Abstract

L’invention concerne un dispositif d’alimentation en pression d’un fluide dans lequel les tuyauteries de couverture de sortie (38, 38) de pompes de soupape à pulsation (P1, P2) sont couplées d’une seule pièce, les tiges de piston de ces pompes de soupape à pulsation sont couplées à une paire de bras de manivelle entraînés, respectivement, par une paire de coulisseaux guidés par un moyen de guidage, et les bras de manivelle entraînés sont couplés à un vilebrequin (10) présentant des bras de manivelle d’entraînement (11, 11A) se projetant suivant un angle prédéterminé dans la direction en rotation. Lorsque le vilebrequin est entraîné en rotation par la force d’entraînement d’un moteur d’entraînement, le piston (26) de l’autre pompe de soupape à pulsation (P2) démarre dans une position différente de la position de démarrage du piston (26) d’une pompe de soupape à pulsation (P1) et le fluide alimenté en pression par ces pompes de soupape à pulsation (P1, P2) circule à travers la tuyauterie de liaison côté aval (5) sans pulser. En conséquence, il est possible d’obtenir une « forme d’onde composite sans pulsation » et de réaliser facilement le nettoyage, le remplacement et la réparation d’éléments de soupape de retenue.
