Claims (9)

  1. Pompe à liquide de refroidissement pour un moteur à combustion interne comportant
    un arbre d'entrainement (18),
    une roue de pompe de liquide de refroidissement (20) disposée de manière fixe, au moins de manière fixe en rotation, sur l'arbre d'entrainement (18) et par laquelle le liquide de refroidissement peut être transporté,
    un coulisseau de réglage (58) ajustable, par lequel une section transversale d'écoulement d'un espace annulaire (62) entre une sortie (64) de la roue de pompe de liquide de refroidissement (20) et le canal de transport environnant (12) peut être réglée, le coulisseau de réglage (58) comportant une paroi périphérique cylindrique creuse extérieure (60), sur le côté radial extérieur de laquelle une rainure radiale (74) est formée dans laquelle une bague d'étanchéité (76) est disposée,
    caractérisée en ce que
    le coulisseau de réglage (58) présente une paroi périphérique cylindrique creuse intérieure (84), sur le côté radial intérieur de laquelle est formée une rainure radiale (86) dans laquelle est disposée une bague d'étanchéité (88), les deux parois périphériques (60, 84) étant reliées l'une à l'autre via un fond (80), le fond (80) séparant une première chambre de pression (92) d'une deuxième chambre de pression (94), de sorte que le coulisseau de réglage (58) peut être déplacé en fonction d'une différence de pression entre les deux chambres de pression (92, 94).
  2. Pompe à liquide de refroidissement pour un moteur à combustion interne selon la revendication 1, caractérisée en ce que les bagues d'étanchéité (76, 88) sont en PTFE (polytétrafluoroéthylène).
  3. Pompe à liquide de refroidissement pour un moteur à combustion interne selon l'une des revendications 1 ou 2, caractérisée en ce que les bagues d'étanchéité (76, 88) présentent chacune une fente (96, 98).
  4. Pompe à liquide de refroidissement pour un moteur à combustion interne selon la revendication 3, caractérisée en ce que la fente (96, 98) s'étend inclinée par rapport à l'axe central de la bague d'étanchéité (76, 88) respective.
  5. Pompe à liquide de refroidissement pour un moteur à combustion interne selon l'une quelconque des revendications précédentes, caractérisée en ce que la bague d'étanchéité (88) disposée sur le côté intérieur de la paroi périphérique (84) cylindrique creuse intérieure coulisse sur une surface extérieure (89) usinée d'une section cylindrique (90) d'une première partie de carter (26) de la pompe de refroidissement.
  6. Pompe à liquide de refroidissement pour un moteur à combustion interne selon l'une quelconque des revendications précédentes, caractérisée en ce que la bague d'étanchéité (76) disposée sur le côté extérieur de la paroi périphérique (60) cylindrique creuse externe coulisse sur une surface interne (78) usinée d'une saillie annulaire s'étendant axialement (52) d'une deuxième partie de carter (38) de la pompe de refroidissement.
  7. Pompe de refroidissement pour un moteur à combustion interne selon la revendication 6, caractérisée en ce que la paroi circonférentielle (60) cylindrique creuse extérieure présente un épaulement (66), à partir duquel la paroi circonférentielle (60) cylindrique creuse extérieure s'étend avec une circonférence externe agrandie vers la roue de pompe de liquide de refroidissement (22), le diamètre externe de cette section (68) ayant un diamètre agrandi essentiellement correspondant au diamètre extérieur de la saillie (52) annulaire s'étendant axialement de la deuxième partie de carter (38).
  8. Pompe à liquide de refroidissement pour moteur à combustion interne selon la revendication 7, caractérisé en ce que l'épaulement (66) repose axialement contre une extrémité de la saillie annulaire (52) de la deuxième partie de carter (26) en position complètement rétractée du coulisseau de réglage (58).
  9. Pompe à liquide de refroidissement pour moteur à combustion interne selon l'une quelconque des revendications précédentes, caractérisé en ce que les deux chambres de pression (92, 94) sont scellées de l'autre chambre de pression (92, 94) par les deux bagues d'étanchéité (76, 88).
