Abstract

"VáLVULA DE INJEçãO DE COMBUSTìVEL". A presente invenção refere-se a uma válvula de injeção de combustível (1), especialmente uma válvula de injeção de combustível (1) para sistemas de injeção de combustível de motores de combustão interna, compreende um atuador (4) plezelétrico ou magneto-restritivo que pode ser excitado através de pelo menos uma linha elétrica (6) que manipula um corpo de fecho de válvula (20) disposto em uma caixa (2), que age em conjunto com uma superfície de base de válvula (21) para formar uma base de vedação, e um acoplador hidráulico (10). O acoplador hidráulico (10) é disposto de modo estacionário entre o atuador (4) e um módulo de válvula (11) que compreende o corpo de fecho de válvula (20) e a superfície de base de válvula (21).
