| description | The subject of the invention is a device for controlling an internal combustion engine valve, which device comprises two cams 11, 12 carried by the same shaft 2 and each interacting with one of the two push rods 13, 14 connected to a member 5 for actuating the valve. According to the invention, the push rod 13 associated with the first cam 11 is rigid whereas the other push rod 14 is telescopic and contains an internal chamber connected to a circuit for supplying pressurised liquid comprising a distributor 31 controlled as a function of at least one parameter of the engine so that this push rod 14 is alternately retracted in an inactive state, especially at low rotational speeds of the engine, or extended in an active state.
L'INVENTION A POUR OBJET UN DISPOSITIF DE COMMANDE D'UNE SOUPAPE DE MOTEUR A COMBUSTION INTERNE, COMPRENANT DEUX CAMES 11, 12 PORTEES PAR UN MEME ARBRE 2 ET COOPERANT CHACUNE AVEC L'UN DES DEUX POUSSOIRS 13, 14 RELIES A UN ORGANE D'ACTIONNEMENT 5 DE LA SOUPAPE.SELON L'INVENTION, LE POUSSOIR 13 ASSOCIE A LA PREMIERE CAME 11 EST RIGIDE TANDIS QUE L'AUTRE POUSSOIR 14 EST TELESCOPIQUE ET CONTIENT UNE CHAMBRE INTERNE RELIEE A UN CIRCUIT D'ALIMENTATION EN LIQUIDE SOUS PRESSION COMPORTANT UN DISTRIBUTEUR 31 COMMANDE EN FONCTION D'AU MOINS UN PARAMETRE DU MOTEUR DE MANIERE QUE CE POUSSOIR 14 SE TROUVE ALTERNATIVEMENT RETRACTE DANS UN ETAT INACTIF, NOTAMMENT A FAIBLE VITESSE DE ROTATION DU MOTEUR, OU ALLONGE DANS UN ETAT ACTIF. |
