Title
(EN) A CONTROL DEVICE FOR THE VALVE OF AN INTERNAL-COMBUSTION ENGINE
(FR) DISPOSITIF DE COMMANDE POUR LA SOUPAPE D'UN MOTEUR À COMBUSTION INTERNE
Abstract
(EN)
A control device for controlling the exhaust or intake valve of an internal-combustion engine; the control device (3) comprising : - a rocker arm (7), which is mounted so as to be rotatable about a first axis (A1) and can be coupled to a shaped shaft (5); - a driving foot (15) configured to act on the valve (2); an actuation device (22, 23, 18, 16) housed within the rocker arm (7) for selectively transmitting a movement between the shaped shaft (5) and the valve (2); an actuation duct (17) in communication with the actuation device (22, 23, 18, 16), the actuation duct (17) being configured to hydraulically enable or disable the actuation device (22, 23, 18, 16).
(FR)
L'invention concerne un dispositif de commande destiné à commander la soupape d'échappement ou d'admission d'un moteur à combustion interne. Ledit dispositif de commande (3) comprend : un culbuteur (7), qui est monté de manière à pouvoir tourner autour d'un premier axe (Al) et qui peut être couplé à un arbre conformé (5); un pied d'entraînement (15) configuré pour agir sur la soupape (2); un dispositif d'actionnement (22, 23, 18, 16) logé à l'intérieur du culbuteur (7) pour transmettre sélectivement un mouvement entre l'arbre conformé (5) et la soupape (2); un conduit d'actionnement (17) en communication avec le dispositif d'actionnement (22, 23, 18, 16), le conduit d'actionnement (17) étant configuré pour activer ou désactiver hydrauliquement le dispositif d'actionnement (22, 23, 18, 16).
