Abstract

L'invention concerne une pompe à liquide de refroidissement à entraînement mécanique présentant une capacité de refoulement pouvant être régulée pour un circuit de refoulement principal provenant d'une première sortie et pour un circuit de refoulement secondaire provenant d'une deuxième sortie de la pompe à liquide de refroidissement. La pompe présente entre autres un circuit de régulation hydraulique (5) dévié du liquide de refroidissement pourvu d'une pompe auxiliaire (6) côté entrée, d'une soupape proportionnelle (7) côté sortie et d'un tiroir de régulation (8) faisant office d'actionneur hydraulique destiné à limiter le débit du circuit de refoulement principal, une partie cylindrique du tiroir de régulation (8) pouvant coulisser axialement dans la chambre de pompe (10) aux fins de protection radiale de la roue à aubes (2) de la pompe, et ce au moyen d'une pression dans le circuit de régulation hydraulique (5) à l'encontre d'une force de rappel. La pompe à liquide de refroidissement se caractérise en particulier par le fait qu'une soupape (9) de régulation faisant office d'actionneur hydraulique destiné à limiter le débit du circuit de refoulement secondaire est reliée au circuit de régulation hydraulique (5), des actionnements du tiroir de régulation (8) et de la soupape (9) de régulation étant associés à des zones de pression respectives dans le circuit de régulation hydraulique (5).
