Abstract

L'invention porte sur une pompe à palettes à capacité variable, qui comprend une première chambre de commande entre un carter de pompe et une première partie d'un anneau de commande de pompe. La première partie de l'anneau de commande s'étend de façon circonférentielle de part et d'autre d'un axe de pivotement. Une seconde chambre de commande est formée entre le carter de pompe et une seconde partie de l'anneau de commande de pompe. Les première et seconde chambres de commande peuvent recevoir un fluide mis sous pression pour créer une force servant à déplacer l'anneau de commande de pompe pour réduire la capacité volumétrique de la pompe. Un ressort de rappel sollicite l'anneau de pompe vers une position de capacité volumétrique maximale.
