Abstract

본 발명은 2단 연료 분사 밸브에 관한 것이다. 본 발명의 2단 연료 분사 밸브는, 인젝션 펌프에서 압송되는 주연료의 압력을 제1 주연료 챔버(206)에서 플런저(400)에 작용하도록 하고, 이어서 플런저(400)를 통해 보조연료 가압챔버(302)에 전달하여 보조연료를 가압하며, 보조연료의 가압에 의해 니들(400)을 슬라이드 밸브 방식으로 후퇴시켜 보조연료 노즐홀(204)을 개방하여 보조연료를 분사하며, 보조연료 분사 후 주연료 노즐홀(202)을 개방하여 주연료를 분사함으로써 2단의 연료분사를 할 수 있도록 한 것이다. 또한, 주연료와 보조연료 통로(110, 210)(120, 220, 230) 및 노즐홀(202, 204)을 하나의 바디(100a)에 2원화하여 배치함으로써 2종 연료를 분사할 수 있도록 한 것이다.
