Title (EN) ROCKER ARM ARRANGEMENT FOR DUAL VALVE TIMING WITH SINGLE CAM LOBE
(FR) LONGUEUR D'EVENEMENT DE SOUPAPE DOUBLE A BOSSAGE UNIQUE
Abstract: front page image
(EN)A valve control system for an engine poppet valve (V) moveable between open and closed positions. A camshaft (11 ) has a cam profile including a lift portion (15), the valve control system comprising a rocker arm (19) defining a pivot location (R) about which the rocker arm pivots to move the poppet valve. The rocker arm includes a first cam follower (35) engaging the lift portion as said camshaft rotates, and is characterized by including a second cam follower (43) engaging the lift portion at approximately the same time the lift portion moves out of engagement with the first cam follower. The second cam follower is moveable between an activated position (FIG. 1 ) in which engagement with the lift portion maintains the poppet valve open, and a deactivated position (FIG. 3) in which engagement with the lift portion does not maintain the poppet valve open.
(FR)L'invention concerne un système de commande de soupape pour une soupape circulaire de moteur (V) mobile entre des positions ouverte et fermée. Un arbre à cames (11) possède un profil de came comprenant une partie de levage (15), le système de commande de soupape comprend un culbuteur (19) définissant un emplacement pivotant (R) autour duquel le culbuteur pivote afin de déplacer la soupape circulaire. Le culbuteur comprend un premier galet de came (35) couplé à la partie de levage lorsque l'arbre à cames pivote, et est caractérisé en ce qu'il comprend un second galet de came (43) couplé à la partie de levage approximativement en même temps que la partie de levage se désengage du premier galet de came. Le seconde galet de came est mobile entre une position activée (FIG. 1 ) dans laquelle le couplage avec la partie de levage maintient l'ouverture de la soupape circulaire, et une position désactivée (FIG. 3) dans laquelle le couplage avec la partie de levage ne maintient pas ouverte la soupape circulaire.
