Abstract

Dispositif de sécurité pour soupape d'injection à pres­ sion constante de moteur à combustion interne. Suivant l'invention, il obture la canalisation principale d'alimentation (14) de cette soupape de façon permanente et définitive en cas de dépassement de la quantité maximale admissible de carburant injectée ou de dépassement de la fréquence de commande pour une quantité injectée donnée, inférieure la quantité maximale admissible.
Application : notamment à l'injection diesel du type pression - temps.
