Abstract

a presente invenção refere-se a uma válvula injetora de combustível (10) que apresenta uma válvula intermediária, cujo membro de válvula intermediária (78) está projetado em forma de cogumelo. a haste (76) do membro de válvula intermediária (78) acha-se guiada na passagem de guia (74) de um componente intermediário (66) em um ajuste deslizante estreito. a haste (76) e a cabeça (80) do membro de válvula intermediária (78) e o componente intermediário (66) delimitam um espaço anelar (120), no qual desemboca uma admissão de alta pressão (86) e o qual é formado por um espaço anelar interno (108) e por um espaço anelar de lacuna (118). o espaço anelar de lacuna (118) está delimitado pela cabeça (80) e pelo componente intermediário (66), bem como, radialmente por fora, por uma saliência de vedação (112). a força de aderência entre o membro de válvula intermediária (78) e o componente intermediário (66), a qual atua contra o movimento de abertura do membro de válvula intermediária (56), encontra-se minimizada.
