Abstract

L'invention concerne un réservoir d'eau d'appoint pour un système de refroidissement moteur, qui comporte un carter (200) avec une cavité (100). Le carter (200) est équipé d'un orifice d'alimentation en eau (31), d'une sortie d'eau (32), d'une entrée de gaz (201) et d'une sortie de gaz (202). L'orifice d'alimentation en eau (31) et la sortie d'eau (32) sont en communication respective avec la cavité (100). L'entrée de gaz (201) communique avec la sortie de gaz (202) par l'intermédiaire d'une conduite d'échappement. La conduite d'échappement ne communique pas avec la cavité (100). Le système de refroidissement moteur comprend le réservoir d'eau d'appoint et la conduite d'échappement séparés l'un de l'autre, de sorte que l'on peut empêcher le gaz provenant du moteur et d'un radiateur d'entrer dans le réservoir d'eau d'appoint et de se mélanger avec le liquide de refroidissement dans le réservoir d'eau d'appoint.
