Abstract

"VáLVULA DE INJEçãO DE COMBUSTìVEL". Uma válvula de injeção de combustível para instalações de injeção de combustível de máquinas de combustão interna compreende um corpo de fechamento da válvula (4) que está em união ativa com uma agulha da válvula (3) e que exerce interação com uma área da sede da válvula (6) disposta em um recesso do corpo de sede da válvula (5) para formar um assento estanque e com pelo menos uma abertura de injeção (7) disposta no corpo de sede da válvula (5). Entre a área da sede da válvula (6) e a abertura de injeção (7) é configurada pelo recesso do corpo de sede da válvula (5) uma segunda área (36) que forma com o eixo central (37) da válvula de injeção de combustível (1) um ângulo mais agudo (p) do que a área da sede da válvula (6). Na extremidade a jusante do corpo de fechamento da válvula (4) é disposto um prolongamento de corpo de fechamento (35) cuja superfície lateral (39) forma com o contorno adjacente do corpo de fechamento da válvula (4) um ângulo obtuso.
