Abstract

Une telle soupape est destinée à maintenir constante la différence de pression entre la tuyauterie d'admission d'air du moteur et la pression d'alimentation en carburant des injecteurs. Une soupape régulatrice selon l'invention a un fonctionnement plus précis et est essentiellement caractérisée en ce que l'embouchure 9a du raccord 9 de trop-plein ou de décharge de carburant excédentaire possède un diamètre extérieur de 13 mm et un diamètre intérieur de 10 mm et en ce que le ressort de compression hélicoïdal Il qui tient le clapet 10 normalement appliqué contre l'embouchure 9a présente une élasticité telle que sa force varie de 1 kg pour une course de 3 mm.
