Abstract

VáLVULA PARA INJEçãO DE COMBUSTìVEL ELETROMAGNéTICA E PROCESSO PARA PRODUçãO DA MESMA. Em uma válvula para injeção de combustível eletromagnética projetada de modo que o contato da face de atração móvel em uma extremidade traseira de um núcleo móvel com uma face de atração estacionária incluída em ma extremidade dianteira de um núcleo estacionário seja inibido, um batente em formato de anel (28) feito de um material não-magnético ou fracamente magnético mais do que um núcleo móvel (18) é ajustado sob pressão em uma periferia interna de uma porção traseira do núcleo móvel (18) e uma face de topejamento plana (51), que é disposta em um local deslocado de uma face de atração móvel plana (41) formada na extremidade traseira do núcleo móvel (18) para uma face de atração estacionária (42), é formada na extremidade traseira do batente (28) para ser capaz de topejar-se contra a face de atração estacionária. Uma inclinação (52) é formada em uma periferia interna da extremidade traseira do núcleo móvel (18) e uma periferia externa da extremidade traseira do batente (28) para contínua e niveladamente conectar a face de atração móvel (41) e a face de topejamento 5l entre si. Assim, o acúmulo e deposição de fragmentos e um pó magnético podem ser prevenidos e a área de aplicação da força de atração eletro-magnética ao núcleo móvel pode ser aumentada substancialmente, enquanto descrescendo o número de peças e o número de etapa de montagem para proporcionar uma redução no custo.
