defining an axial direction. A relative movement between the cylinder and the stem along the axial direction occurs under the action of the expansion material. The stem bears at an ends against an abutment element, which is movable under the action of movement component in the direction of the cylinder to allow the opening of the first opening when the temperature of the expansion material is below the threshold temperature.

The invention concerns a thermostatic valve (1) comprising a closed hollow body (2), a first opening leading into the hollow body (2), referred to as the inlet opening (4), a second opening leading into the hollow body (2), referred to as the main outlet (5), a third opening, substantially perpendicular to the second opening, leading into the hollow body (2), referred to as the bypass outlet (7), and a seal (11) allowing the inlet opening (4) to be alternately separated from the main outlet (5) or the bypass outlet (7). The seal (11) comprises a thermostatic actuator (12) and a skirt (13) which is made of plastic material and has at least one window (19) suitable for being traversed by a fluid, the skirt (13) being capable of sliding in the hollow body (2), along an axis that substantially coincides with the axis of the thermostatic actuator (12), between a first position in which the skirt (13) seals the main outlet (5), such that the fluid flows between the inlet opening (4) and the bypass outlet (7), and a second position in which the skirt (13) leaves the main outlet (5) open and seals the bypass outlet (7), such that the fluid from the inlet opening (4) can pass through the window (19) and flow through the main outlet (5).

A water flow rate automatic control module, relating to the field of thermostatic shower fittings. The water flow rate automatic control module comprising a base, a valve body, a thermosensitive assembly, a diaphragm, wherein a temperature sensing part senses the temperature of passing cold water in real time; when the temperature of cold water is too low, the mixed water flow rate is slowed down, and more hot water is supplied to a thermostatic valve core assembly for mixing; when the temperature of cold water is too high, the mixed water flow rate is increased, and more cold water is supplied to the thermostatic valve core assembly for mixing. Therefore, the mixed water temperature range of the thermostatic valve core assembly can be ensured, and the problem of temperature adjustment failure or beyond the temperature difference caused by matching the thermostatic shower with a gas water heater is solved.

Thermal control systems that include variable conductivity metamaterial units are provided. The metamaterial unit a plurality of thermally conductive plates, a plurality of first bonds, each of which connects two adjoining thermally conductive plates, and a plurality of second bonds, each of which connects two adjoining thermally conductive plates. Also included is a load inducer constructed to cause the plurality of thermally conductive plates to move between a non-contact state, in which opposing surfaces of the plurality of thermally conductive plates are not in direct contact, to a contact state, in which the opposing surfaces of the plurality of thermally conductive are in at least partial direct contact, so as to change a thermal conductivity of the metamaterial unit from a first value to a second value. Through the ability to design the effective thermal conductivity as a function of temperature a passive thermal control capability is achieved by the introduction of thermal stability regions that will passively ensure thermal stability.

A valve includes a first inline compartment to attach to a first return line exiting a processing chamber and a second inline compartment to attach to a second return line entering a coolant source. A flow compartment is attached between the first inline compartment and the second inline compartment and through which a coolant is to return to the coolant source. A first inlet orifice and a second inlet orifice positioned between the first inline compartment and the flow compartment. A plunger has a tip to variably open and close the second inlet orifice. A shape memory alloy (SMA) spring is positioned on the plunger and attached to the tip, the SMA spring to variably increase or decrease a flow rate of the coolant through the second inlet orifice according to a temperature of the coolant.

A temperature-controlling water valve is provided. An adjusting assembly is assembled within the water valve and includes an adjusting member, a first elastic member, a blocking member and an abutting member. The first elastic member biases the abutting member, and the blocking member is fixed to the adjusting member to block the abutting member from detaching from a receiving hole of the adjusting member. A temperature-controlling assembly includes a valve member and a second elastic member biasing the valve member. Thermal expansion or contraction of a rod member of the valve member drives the valve member to move so that an overlapping area of the valve member and a first passageway of the water valve and an overlapping area of the valve member and a second passageway of the water valve change.

A thermostatic valve including a closed hollow body, a first opening and a second opening in the body, a stopper separating the first opening from the second opening, a thermostatic actuator capable of opening the stopper and a biasing member capable of closing the stopper, wherein the stopper includes a movable cage capable of sliding in relation to a fixed cage along an axis substantially coinciding with the axis of the thermostatic actuator, the movable cage or the fixed cage having at least one port, and the relative movement of the movable cage 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 is made of plastics.
