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. Safety device for injection valve near constant load of internal combustion engine. following the invention, it closes the main supply line (14) of this valve permanently and permanently in if the maximum admissible quantity of fuel injected or exceeding the frequency of order for a given quantity injected, less than maximum allowable quantity.

Application : notamment à l'injection diesel du type pression - temps. Application: in particular to diesel injection of the type pressure - time.
