Abstract

La présente publication comprend un corps de pompe muni d’une arrivée d’eau et d’une sortie d’eau. Un tube de jet et une turbine sont agencés dans le corps de pompe. Le liquide passe, dans l’ordre, à travers l’arrivée d’eau, le tube de jet, la turbine et la sortie d’eau. Au moins un canal d’accroissement de débit est agencé à la périphérie externe du tube de jet. Le canal d’accroissement de débit est agencé autour de l’extérieur du tube de jet. Le canal d’accroissement de débit communique avec l’arrivée d’eau et une arrivée de la turbine. Le liquide passant à travers le canal d’accroissement de débit est projeté vers la chambre de mise sous pression par la turbine. Le canal d’accroissement de débit est muni d’un noyau de soupape. Le mouvement du noyau de soupape dans le canal d’accroissement de débit engendre l’ouverture ou la fermeture du canal d’accroissement de débit. Figure à publier avec l’abrégé : Figure 1
