Abstract

"DISPOSITIVO DE INJEçãO DE COMBUSTìVEL PARA MáQUINA DE COMBUSTãO INTERNA". No caso de um dispositivo de injeção de combustível (1) para máquinas de combustão interna, respectivamente, com um válvula de injeção (6) prevista em uma rede de admissão (5) do combustível, para cada cilindro da máquina de combustão interna, e com um encosto do curso (19) hidráulico que limita o curso de abertura do membro da válvula (11) da válvula de injeção (6) que é construído como câmara de amortecimento (21) hidráulica e apresenta uma válvula de comando de curso (24) que pode ser comandada hidraulicamente que, dependendo da pressão que atua em sua rede de comando (25), bloqueia a ligação da câmara de amortecimento (21) para o lado do óleo de fugas (3), as redes de comando (25) das válvulas de comando de curso (24) individuais podem ser ligadas, através de uma unidade da válvula de comando, ou com um reservatório de baixa pressão (26) ou com o lado do óleo de fugas (3).
