Abstract

"VáLVULA DE INJEçãO DE COMBUSTìVEL". Uma válvula de injeção de combustível (1), especialmente para a injeção direta de combustível para dentro da câmara de combustão de uma máquina de combustão interna, com compressão de mistura e com ignição à centelha, compreende um induzido (20), o qual coopera com uma bobina de eletroímã (10), e uma agulha de válvula (3), ligada com o induzido (20), na qual é previsto um corpo de fechamento da válvula (4), o qual forma, junto com uma superfície da sede de válvula (6), uma sede de vedação. A agulha de válvula (3), a jusante do induzido (20), apresenta uma bucha de aperto (31), cuja posição axial na agulha de válvula (3), determina a altura de uma fenda do curso prévio (38), configurada entre o induzido (20), e um flange de arrasto (21), ligado por fecho pela fricção com a agulha de válvula (3), sendo que a bucha de aperto (31), é configurada em forma de tubo, e apresenta uma fenda (33), que passa em direção axial.
