Abstract

"INJETOR DE COMBUSTìVEL COM VáLVULA DE INJEçãO PROVIDA COM ALIMENTAçãO LATERAL". Um injetor de combustível (1) provido com uma válvula de injeção (7) compreendendo um êmbolo móvel (15); um jato de injeção (3) tendo uma pluralidade de primeiros furos atravessantes (24) feitos partindo de uma câmara (25) disposta à jusante da válvula de injeção (7); um corpo de suporte (4) tendo uma forma tubular e compreendendo um canal de suprimento (5); e um corpo de vedação (17) no qual uma sede de válvula (16) da válvula de injeção (7) é definida, e o jato de injeção (3) é produzido; o corpo de vedação (17) é monolítico e tem um membro de batoque em forma de disco (18) passado através pelo jato de injeção (3), e um membro de guia (19) que se eleva para cima a partir do membro de batoque (18), é tubular na forma, e recebe dentro dele o êmbolo (15), e tem um diâmetro externo menor do que o diâmetro interno do canal de suprimento (5), de modo a definir um canal externo (20) para o combustível; na parte inferior do membro de guia (19) são providos um número de segundos furos atravessantes (21) que se abrem na sede de válvula (16).
