Abstract

Patente de Invenção: <B>"VáLVULA DE INJEçãO DE COMBUSTìVEL"<D>. Uma válvula de injeção de combustível (1), especialmente uma válvula de injeção de combustível para instalações de injeção de combustível de máquinas de combustão interna (51), apresenta um atuador piezoelétrico ou magnetostrictivo (14), um corpo de fechamento da válvula (8) acionável pelo atuador (14) por meio de uma agulha de válvula (9), que exerce interação com uma face da sede de válvula (7) a um assento vedado e, pelo menos, uma abertura de injeção (10,11) vedada pelo assento vedado. No caso, a face da sede de válvula (7) e/ou o corpo de fechamento da válvula (8) apresenta regiões parciais (30a, 30b) dispostas deslocadas pelo periferia que estrangulam uma corrente de combustível, de maneira distinta, em função de um curso de agulha da válvula da agulha da válvula (9).
