Abstract

L'invention concerne une pompe de liquide de refroidissement à régulation entraînée par une poulie à courroie, destinée à un moteur à combustion interne et se présentant sous la forme d'une pompe axiale à régulation. L'invention a pour objet de développer une pompe de liquide de refroidissement à régulation entraînée par une poulie à courroie, se présentant sous la forme d'une pompe axiale à régulation et destinée à un moteur à combustion interne, qui permette une commande active du volume de liquide de refroidissement transporté pour d'une part assurer un chauffage optimal du moteur grâce au « zéro fuite » et d'autre part agir avec précision sur la température du moteur en fonctionnement permanent après chauffage du moteur de telle manière qu'à la fois l'émission de substances polluantes, les pertes par frottement et la consommation de carburant puissent être considérablement réduites sur la totalité de la plage de fonctionnement du moteur. La nouvelle conception a pour objet de transmettre un couple élevé pour un encombrement minimum, de se distinguer par une réalisation très compacte, simplifiée en termes de technique de fabrication et de montage, peu coûteuse et robuste, ainsi que d'éviter les phénomènes de cavitation et les turbulences du flux volumique transporté et d'assurer une sécurité de fonctionnement et une fiabilité élevées sur une durée de vie prolongée même si le liquide de refroidissement est chargé en polluants. La pompe de liquide de refroidissement à régulation selon l'invention est notamment caractérisée en ce qu'une roue directrice (8) est disposée de manière solidaire en rotation dans le carter de pompe (1), un cône de guidage d'évacuation (14) présentant une nervure annulaire (15) étant placé sur cette roue dans la direction de l'orifice de sortie d'écoulement (3). Un espace de travail de coulisse (16) dans lequel pénètre le cône de guidage d'évacuation (14) de la roue directrice (8) est ménagé dans le carter de pompe (1). Dans cet espace de travail (16), une coulisse axiale (22) est disposée de manière à pouvoir coulisser linéairement et présente un profil de guidage d'évacuation (23), un orifice d'évacuation (24) ainsi qu'une rainure annulaire (25) assurant l'étanchéité en interaction avec la nervure annulaire (15).
