Beschreibung
Zusammenfassung:	The present invention relates to a gas injector having a plurality of valve needles, comprising: a solenoid actuator (2) having an armature (20), an inner pole (21), and a coil (22); at least two outwardly opening valve needles (31, 32, 33) respectively for opening and closing an outlet opening of a gas path on a valve seat (90); and a reset device (10) designed to return the valve needle (31, 32, 33) to a starting position thereof. In particular, the present invention relates to the gas injector for injecting a gas directly into a combustion chamber of an internal combustion engine. 본 발명은 전기자(20), 내극(21) 및 코일(22)을 갖는 솔레노이드 액추에이터(2), 각각 밸브 시트(90) 상의 가스 경로의 배출 개구를 개방 및 폐쇄하는, 적어도 두 개의 외부로 개방되는 밸브 니들들(31, 32, 33), 및 상기 밸브 니들(31, 32, 33)을 시작 위치로 되돌리도록 설계된 리셋 장치(10)를 포함하는, 특히 내연 기관의 연소실로 직접 가스를 분사하기 위한 가스 인젝터에 관한 것이다.
