Abstract

Dispositif de régulation de température pour système de refroidissement, notamment d'un moteur à combustion interne de véhicule. Le système de ventilation peut fonctionner à deux régimes différents, à savoir un régime moyen lorsque la température en un premier point du système de refroidissement dépasse un premier seuil déterminé, et un régime supérieur, éventuellement maximal, lorsque la température en un second point du système de refroidissement dépasse un second seuil déterminé, supérieur au premier. Un organe de contrôle du débit du fluide de refroidissement, sensible à la température en un troisième point du système de refroidissement, est en outre prévu pour autoriser un faible débit dudit fluide ou un débit nominal, selon que la température en ce troisième point est inférieure ou supérieure à un troisième seuil. Principales applications : véhicules automobiles.Temperature control device for a cooling system, in particular of a vehicle internal combustion engine. The ventilation system can operate at two different speeds, namely an average speed when the temperature at a first point of the cooling system exceeds a first determined threshold, and a higher speed, possibly maximum, when the temperature at a second point of the system cooling exceeds a second determined threshold, greater than the first. A cooling fluid flow control member, sensitive to the temperature at a third point of the cooling system, is also provided to allow a low flow rate of said fluid or a nominal flow rate, depending on whether the temperature at this third point is lower. or greater than a third threshold. Main applications: motor vehicles.
