Abstract

L'invention concerne une pompe à engrenages télescopiques comprenant un écrou, une rondelle Belleville, une plaque d'usure, un boîtier d'étanchéité, un ressort étanche, un engrenage droit comprenant un lobe d'usure, une bague d'étanchéité et un chemin de drainage de carter, un arbre, une couronne comprenant un lobe d'usure, une bague d'étanchéité, ainsi qu'un chemin de drainage de carter, un joint d'étanchéité, un ensemble écrou comprenant une rondelle Belleville et un écrou, et une plaque de pression. L'ensemble assure une pression à un fluide afin de maintenir une étanchéité dans un ensemble pompe/moteur télescopique au cours du fonctionnement. Le lobe d'usure réduit l'usure tout en maintenant une pression du fluide.
