Zusammenfassung
(EN)

The invention relates to a fuel injection valve (1), especially an injection valve for fuel injection systems of internal combustion engines, which comprises a piezoelectric or magnetorestrictive actuator (4) that actuates, by means of a hydraulic coupler (13), a valve closing body (18) that is configured on a valve needle (17) and that interacts with a valve face (20) to give a sealing seat. The hydraulic coupler (13) is provided with a master piston (12) and a slave piston (14). A coupler gap (15) defined between the master piston (12) and the slave piston (14) is dimensioned so as to be closed when the fuel injection valve is cold and to gradually open due to a temperature-induced length change of the actuator (4) with increasing temperature of the fuel injection valve (1).

본 발명은 연료 분사 밸브, 특히 내연기관의 연료 분사 장치용 분사 밸브에 관한 것으로, 유압 커플러(13)에 의해 밸브 니들(17)에 설치된 밸브 폐쇄 바디(18)를 작동시키는 압전 또는 자기 변형 액추에이터(4)를 포함하고, 상기 밸브 폐쇄 바디는 밸브 시이트 면(20)과 함께 밀봉 시이트를 형성한다. 유압 커플러(13)는 마스터 피스톤(12) 및 종속 피스톤(14)을 포함한다. 마스터 피스톤(12)과 종속 피스톤(14) 사이에 형성된 커플러 갭(15)은 연료 분사 밸브의 저온 상태에서 폐쇄되고 연료 분사 밸브(1)의 온도 증가에 따라 액추에이터(4)의, 온도에 따른 길이 변화에 의해 개방되도록 설계된다.
