Abstract
Patente de Invenção:<B>"VáLVULA INJETORA DE COMBUSTìVEL"<D>. A invenção refere-se a uma válvula injetora de combustível, com um dispositivo de manobra (10, 11,12) excitável, com uma agulha de válvula (5) axialmente móvel pelo dispositivo de manobra (10, 11, 12), que está unida com um corpo de fechamento de válvula (7). O corpo de fechamento de válvula (7) interage com uma superfície de assento de válvula (29), para abertura e fechamento da válvula. Corrente abaixo da superfície de assento de válvula (29) está disposto um disco perfurado (21), que com uma parte de fundo (22) e uma borda de retenção (26) que se salientam da mesma está formado em forma de concha ou copo. O disco perfurado (21) fino, que consiste em uma chapa, apresenta na área de transição da parte de fundo (22) para a borda de retenção (26) entalhes (36) que aumentam a rigidez do disco perfurado (21). A válvula injetora de combustível é particularmente apropriada para sistemas injetores de combustível de máquinas de combustão interna, compressoras de mistura, de ignição externa.
