Abstract

Patente de Invenção: <B>"VáLVULA DE INJEçãO DE COMBUSTìVEL PARA MOTORES DE COMBUSTãO INTERNA"<D>. é proposta uma válvula de injeção de combustível para motores de combustão interna, com um corpo de válvula (1), em cuja região, do lado da câmara de combustão, é disposto um membro de valvúla (10) em forma de pistão, axialmente móvel em uma perfuração (11) contra a força de uma mola de fechamento (33), o qual por meio de seu movimento de curso de abertura, dirigido para dentro, controla ao menos uma abertura de injeção (16, 17) que é configurada na parede da perfuração (11). O membro de válvula (10) apresenta uma transição, em posição afastada da câmara de combustão, para um disco de mola (30) que é disposto em um compartimento de mola (36) que acolhe a mola de fechamento (33), e em cuja superfície frontal, afastada da câmara de combustão, é configurada uma superfície de esbarro de válvula (18). Na região do corpo de válvula (1). afastada da câmara de combustão, está disposto um pistão de controle (43), o qual limita um compartimento de controle hidráulico (56), salienta-se até o interior do compartimento de mola (36) e sua superfície frontal, voltada para a câmara de combustão, forma uma superfície de esbarro de curso (44). Na dependência da pressão no compartimento de controle (56), o pistão de controle (43) pode ser movimentado contra a força de fecho de uma mola de reposição (53) a partir de uma primeira posição de curso, remota ao membro de válvula (10), no membro de válvula (10), para uma segunda posição de curso, onde o pistão de controle (43) limita o curso de abertura máximo (h) do membro de válvula (10) para um curso parcial (h~ T~).
