Title (EN) ROCKER ARM ASSEMBLY HAVING AN ELECTRICAL CONNECTION MADE BETWEEN ABUTTING SURFACES THAT UNDERGO RELATIVE MOTION
(FR) ENSEMBLE CULBUTEUR AVEC CONNEXION ÉLECTRIQUE RÉALISÉE ENTRE DES SURFACES DE BUTÉE SUBISSANT UN MOUVEMENT RELATIF
Abstract:
(EN) A valvetrain for an internal combustion engine of the type that has a combustion chamber, a moveable valve having a seat formed in the combustion chamber, and a camshaft includes a rocker arm assembly, a pivot providing a fulcrum for a rocker arm of the rocker arm assembly, and a latch assembly. An electrical device mounted to the rocker arm assembly receives power or communicates through a circuit that includes an electrical connection formed by abutment between surfaces of two distinct parts. The rocker arm assembly is operative to move one of the two abutting surfaces relative to the other in response to actuation of the cam follower. Forming an electrical connection through abutting surfaces that are free to undergo relative motion may reduce or eliminate the need to run wires to a mobile portion of the rocker arm assembly.
(FR) L'invention concerne une distribution à soupapes destinée à un moteur à combustion interne du type comprenant une chambre de combustion, une soupape mobile comportant un siège formé dans la chambre de combustion, et un arbre à cames comprenant un ensemble culbuteur, un pivot formant un point d'appui pour un culbuteur de l'ensemble culbuteur, et un ensemble de verrouillage. Un dispositif électrique monté sur l'ensemble culbuteur reçoit du courant ou communique par l'intermédiaire d'un circuit comportant une connexion électrique formée par le contact entre les surfaces de deux parties distinctes. L'ensemble culbuteur permet de déplacer l'une des deux surfaces de butée par rapport à l'autre en réponse à un actionnement du galet suiveur. La formation d'une connexion électrique par l'intermédiaire de surfaces de butée qui sont libres de subir un mouvement relatif peut réduire ou supprimer la nécessité d'acheminer des fils jusqu'à une partie mobile de l'ensemble de culbuteur.
