Abstract

Soupape miniaturisée d'injecteur de carburant (10) destinée à se loger dans un logement d'injecteur ménagé dans un collecteur de prise d'air (12) d'un moteur à combustion interne pourvu d'un rail de carburant intégré (14). Cette soupape d'injecteur de carburant possède un logement cylindrique magnétiquement perméable (26) pourvu d'orifices d'admission radiaux (24) et d'un passage de guidage d'induit (32). Un élément de siège de soupape (40) pourvu d'un orifice de sortie et d'un siège de soupape (48) est monté à l'extrémité du logement cylindrique (26) présentant le passage de guidage. Une plaque d'orifice (56) possédant un orifice calibré est disposée dans un évidement de plaque d'orifice (50) ménagé dans la face de l'organe de siège de soupape (40). Un stator (76) disposé dans le logement cylindrique présente un élément polaire situé axialement (78) et un bord radial (80) fixé à l'autre extrémité du logement cylindrique. Une bobine de solénoïde est enroulée directement autour de l'élément polaire (78). Un induit (34) est situé réciproquement dans le conduit de guidage (32) et présente un élément de soupape monté sur la face adjacente au siège de soupape, un joint annulaire simple (90) situé à mi-chemin entre les orifices d'admission (24) et la bobine de solénoïde (86) constituant l'unique joint interne de la soupape miniaturisée d'injecteur de carburant. La connexion électrique avec la bobine de solénoïde (86) est garantie par une paire de bornes électriques (94) s'étendant à l'extérieur de la partie arrière de la soupape miniaturisée d'injecteur de carburant à travers le bord radial du stator (80).
