Abstract

Patente de Invenção: <B>VáLVULA DE INJEçãO DE COMBUSTìVEL PARA MOTORES DE COMBUSTãO INTERNA E UM PROCESSO PARA A PRODUçãO DA MESMA"<D>. Válvula de injeção de combustível para motores de combustão interna e um processo para a produção da mesma, com um corpo de base de válvula (2), no qual é disposto um membro de válvula (12), em forma de pistão, móvel axialmente contra a força de ao menos uma mola de fechamento (27, 28), o qual, na extremidade, do lado da câmara de combustão, controla a abertura de ao menos um canal de injeção (19), e, por meio da pressão de combustão sobre um ressalto de pressão (10) configurado no membro de válvula (12), quando do atingimento de uma pressão de abertura, pode ser movimentado na direção axial. Ao menos uma mola de fechamento (27, 28) é disposta sob tensão prévia em um compartimento de mola (30) configurado no corpo de retenção de válvula(1), sendo que ao menos uma mola de fechamento (27, 29), afastado da câmara de combustão, se apóia em um pino de ajuste (31 32). A pressão de abertura, determinada por meio da tensão prévia de ao menos uma mola de fechamento (27, 28), pode se ajustar por meio do deslocamento do pino de ajuste (31, 32) na direção axial por meio de uma ferramenta de ajuste (49) inserível através de uma perfuração de ajuste (52). A posição do pino de ajuste (31, 32) no compartimento de mola (30) é fixada em seguida por meio de recalcamento.Invention Patent: <B> FUEL INJECTION VALVE FOR INTERNAL COMBUSTION ENGINES AND A PROCESS FOR THE PRODUCTION OF THE SAME "<D>. Fuel injection valve for internal combustion engines and a process for the production of the same, with a valve base body (2), in which a piston-shaped valve member (12) is axially movable against the force of at least one closing spring (27, 28), which, at the end , on the side of the combustion chamber, controls the opening of at least one injection channel (19), and, by means of the combustion pressure over a pressure relief (10) configured in the valve member (12), when reaching of an opening pressure, it can be moved in the axial direction. At least one closing spring (27, 28) is placed under previous tension in a spring compartment (30) configured in the valve retaining body (1), at least one closing spring (27, 29), away from the combustion, rests on an adjustment pin (31 32). The opening pressure, determined by pre-tensioning at least one closing spring (27, 28), can be adjusted by displacing the adjustment pin (31, 32) in the axial direction using an adjustment tool (49) insertable through an adjustment hole (52). The position of the adjusting pin (31, 32) in the spring compartment (30) is then fixed by repression.
