Abstract

Pompe à plateaux d'excentriques comportant des échelonnements successifs axiaux avec chaque fois un plateau fixe (stator 15) avec évidement central dans lequel se déplace excentriquement un plateau mobile (rotor 17), les groupes voisins de ces ensembles étant décalés les uns par rapport aux autres suivant un angle divisionnaire adapté à la largeur s des échelons et que les plateaux mobiles 17 sont calés sur un arbre excentrique 18 de façon que, pour chaque échelon, l'évidement du plateau fixe 15 constitue une courbe enveloppante pour la trajectoire du plateau rotatif 17, les plateaux fixes 15 d'échelons voisins étant orientés au moyen d'accouplements adéquats 26 exactement sous un deuxième angle divisionnaire de valeur moitié d'un premier angle divisionnaire formé entre les plateaux mobiles de même échelonnement.
