Abstract

유체를 미입화하여 여러방향으로 분무함과 동시에 용이하게 제조할 수 있는 유체분사노즐은 제공함을 목적으로 하며, 제1오리피스판(70)은 금속으로 되었고, 중앙부에 슬릿형상의 제1오리피스(71)가 형성되어 있다. 제2오리피스(74)도 금속으로 되었고, 2개의 제2오리피스(75)및 (76)이 연료 흐름의 하류에 감에 따라서 끝이 가늘게 되도록 형성되어 있다. 제2오리피스(75)의 상류측 개구부와 하류측 개구부 및 제2오리피스(76)의 상류측 개구부와 하류측 개구부는 편심하여 형성되어 있다. 이 때문에, 제2오리피스(75)및 (76)을 통과하는 연료는 이 편심방향으로 안내되므로, 가장 적합한 분무방향을 구비한 유체분사노즐을 얻을 수 있다.
