Abstract

a. Dispositif de commande d'une installation d'alimentation en carburant pour la mise en régime d'un moteur à combustion interne. b. Dispositif caractérisé en ce que, pour élever la chute de pression sur la soupape de mesure du carburant, pendant la phase de mise en régime du moteur à combustion interne, la partie mobile de la soupape de commande de pression est susceptible d'être sollicitée, dans la direction de fermeture, par un autre ressort auquel s'oppose un élément dépendant de la température, de façon telle que ce ressort, après achèvement de la phase de mise en régime, ne vient plus en prise avec la partie mobile de la soupape. c. L'invention s'applique à la commande d'alimentation de moteurs à combustion interne.at. Device for controlling a fuel supply system for starting up an internal combustion engine. b. Device characterized in that, in order to increase the pressure drop on the fuel metering valve, during the start-up phase of the internal combustion engine, the moving part of the pressure control valve is liable to be stressed, in the closing direction, by another spring against which a temperature-dependent element opposes, so that this spring, after completion of the setting-up phase, no longer engages with the moving part of the valve . vs. The invention applies to the supply control of internal combustion engines.
