Abstract

Un ensemble de pompe comprend un boîtier ou carter (2) muni d'une cavité (2C) dont la surface interne (2a) présente une section circulaire; une vanne ou une pluralité de vannes (3) logées dans la cavité du boîtier; et au moins un panneau d'extrémité (7) pour boîtier. Cet ensemble de pompe achemine un liquide selon mouvement rotatif depuis une lumière d'admission (22) du boîtier jusqu'à une lumière de refoulement (21) du même boîtier, lesdites lumières d'admission et de sortie étant séparées l'une de l'autre. Le centre de rotation de ladite vanne (3) est disposé excentrique par rapport au centre (2') de la dite surface interne (2a), ladite vanne (3) étant animée d'un mouvement alternatif par rapport à l'arbre (4) au niveau de son centre de rotation.
