Abstract

L'invention concerne un système d'injection à rampe commune destiné à des moteurs à combustion interne, comportant une pompe haute pression à débit commandé, et un appareil de commande commandant le débit volumétrique et donc la pression de rampe. Selon l'invention, ledit système est pourvu d'une soupape de réduction de pression commandable à action rapide (14, 14a, 19, 20, 22 28), destinée à prélever des quantités minimales de carburant dans la rampe afin de réduire la pression dans le système, sans toutefois descendre en dessous de la pression système souhaitée (PSOLL). Par ailleurs, une comparaison de la pression système de consigne/réelle est effectuée après la réduction de pression, et un nouveau prélèvement de carburant est éventuellement réalisé (réduction de pression) par la soupape de réduction de pression.
