Abstract
L'invention concerne un interjecteur-pompe pour moteur à allumage par compression d'air. Le piston de pompe 4 présente deux parties 6, 11 assurant respectivement le réglage du débit et celui de la section de passage; un premier conduit 20 assure la communication permanente entre la chambre de refoulement 18 de la pompe et la chambre 20 de l'injection, par l'intermédiaire d'un orifice calibré 23; un deuxième conduit 22, coopérant avec une partie 11 du piston de pompe 2 réglant la section de passage, assure la communication entre cex deux chambres 18, 20 par intermittence. Application à l'amélioration de la régularité et de la stabilité de marche d'un moteur Diesel à régime rapide.
