Claims (5)

  1. Pompe de refroidissement construite selon le principe d'une pompe de refroidissement à entraînement mécanique pour moteurs à combustion avec un carter de pompe (2) avec une ouverture d'admission de courant (3) et une ouverture de sortie de courant (4), un arbre de pompe (6) disposé dans/sur le carter de pompe (2) de manière rotative au moyen d'un palier de pompe (5), un joint d'arbre de pompe (8) disposé du côté de l'entraînement à côté de l'ouverture d'admission de courant (3) dans une garniture (7), dans le carter de pompe (2) entre celui-ci et l'arbre de pompe (6), avec une roue directrice (9) équipée de pales directrice (10) fixe quant à la rotation et disposée dans le carter de pompe (2), dans laquelle roue directrice (9) se trouve un logement de palier (11) dans lequel est disposé un palier glissant (12), dans lequel est disposé l'arbre de pompe (6) avec son extrémité d'arbre de pompe située à l'opposé du côté d'entraînement, une roue (14) avec pales (15) étant disposée de manière fixe quant à la rotation sur l'arbre de pompe (6), au voisinage de la roue directrice (9) avec le palier glissant (12) en direction de l'ouverture d'admission de courant (3) autour d'une fente annulaire (13), et que l'ouverture d'admission de courant (3) est disposée latéralement par rapport à l'axe central d'arbre de pompe (6), de telle manière que l'admission de courant s'effectue en biais par rapport à l'axe de rotation de la roue (14), caractérisée par le fait
    - que la roue (14) est une roue à ailettes semi-axiale avec des pales (15) courbées de manière tridimensionnelle, et
    - que la roue directrice (9) fixe quant à la rotation dans le carter de pompe (2) possède un cône directeur (16) interne effilé en direction du courant et un chapeau directeur (17) externe de forme conique à une certaine distance du cône directeur (16), et
    - que le cône directeur (16) et le chapeau directeur (17), espacés l'un de l'autre de manière symétrique, sont reliés au moyen de pales directrices (10) courbées de manière tridimensionnelle, et
    - que la roue (14) est espacée de la roue directrice (9) par une fente annulaire (13) minimale en forme de fente d'étanchéité, la roue (14) étant espacée de manière minimale sur le côté frontal du bord extérieur voisin du cône directeur (16) comme également du bord extérieur voisin du chapeau directeur (17) par une fente annulaire (13) en forme de fente d'étanchéité, et
    - qu'une chambre d'amission (19) d'un diamètre intérieur (D) est disposée dans le carter de pompe (2) de manière symétrique en rotation par rapport à l'arbre de pompe (6) et placée immédiatement devant la roue (14), la longueur de chambre (L) se trouvant dans un intervalle de 0,7 à 1,5 fois le diamètre intérieur (D).
  2. Pompe de refroidissement selon l'exigence 1 caractérisée par le fait qu'une languette directrice (18) est disposée sur l'extrémité libre du chapeau directeur (17).
  3. Pompe de refroidissement selon l'exigence 1 ou l'exigence 2 caractérisée par le fait que, dans la zone d'ouverture de sortie de courant (4) sur le carter de pompe (2), une bride de sortie de liquide de refroidissement (20) est disposée.
  4. Pompe de refroidissement selon une ou plusieurs des exigences 1 à 3 caractérisée par le fait que la pompe de refroidissement entraînée mécaniquement est mise en rotation par une poulie à courroie (1), une roue dentée ou un arbre d'emboîtement.
  5. Pompe de refroidissement selon une ou plusieurs des exigences 1 à 4 caractérisée par le fait que la roue (14) est une roue de type Francis ou une roue à ailettes diagonale avec des pales (15) courbées de manière tridimensionnelle.
