Abstract

La pompe comprend un corps mobile (22) en rotation dans un corps immobile (21), qui bascule entre deux positions de butée (28, 29) opposées, tout en opérant une commutation de jonction de conduits (32, 33, 34, 35) selon le sens de rotation, qui peut s’inverser, des roues dentées (25, 26) de cette pompe à engrenage. Le basculement s’opère simplement par la résultante des forces de pression du fluide entre l’admission et le refoulement. On obtient un sens de circulation invariable de l’huile vers un équipement à lubrifier (9), indépendamment d’inversions de sens de rotation de l’engrenage. Figure pour l’abrégé : Figure 4.
