Abstract

"VáLVULA DE INJEçãO DE COMBUSTìVEL PARA MáQUINAS DE COMBUSTãO INTERNA E UM PROCESSO PARA O ENDURECIMENTO DA MESMA". A Presente invenção refere-se a uma válvula de injeção de combustível para máquinas de combustão interna, com um corpo da válvula (1), e pelo menos uma abertura de injeção (11), configurada neste, através da qual, controlado por uma agulha da válvula (5), a qual coopera com uma sede da válvula (9), configurada no corpo da válvula (1), combustível pode ser injetado para dentro da câmara de combustão da máquina de combustão interna. O corpo da válvula (1), consiste em um aço para trabalho a quente de alto teor de liga, o qual foi endurecido por meio de um processo de carburação (figura 1).
