Abstract

Ce moteur hydraulique comprend un cylindre étagé 2 et un piston étagé 17 dont la partie avant 18 forme une pompe avec la portion 13 du cylindre et deux clapets respectivement d'aspiration et de refoulement 8 et 9. Le moteur est alimenté en eau sous pression par une entrée 99. Cette eau est transmise aux deux faces du piston 17 situées dans les alésages il et 12 du cylindre directement ou à travers des lumières et passages formés dans la paroi du piston et dans un manchon en deux pièces contenu dans la cavité de la tête de ce piston. Un tiroir coulisse dans ce manchon et traverse le chapeau 1 du cylindre. Ses mouvements sont limités par des butées et des épaulements et commandés par la pression. Dans ses mouvements, le tiroir modifie tantôt dans un sens et tantôt dans l'autre, les aires des surfaces du piston exposées à la pression régnant dans l'alésage 12 et à celle régnant dans l'alesage Il pour commander les mouvements du piston. Ce moteur est applicable notamment à l'injection de doses d'engrais liquide dans les canalisations d'irrigation.
