Abstract

L'invention porte sur un dispositif de commande d'arrêt pour moteur. Le dispositif peut réduire une vibration du moteur à l'arrêt du moteur en même temps que la collision d'un élément soupape d'une soupape de limitation d'admission. Le dispositif de commande d'arrêt comporte la soupape de limitation d'admission (13) disposée sur le trajet d'admission (11) du moteur (1) de façon à pouvoir être ouverte et fermée et à ouvrir et fermer le trajet d'admission (11) ainsi que des moyens de commande (14) pour commander la soupape de limitation d'admission (13). A l'arrêt du moteur (1), les moyens de commande (14) commandent la soupape de limitation d'admission (13) de telle sorte que ladite soupape de limitation d'admission (13) arrive rapidement à un degré d'ouverture prédéterminé proche d'une position entièrement fermée sans provoquer un impact important lorsque ladite soupape de limitation d'admission (13) ferme le trajet d'admission (11), la fermeture de la soupape de limitation d'admission (13) se faisant plus lentement jusqu'à la position entièrement fermée que jusqu'au degré d'ouverture prédéterminée proche de la position entièrement fermée.
