Title (EN) REVERSIBLE VANE PUMP AND MOTOR
(FR) POMPE A PALETTES ET MOTEUR REVERSIBLES
Abstract:
(EN) A long-life, low maintenance, bi-directional vane-type water pump has a high degree of symmetry and operates with equal efficiency in either direction. The axial position of the drive shaft is controlled to permit improved lubrication by the pumping fluid of component parts on which the drive shaft is journaled.
(FR) L'invention concerne une pompe à eau à palettes, bidirectionnelle, longue durée, nécessitant peu d'entretien, et à haut degré de symétrie fonctionnant avec une efficacité égale dans les deux sens. La position axiale de l'arbre d'entraînement est commandée de manière que le fluide de pompage puisse assurer une lubrification améliorée des composants sur lesquels l'arbre d'entraînement est tourillonné.
