Abstract (en)

The present disclosure refers to an injection nozzle system (10) that may comprise a needle (12), a needle guide member (14) comprising a bore (19) configured for guiding the needle (12) between a fuel injection state and a closed state of the injection nozzle system (10), and a nozzle hood (30) surrounding essentially the needle guide member (14) with the exception of a face of the needle guide member (14) at a nozzle holder side of the injection nozzle system (10). The nozzle hood (30) may comprise a blind hole (22) fluidly connected via an opening to a high pressure fuel path of the injection nozzle system (10) and via a plurality of nozzle spray holes (24) to an outside of the nozzle hood (30) at an injection side of the injection nozzle system (10). The bore (19) of the needle guide member (14) may be configured to provide a high pressure chamber (20) within an upper third of the needle guide member (14) next to the nozzle holder side and a high pressure supply bore (46) may be configured to connect the high pressure chamber (20) with the face of the needle guide member (14) at the nozzle holder side and to be inclined with respect to a longitudinal axis (23) of the nozzle system (10) at an angle greater than 20°.
