This cartridge comprises a base (10), a fixed attached piece (20), a spool (30) for controlling the temperature of the mixture of the hot and cold fluids, and a thermostatic element making it possible to move the spool along an axis. The base simultaneously delimits an outlet orifice (16) for the mixture, an inlet orifice (14) for the cold fluid that supplies, via a first distribution channel (F4), cold fluid around the spool, a passage (F3), delimited axially between the spool and the base, and an inlet orifice (15) for the hot fluid that supplies, via a second channel (C4) for distribution hot fluid around the spool, a passage (C3) delimited axially between the spool and the attached piece. In order for the base to remain simple and cost-effective to produce, while still favoring the flow of high fluid flow rates through it, the invention proposes to close, axially toward the outlet orifice, the first distribution channel by means of the spool and the second distribution channel by means of the attached piece.

In some examples, a wireless controller is utilized within a wireless mesh network. The wireless controller includes a control module configured to manage at least one energy device via a pneumatic pressure line based on one or more parts of an energy profile; and a network interface module configured to transmit energy data to a management server and receive the one or more parts of the energy profile from the management server.

The invention relates to a thermostatic mixing valve with integrated flow diverter provided with a first coupling for a control lever for the flow rate adjustment and the flow diversion through a valve group that is housed between a base and a cylindrical body, and with a second coupling for a knob for the temperature adjustment through a thermostatic device, said valve including a member for the transmission of the flow rate adjustment and flow diversion control that directly connects the control lever to the valve group passing through the cylindrical body without moving it, the latter being also enclosed within an external casing secured to the base and achieving a watertight sealing with the base.

In a rotary handle for a thermostatically controlled valve, which is arranged on an actuator brought out of a valve housing, having a stop body, which acts together with a stop cam provided on the valve housing. It is provided that the stop body is movable in the rotation direction in such a way that by a relative movement between the stop body and the rotary handle, turning of the rotary handle by a rotation angle greater than 360° is made possible.

A bypass valve for thermally regulating a fluid flow in two directions by opening and closing a bypass fluid flow between the two directions. An example of application of such a bypass valve is for regulating the flow of engine coolant fluid between a vehicle engine and a heat-exchange system for cooling down the engine coolant. The bypass valve includes a housing inside which a first port, a second port, a bypass port and a barrier assembly are arranged. The barrier assembly is movable with respect to the bypass port, so that it can open or close the port depending on fluid temperature. In addition, the barrier assembly is arranged external to the first and second ports, so that it does not interfere with fluid passing through them. The bypass valve therefore provides substantially constant fluid pressure in the first and second ports, avoiding pressure drops associated with conventional bypass valves.

A heater is provided that includes at least one resistive heating element having a material with a non-monotonic resistivity vs. temperature profile and exhibiting a negative dR/dT characteristic over a predetermined operating temperature range along the profile. The heater can include a plurality of circuits disposed in a fluid path to heat fluid flow.

A device for tempering a sample located in a container for a flash point determination test and/or fire point determination test is provided, the device comprising: a temperature control block having a, in particular cylindrical, container receptacle for receiving the container; a cooling air guide body for delimiting a cooling air path in which the temperature control block is arranged; wherein the temperature control block has an outer surface with fins.
