Abstract

Patente de Invenção: <B>"VáLVULA DE INJEçãO DE COMBUSTìVEL"<D>. A invenção refere-se a uma válvula de injeção de combustível para máquinas de combustão interna com um membro de válvula (11) deslocável axialmente para fora em um furo (9) de um corpo de válvula (1) ao encontro da força de uma mola de fecho (31), o qual em sua extremidade no lado da câmara de combustão, apresenta uma cabeça de fechamento (13) que se projeta para fora do furo, formando um membro de fechamento da válvula, a qual em seu lado voltado para o corpo de válvula (1) apresenta uma superfície de vedação da válvula (15) com a qual ela atua em conjunto com uma superfície de assento da válvula (17) disposta no lado frontal do corpo de válvula (1) no lado da câmara de combustão, e com pelo menos uma abertura de injeção na cabeça de fechamento que parte de uma câmara de pressão (19) cuja abertura de saída na posição de fechamento do membro de válvula (11) é coberta pelo corpo de válvula (1) e é liberada com curso de abertura direcionado para fora. A fim de aumentar a duração da válvula de injeção de combustível, um dispositivo hidráulico de amortecimento de fecho (37, 39, 41, 43, 45, 47) está integrado na válvula de injeção de combustível.
