Abstract

Ce mécanisme de réglage de l'injection pour moteur Diesel comprend un piston 64 commandé directement par un arbre à cames 17 et un piston 66 qui attaque le plongeur 51 de l'injecteur. Une source 91 de fluide de réglage(huile de lubrification ou combustible) dont la pression de refoulement est fonction du régime et de la charge du moteur, débite dans une chambre forma entre les deux pistons et la quantité introduite à chaque cycle est fonction de la pression. Cette introduction est interrompue lorsque la pression est équilibrée par un ressort 71. Le volume de fluide forme une bielle hydraulique dont la longueur est fonction du régime et de la charge du moteur et qui commence ainsi plus ou moins tard à transmettre le mouvement de la came au plongeur. Un clapet permet au fluide de s'échapper en partie après la fin de l'injection.This injection adjustment mechanism for a diesel engine comprises a piston 64 controlled directly by a camshaft 17 and a piston 66 which drives the plunger 51 of the injector. A source 91 of adjusting fluid (lubricating oil or fuel), the discharge pressure of which is a function of the speed and the load of the engine, flows into a chamber formed between the two pistons and the quantity introduced at each cycle is a function of the pressure. This introduction is interrupted when the pressure is balanced by a spring 71. The volume of fluid forms a hydraulic connecting rod, the length of which depends on the speed and the load of the engine and which thus begins more or less late to transmit the movement of the cam. to the diver. A valve allows the fluid to partially escape after the end of the injection.
