- This device comprises a main duct (2) which circulates the cooling liquid in the enclosure of the crankcase block and / or the cylinder head of the engine (1).
- the main duct (2) To this main duct (2) is associated a secondary duct (3) which recovers a portion of the flow of the main duct (2) to divert it out of the engine cooling chamber (1).
- the branching of the secondary duct (3) on the main duct (2) is effected upstream of the engine inlet of the coolant and downstream of a supply pump (5) so that the two ducts (2, 3) are fed by the same pump (5) while allowing a supply of the secondary conduit (3) with coolant which has not yet achieved heat exchange with an element to be cooled.
- the main duct (2) At the motor output, the main duct (2) comprises a two-way valve (4) which reversibly suspends the flow of cooling liquid in the main duct (2).
- this valve (4) avoids the positioning of a component at the interface between the pump (5) and the motor (1) to be cooled.
- closing the valve (4) makes it possible to stop the flow of the cooling liquid in the main duct (2). ) while maintaining a continuous flow in the secondary conduit (3).

- the thermal control device of the invention aims to be integrated in a cooling circuit of an engine (1) but also of one or more consumers (6) and / or accessories (11,
- the cooling circuit which integrates the device of the invention has a first cooling loop (7) which notably comprises the pump (5) and the main duct (2) which contributes to the cooling of the engine (1) and at least an accessory, for example a heater (11), cooled by the circuit of the first cooling loop (7).
- the only constraint in the positioning of the heater is to be placed on the main loop (7).
- the latter must, in fact, be fed with coolant having passed through the engine when the thermostat (4) is open.
- the flow of coolant flow in the first cooling loop (7) is dependent on the opening and the closing of the two-way valve (4) which makes it possible to stop the cooling of the engine (1) while stagnating the cooling liquid in the chamber of the crankcase block and / or the cylinder head.

- the thermostatic two-way valve (10) makes it possible to manage the circulation in the third loop (9) of the circuit as a function of the temperature of the circulating coolant.
- the thermostatic valve may, for example, incorporate a wax mixture which gradually becomes liquid when the temperature of the liquid, at which the thermostatic valve is immersed, increases. By liquefying, the wax mixture gradually expands to occupy a larger volume which then causes the movement of a valve or piston of the valve.
- the junction of the third loop (9) with the first loop (7) which is performed at the loop return, upstream of the supply pump (5) is the positioning point of the a double-acting thermostatic valve (14).

- the circulation of the coolant is kept constant through the supply pump (5) and the short-circuiting of the cooling of the engine (1) by the secondary conduit (3).
- the two-way valve (4) is open, the circulation of the coolant takes place in the first loop (7) and the second loop (8).
- the main pipe (2) of the device is then fed and the motor (1) is cooled by the cooling liquid in displacement.
