| description | The device has a body with a fuel supply pipe that is terminated at a downstream end of the device by an injection nozzle. The nozzle has a set of injection holes (3) permitting spraying of fuel into a combustion chamber of a diesel engine. An inner surface of the pipe has an obstacle (4) placed between two inlets of the holes. The obstacle has a wall longitudinally extending along the axis of the device.
Dispositif d'injection (2) de carburant sous pression pour moteur à combustion interne comportant un corps globalement cylindrique d'axe vertical, comportant une conduite principale (7) d'admission du carburant se terminant à l'extrémité aval du dispositif par un nez (10) d'injection comportant une pluralité de trous (3) d'injection permettant la pulvérisation du carburant dans une chambre de combustion du moteur, caractérisé en ce que la surface interne de la conduite (7) principale d'admission comprend au moins un obstacle (4) en saillie entre au moins deux entrées de trous (3) d'injection, la forme et les dimensions de chaque obstacle (4) étant choisies pour empêcher la formation de phénomènes de cavitation (C) dans le nez d'injection (10). |
