Definitions

  • a storage space filled with fuel into which the pressure line opens via a check valve, and in the injection nozzle a pressure chamber that is under the pressure of the fuel in the storage space and extends towards the guide section of the valve needle and acts on it Piston is arranged, the cross section of which is larger than the cross section of the guide portion of the valve needle and its end face facing the guide portion is acted upon by the fuel pressure prevailing in the pressure line upstream of the check valve, and that a channel leading from the storage space to the annular space is present.
