The aim of the invention is to fulfill, better than the prior art, the demands placed by the engine on a variable valve control with regard to the shaping and accuracy of the valve lifting curves with regard to the simplicity of the structural design of the valve drive and of the associated adjusting mechanism and with regard to mechanical losses due to friction. These demands are fulfilled without any additional structural complexity, particularly pertaining to the overall height. This is achieved by the provision of a rotatable drive consisting of a housing (G), a shaft (W), an intermediate element (Z) and of an output element (A).
L'objectif de la présente invention est de répondre, mieux que l'art antérieur, aux exigences d'un moteur relatives à une commande de soupape variable, concernant la configuration et la précision des courbes de levées de soupape, la simplicité de la conception structurale de l'entraînement de soupapes et le mécanisme de réglage correspondant, et concernant les pertes mécaniques liées aux frottements. L'invention répond à ces exigences sans faire appel à une complexité structurelle supplémentaire, relative en particulier à l'encombrement en hauteur. L'objectif de l'invention est atteint au moyen d'un entraînement rotatif constitué d'un logement (G), d'un arbre (W), d'un élément intermédiaire (Z) et d'un élément de sortie (A).
