Kraftstoffzuleitungseinrichtung

摘要

The invention relates to a fuel supply device for a fuel injection nozzle situated in the cylinder head of an internal combustion engine, comprising a stub pipe extending through an opening in the cylinder head, which is tightly joined to the connecting piece of a feeder pipe on the inflow side and which is axially pressed with a support surface against a conical seating (12) of the fuel injection nozzle on the outflow side, which seating is positioned against a nozzle holder (10) by means of a cap screw screwed into the opening in the cylinder head. Said device is characterized in that a non-return valve (20, 30) is situated downstream from the conical seating (12) in the supply channel (14) of the injection nozzle and that said valve allows fuel to be delivered exclusively in the direction of the combustion chamber of the internal combustion engine.
