Abstract

SYSTEME D’INJECTION HYDRAULIQUE A CAME 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). Figure pour l’abrégé : Fig. 1HYDRAULIC CAM INJECTION SYSTEM The hydraulic cam injection system (100) comprises an injection valve (50) housed in a tubular injection nozzle (54), a space being left between a valve stem (51 ) of said valve (50) and the inner surface of the tubular injection nozzle (54) to allow an injectable fluid (58) to flow from pressurizing means (10) while a receiving piston (62) integral of said valve (50) receives on the one hand, the pressure of the injectable fluid (58) to maintain said valve (50) closed, and on the other hand, the pressure of a hydraulic fluid (60) to open said valve ( 50), an injection cam (67) capable of moving said receiver piston (62) via a transmitter piston (69) and said hydraulic fluid (60).
