Abstract

"VáLVULA DE INJEçãO DE COMBUSTìVEL". Uma válvula de injeção de combustível (1) para instalações de injeção de combustível de motores de combustão interna, compreende uma agulha de válvula (3) e um corpo de fechamento de válvula (4) em ligação efetiva com a mesma, que coopera com uma superfície de base de válvula (6) disposta em um corpo de base de válvula (5) para formar uma base de vedação, e várias aberturas de ejeção (7) as quais estão dispostas em um disco de furos de ejeção (31), que é disposto corrente abaixo da base de vedação na válvula de injeção de combustível (1). O disco de furos de ejeção (31) possui pelo menos na área das aberturas de ejeção (7) uma curvatura em forma de calota (37) a qual é orientada contra a direção da corrente do combustível, e as aberturas de ejeção (7) estão dispostas em forma de espiral na curvatura em forma de calota (37) do disco de furos de ejeção (31).
