ABSTRACT:
The fuel injection valve for injecting fuel into a combustion chamber of an internal combustion engine comprises a valve housing and nozzle, having a nozzle body 1 with an axial bore 13 which has a slidable but not liquid-tight fitted nozzle needle 3 for reciprocating movement between opened and closed positions. In the upper portion of the axial bore 13 the sealing bellows 5 is fitted. The bottom of the bellows 5 is permanently kept in contact with upper end face of the nozzle needle 3. The bellow's flange is held in liquid-tight fashion between space 8 and top end face of the nozzle body for sealing the clearance between nozzle needle and body. A push rod 6 is the bellows 5 to impart an urging spring force to the nozzle needle 3. During the operation the nozzle needle 3 is lifted in unison with the bellows 5 against increased fuel pressure within the axial bore 13 in addition to the urging force of the nozzle spring 18. Thus a gradual lifting motion of the nozzle needle 3 is achieved and accordingly the fuel injection quantity is gradually increased at the start of the injection.
