Abstract
Le système d'injection hydraulique à came (100) comprend une soupape d'injection (50) logée dans une buse d'injection tubulaire (54), un espace étant laissé entre une queue de soupape (51) de ladite soupape (50) et la surface interne de la buse d'injection tubulaire (54) pour laisser circuler un fluide injectable (58) provenant de moyens de mise en pression (10) tandis qu'un piston récepteur (62) solidaire de ladite soupape (50) reçoit d'une part, la pression du fluide injectable (58) pour maintenir ladite soupape (50) fermée, et d'autre part, la pression d'un fluide hydraulique (60) pour ouvrir ladite soupape (50), une came d'injection (67) pouvant mettre en mouvement ledit piston récepteur (62) via un piston émetteur (69) et ledit fluide hydraulique (60).
