Abstract

Une pompe à capacité variable hydraulique conçue comme pompe à roue dentée intérieure, dans laquelle les dents de la roue extérieure (1) et de la roue intérieure (5) sont engagées les unes avec les autres entre les points d'intersection des cercles de tête de la denture. Ainsi des cellules de denture sont créées dans la région de sortie. Les cellules de la denture débouchent dans un canal de sortie commun à toutes, par des canaux de sortie (48) qui sont disposés à une certaine distance de la denture et qui sont fermés à chaque fois par une soupape de retenue. L'entrée est reliée au réservoir par deux ou trois canaux, dont le premier est équipé d'un papillon fixe (37), le deuxième est commandé par une soupape de commande de la pression (39) agissant en fonction de la pression régnant dans le chambre de compression (51) et le troisième est commandé par une soupape électromagnétique (59) agissant en fonction d'autres paramètres de fonctionnement.
