Abstract

L'invention concerne un corps de buse comportant un évidement d'aiguille de buse disposé autour d'un axe longitudinal, qui comprend un siège d'aiguille de buse conique débouchant dans un trou borgne, ainsi qu'au moins un trou d'injection s'étendant du trou borgne vers une surface extérieure du corps de buse. Dans la zone de transition vers le siège d'aiguille de buse conique, le trou borgne présente un diamètre de trou borgne et s'étend dans la direction axiale, de la zone de transition jusqu'à une profondeur de trou borgne, le rapport diamètre de trou borgne sur profondeur de trou borgne étant supérieur ou égal à 1,5. L'invention concerne également un dispositif composé d'un corps de buse et d'une aiguille de buse, ainsi qu'un injecteur de carburant.
