Abstract

"VáLVULA PARA CONTROLE DE UMA LIGAçãO EM UM SISTEMA HIDRáULICO DE ALTA PRESSãO, ESPECIALMENTE UM DISPOSITIVO DE INJEçãO DE COMBUSTìVEL PARA UM MOTOR DE COMBUSTãO INTERNA". A presente invenção refere-se a uma válvula que apresenta um elemento de válvula (72), que é guiado deslocável na direção de seu eixo longitudinal (73), que se projeta para dentro de um compartimento de pressão de válvula (77), no qual predomina ao menos parcialmente alta pressão, e no compartimento de pressão de válvula (77) em um lado frontal se estendendo transversalmente a seu eixo longitudinal (73) apresenta uma área de vedação (81), com a qual coopera com uma sede de válvula (79) se estendendo transversalmente a seu eixo longitudinal (73) para fechamento ao menos amplamente de uma abertura (78) envolta pela sede de válvula (79) relativamente ao compartimento de pressão de válvula (77). à abertura (78) se conecta uma ligação (64) para uma região de baixa pressão, caracterizada pelo fato de que o elemento de válvula (72) apresenta um pino (83) projetado para dentro da ligação (64), pelo qual, com elemento de válvula (72) levantado com sua área de vedação (81) da sede de válvula (79), fluido escoando do compartimento de pressão de válvula (77) é de tal maneira conduzido que por ele não é exercida ao menos aproximadamente qualquer força ou apenas uma ligeira força resultante sobre o elemento de válvula (72) na direção de seu eixo longitudinal (73).
