Title
(EN) FLOW CONTROL SYSTEM FOR PUMPING DEVICE
(FR) SYSTÈME DE COMMANDE D'ÉCOULEMENT POUR DISPOSITIF DE POMPAGE
Abstract
(EN) A pumping device (100) or a pump apparatus (200) including a flow control system (122, 220). The flow control system (122, 220) includes a non-return valve (124, 230) and an actuation mechanism (128, 242). The non-return valve (124, 230) have a closing member (126, 232) movable between an open position and a closed position to allow a unidirectional fluid flow and the actuation mechanism (128, 242) have an actuation element (130, 244) movable between an operative position and an inoperative position with respect to the closing member (126, 232). In the operative position, the actuation element (130, 244) applies a counteracting force (CF) to move the closing member (126, 232) to the open position and the actuation element (130, 244) is biased towards the operative position.
(FR) L'invention porte sur un dispositif de pompage (100) ou sur un appareil de pompage (200), lequel comprend un système de commande d'écoulement (122, 220). Le système de commande d'écoulement (122, 220) comprend un clapet de non-retour (124, 230) et un mécanisme d'actionnement (128, 242). Le clapet de non-retour (124, 230) a un élément de fermeture (126, 232) mobile entre une position ouverte et une position fermée de façon à permettre un écoulement de fluide unidirectionnel, et le mécanisme d'actionnement (128, 242) a un élément d'actionnement (130, 244) mobile entre une position fonctionnelle et une position non fonctionnelle par rapport à l'élément de fermeture (126, 232). Dans la position fonctionnelle, l'élément d'actionnement (130, 244) applique une force contraire (CF) pour déplacer l'élément de fermeture (126, 232) jusqu'à la position ouverte, et l'élément d'actionnement (130, 244) est vers la position fonctionnelle.
