Abstract

Dans des soupapes à commande électromagnétique connues, le débit de fluide distribué pendant le processus d'ouverture et de fermeture est réglé par la variation de la force du ressort de rappel agissant sur le corps de fermeture de soupape. Cependant, à cet effet, il faut prévoir sur la soupape une fois montée une possibilité d'accès au ressort de rappel sous forme d'un élément de réglage d'un accès facile. Dans le procédé selon l'invention pour le réglage du débit du fluide distribué pendant le processus d'ouverture et de fermeture d'une soupape à commande électromagnétique, le couvercle du corps (10) et la chemise de soupape (9) se déplacent l'un par rapport à l'autre, et ainsi la section d'étranglement critique magnétique limitant le flux magnétique du circuit magnétique est modifiée jusqu'à ce que le débit de fluide mesuré et réellement distribué corresponde au débit théorique prédéfini. Le procédé selon l'invention convient en particulier à des injecteurs de carburant à commande électromagnétique de systèmes d'injection de moteurs à combustion interne.
