Title
(EN) ROCKER ARM ASSEMBLY
(FR) ENSEMBLE CULBUTEUR
Abstract
(EN)
A valve train assembly includes a first exhaust valve, a second exhaust valve, and a valve bridge including a main body and a lever rotatably coupled to the main body, the main body configured to engage the first exhaust valve, and the lever configured to engage the second exhaust valve. An exhaust valve rocker arm assembly is configured to selectively open the first and second exhaust valves, the exhaust valve rocker arm assembly including an exhaust valve rocker arm with a hydraulic lash adjuster (HLA) assembly coupled thereto, the HLA assembly in contact with the valve bridge main body. An engine brake rocker arm assembly is configured to selectively open the second exhaust valve and including an engine brake rocker arm with a combined HLA and added motion capsule coupled thereto. The combined HLA and added motion capsule is configured to selectively engage and rotate the lever.

La présente invention concerne un ensemble train de soupapes comprenant une première soupape d'échappement, une seconde soupape d'échappement et un pont de soupape comprenant un corps principal et un levier couplé rotatif au corps principal, le corps principal étant conçu pour venir en prise avec la première soupape d'échappement, et le levier étant conçu pour venir en prise avec la seconde soupape d'échappement. Un ensemble culbuteur de soupape d'échappement est conçu pour ouvrir sélectivement les première et seconde soupapes d'échappement, l'ensemble culbuteur de soupape d'échappement comprenant un culbuteur de soupape d'échappement doté d'un ensemble dispositif de réglage de jeu hydraulique (HLA) couplé à celui-ci, l'ensemble HLA étant en contact avec le corps principal de pont de soupape. Un ensemble culbuteur de frein moteur est conçu pour ouvrir sélectivement la seconde soupape d'échappement et comprend un culbuteur de frein moteur avec un HLA et une capsule de mouvement ajoutée combinés couplés à celui-ci. Le HLA et la capsule de mouvement ajoutée combinés sont configurés pour venir en prise avec le levier et faire tourner ledit levier de manière sélective.
