Abstract

Le boîtier (12) de cette vanne (10) délimite intérieurement une chambre (14) dans laquelle débouchent une première entrée (20) de fluide présentant une première température, une seconde entrée (22) de fluide présentant une seconde température, et des première (16) et seconde (18) sorties de fluide en libre communication avec respectivement les première et seconde entrées. Pour réguler la circulation du fluide à travers la vanne, des moyens thermostatiques de commande (24) sont prévus pour, mettre en communication, par la chambre (14), la première entrée (20) avec la seconde sortie (18) et la seconde entrée (22) avec la première sortie (16), uniquement lorsque soit la valeur de la première température est inférieure à une première valeur seuil prédéterminée, soit la valeur de la seconde température est supérieure à une seconde valeur seuil prédéterminée, strictement supérieure à la première valeur seuil.The housing (12) of this valve (10) internally delimits a chamber (14) into which a first fluid inlet (20) having a first temperature, a second fluid inlet (22) having a second temperature, and first (16) and second (18) fluid outlets in free communication with the first and second inputs, respectively. To regulate the circulation of the fluid through the valve, thermostatic control means (24) are provided for communicating, through the chamber (14), the first inlet (20) with the second outlet (18) and the second input (22) with the first output (16), only when either the value of the first temperature is lower than a first predetermined threshold value, or the value of the second temperature is greater than a second predetermined threshold value, strictly greater than the first threshold value.

Application à un circuit de refroidissement d'un moteur thermique et d'un système de re-circulation des gaz d'échappement provenant de ce moteur.
