Abstract

Patente de Invenção: <B>"VáLVULA DE INJEçãO DE COMBUSTìVEL"<D>. Uma válvula de injeção de combustível (1), em particular, uma válvula de injeção para instalações de injeção de combustível de máquinas de combustão interna, abrange um atuador da válvula (4) piezelétrico ou magnetostritivo, e um corpo de fechamento da válvula (20) acionável pelo atuador da válvula (4) por meio de um corpo de acionamento (15) e/ou de uma agulha da válvula (19), o qual atua em conjunto com uma superfície de assento da válvula (21) para um assento hermético. O corpo de acionamento (15) ou a agulha da válvula (19) pode ser ligado através de, pelo menos, um atuador de encalcar (10), com fecho devido à força, com o atuador da válvula (4).
