Abstract

Patente de Invenção: <B>"INJETOR DE COMBUSTìVEL"<D>. Um injetor de combustível possuindo passagens de equalização de pressão é fornecida para equalizar o diferencial de pressão através de uma armadura em combustíveis de pressão de vapor alta. Está incluída pelo menos uma passagem direta que se estende de uma câmara abaixo da armadura para a câmara no topo da armadura para impedir a formação de pressão diferencial quando o injetor está fechado. As passagens permitem a comunicação entre as áreas acima e abaixo da armadura para equalizar rapidamente a pressão que atua na armadura quando as bolhas de ebulição estouram e o combustível "explode".
