Abstract

An injection nozzle (22) for mounting to a nozzle holder of a fuel injection system (1) of an internal combustion engine may comprise a sealing face (29) for providing a sealed connection to the nozzle holder, a needle guiding bore (34) for guiding a needle between a fuel injection state and a sealed state of the fuel injector. The needle guiding bore (34) may extend through the sealing face (29) , being fluidly connected at an injection side of injection nozzle (22) , to an outside of the injection nozzle (22) via a plurality of nozzle spray holes (70). The needle guiding bore (34) may be widened to form a high pressure fuel chamber (36). A high pressure supply bore (38) may extend through the sealing face (29) and fluidly connect an opening in the sealing face (29) with the high pressure fuel chamber (36). A radial outer section (60) of a wall of the fuel supply channel (38) may smoothly transition into a wall of the high pressure fuel chamber (36). The high pressure supply bore (38) may be provided in a drop -like, rounded shape.
