Abstract
(EN) A peristaltic pump that reduces electrical current flowing through a pumping tube segment includes a central rotor mounted on a central rotation axis, a shoe with a curved surface facing toward the central rotor, multiple rollers mounted along the circumference of the central rotor and the pumping tube segment positioned between the curved surface and the central rotor. Each roller of the plurality of rollers is a member of a roller group, each roller group includes at least two rollers, rollers in a particular roller group are physically located closer to each other than to rollers in other roller groups, and at least two rollers pinch a portion of the pumping tube segment against the curved surface through a full rotation of the central rotor.
(FR) Une pompe péristaltique qui réduit le courant électrique circulant à travers un segment de tube de pompage comprend un rotor central monté sur un axe de rotation central, un sabot ayant une surface incurvée faisant face au rotor central, de multiples rouleaux montés le long de la circonférence du rotor central et du segment de tube de pompage positionné entre la surface incurvée et le rotor central. Chaque rouleau de la pluralité de rouleaux constitue un élément d'un groupe de rouleaux, chaque groupe de rouleaux comprend au moins deux rouleaux, des rouleaux dans un groupe de rouleaux particulier sont physiquement situés plus près les uns des autres que des rouleaux dans d'autres groupes de rouleaux, et au moins deux rouleaux pinçant une partie du segment de tube de pompage contre la surface incurvée par l'intermédiaire d'une rotation complète du rotor central.
