A thermostat device for a motor vehicle cooling system includes a valve, a heat-sensitive component to induce opening of the valve when the temperature of the sensitive component exceeds a temperature threshold, and a heating module controlled by the sensitive component. The heating module delivers at most a maximum heating power. The heating module includes a regulating module to determine a gross useful voltage based on a measured temperature and of a temperature setpoint, and a correcting module including an electrical resistor connected to an electrode. The correcting module controls the heating module either to limit the heating power delivered by the heating module to a heating power strictly lower than the maximum heating power and sufficient to induce complete opening of the valve, or so that the heating module delivers non-zero heating power that is not sufficient to induce opening of the valve.

A heating cartridge with a thermally conductive tube which can be immersed in a thermodilatable material of a thermostatic member. Having a cylindrical body extending axially via a flare; internal electric heating; a base of a plastic material, secured to the tube by overmolding the flare, supporting an electrical connection between the heater and an external current source, and is suitable to be received in a casing of the valve housing. A seal is attached to the base and has a first portion pressed radially against the housing in the casing so as to seal the interior of the casing. In order to improve the sealing of said cartridge, the seal also includes a second portion, which is separate from the first portion and which is pressed radially against the cylindrical body of the tube to seal the overmolding interface between the flare of the tube and the base.

The present invention relates generally to an electronic thermostat. More particularly, the present invention relates to an electronic thermostat configured to operate a valve by using expansion pressure of a thermally expandable material as a heater generates heat, wherein foreign substances are prevented from being accumulated in a guide cap, thus preventing malfunction of the valve from occurring. The electronic thermostat configured to control flow of a coolant by using a piston reciprocating in response to expansion and contraction of a thermally expandable material includes: a casing; a heater; a guide; the piston; a sealing member; a guide cap; and a valve, wherein the guide cap has a discharge hole formed at a lower end thereof.

An engine cooling system for increasing and controlling a wall temperature of a cylinder head is provided. The cooling system includes a radiator passage that passes through a radiator, a radiator-bypass passage that bypasses the radiator, a first fluid temperature sensor that acquires a fluid temperature of an engine coolant flowing through a bore passage for cooling a cylinder, a second fluid temperature sensor that acquires the fluid temperature of the engine coolant flowing through a head passage for cooling a cylinder head, a thermostat valve arranged in the radiator passage, a flow rate regulator valve arranged in the radiator-bypass passage, and an electronic control unit (ECU). While controlling the thermostat valve on the basis of a detection result of the first fluid temperature sensor, the ECU controls the flow rate regulator valve on the basis of a detection result of the second fluid temperature sensor.
