Abstract

L'invention concerne un démarreur (10) pour un moteur à combustion interne, comportant un moteur de démarreur (12) pouvant être accouplé au moteur à combustion interne au moyen d'un pignon (22), et un dispositif destiné à engrener le pignon (22) dans une couronne dentée (26) du moteur à combustion interne, et à connecter le moteur de démarreur (12) à un réseau de tension continue (30, 31). Pour désaccoupler les processus de travail, le dispositif comporte des éléments séparés, notamment des relais séparés (57, 64; 60), d'une part destinés à engrener le pignon (22) et d'autre part à mettre en marche le moteur de démarreur (12) lors du démarrage du moteur à combustion interne. Il est ainsi possible d'éviter des effets rétroactifs de la dynamique d'engrènement sur le système de contact lors de la commutation du courant moteur.
