Abstract
a. Injecteur électromagnétique de carburant pour moteurs à combustion interne. b. Injecteur caractérisé en ce que dans l'alésage de retour de la chambre de tourbillonnement est prévu un robinet auxiliaire à soupape, dont l'élément de fermeture est fonctionnellement couplé avec la soupape qui contrôle l'ouverture de pulvérisation et qui ferme l'alésage de retour, lorsque la soupape libère l'ouverture de pulvérisation et inversement. c. L'invention trouve son application dans le domaine des injecteurs électromagnétiques de carburant pour moteurs à combustion interne.
