Abstract[English]
A rocker arm assembly is operable in a drive mode and a cylinder decompression mode. The rocker arm assembly includes a rocker arm (110) pivotally mounted to a rocker shaft (120), and a decompression assembly pivotally mounted to a lever shaft (320) of the rocker arm. The rocker arm includes a valve end (150) configured to operatively engage one or more gas exchange valves (300) of a cylinder, and a cam end (200) configured to receive motion from a main cam (230). The decompression assembly includes a decompression lever (310) configured to provide an optimized decompression lift profile associated with the transitional states of engine operation.[French]
L'invention concerne un ensemble culbuteur qui peut fonctionner dans un mode d'entraînement et dans un mode de décompression de cylindre. L'ensemble culbuteur comprend un culbuteur (110) monté de manière pivotante sur un arbre de culbuteur (120), et un ensemble de décompression monté pivotant sur un arbre de levier (320) du culbuteur. Le culbuteur comprend une extrémité de soupape (150) conçue pour venir en prise fonctionnelle avec une ou plusieurs soupapes d'échange de gaz (300) d'un cylindre, et une extrémité de came (200) conçue pour recevoir un mouvement d'une came principale (230). L'ensemble de décompression comprend un levier de décompression (310) configuré pour fournir un profil de levée de décompression optimisé associé aux états de transition du fonctionnement du moteur.
