Abstract

"VáLVULA DE INJEçãO DE COMBUSTìVEL". A invenção refere-se a uma válvula de injeção de combustível (1), em particular, uma válvula de injeção para instalações de injeção de combustível de máquinas de combustão interna, apresenta um atuador (8) piezoeléctrico ou magnetostritivo, uma agulha da válvula (1 5) acionável pelo atuador (8) por meio de um dispositivo hidráulico de compensação de temperatura e um corpo de fechamento da válvula (28) acionável pela agulha da válvula (15) que atua em conjunto com uma superfície de assento da válvula (14) para formar um assento hermético. Nesse caso, o dispositivo hidráulico de compensação de temperatura abrange uma cápsula de arrasto da agulha (31) a qual agarra em torno de um flange da agulha da válvula (32) da agulha da válvula (15), e com um flange de arrasto da agulha (33) circunda a agulha da válvula (15) por seção. Além disso, a cápsula de arrasto da agulha (31) inclui uma câmara de compensação de temperatura (27) com a agulha da válvula (15) e que, para o enchimento da câmara de compensação de temperatura (27) com combustível, a câmara de compensação de temperatura (27) está ligada com uma entrada de combustível (4) da válvula de injeção de combustível (1), através de uma válvula de direção (29).
