Abstract

과제
연소실에 직접 연료를 분사할 수 있고, 사용조건이 과혹한 모형용 엔진에 있어서 연료를 안정적으로 공급한다.
해결수단
케이싱체(31)내의 솔레노이드코일(32)은 공기유지공간(35)을 갖는 자심(34)을 구비한다. 케이싱체(31)내에서 이동가능한 밸브체(50)는 판스프링(54)으로 가세되어 연료분사구(43)를 폐쇄한다. 연료공급로(55)에서 공급된 연료는 케이싱체내의 연료유지공간(56)에 유지된다. 공기유지공간(35)은 공기제어밸브(39)가 폐쇄한다.연료분사구(43)에는 역지밸브(47)가 있다. 밸브체(50)에 고정된 공기관(60)은 공기제어밸브(39)와 역지밸브(47) 사이에 배치된다. 공기유지공간에는 공기압이 공급된다. 코일에 통전하여 밸브체(50)가 좌로 이동하면 연료분사구(43)가 개방되고, 동시에 공기관(60)의 이동에 의해 공기제어밸브(39)가 개방된다. 공기관에서 분사노즐(46)을 향하여 분사되는 공기에 의해 연료는 미세한 안개모양이 되어 연소실내로 분사된다. 역지밸브(47)가 있기 때문에 연소실내의 고압에 의한 연료역류의 염려는 없다.
