Abstract

"VáLVULA DE INJEçãO DE COMBUSTìVEL PARA MáQUINAS DE COMBUSTãO INTERNA". Válvula de injeção de combustível, com um corpo da válvula (1), e um furo (3), executado como furo cego, cuja superfície do fundo é virada para a câmara de combustão. Na superfície do fundo é configurada uma sede da válvula cónica (9), dentro da qual é disposta pelo menos uma abertura de injeção (11). Dentro do furo (3), é disposto um elemento de válvula (5), em forma de êmbolo, deslocável em termos longitudinais contra uma força de fechamento, o qual apresenta uma ponta do elemento de válvula (7), o qual, em posição de fechamento do elemento de válvula (5), encosta na sede da válvula (9). Na ponta do elemento de válvula (7), é disposta uma primeira superfície cónica (30), e uma segunda superfície cónica (32), disposta no lado da câmara de combustão em relação à primeira superfície cónica, sendo que o ângulo do cone (<244>) da primeira superfície cónica (30) é menor que o ângulo do cone (<sym>) da sede da válvula (9), o qual por sua vez é menor que o ângulo do cone (<225>) da segunda superfície cónica (32). Entre a primeira superfície cónica (30), e a segunda superfície cónica (32), é configurada uma ranhura anelar (35), e na segunda superfície cónica (32) é disposta uma segunda ranhura anelar circundante (42), a qual, em posição de fechamento do elemento de válvula (5), sobrepõe-se pelo menos parcialmente com as aberturas de injeção (11), com o intuito de alimentar de maneira uniforme com combustível todas as aberturas de injeção (11), também quando o elemento de válvula (50), é desviado em termos axiais.
