Abstract
"DISPOSITIVO DE ALTA PRESSãO PARA COMBUSTìVEL". Dispositivo de alta pressão para combustível, com uma caixa (1), a qual circunda um primeiro corpo de alta pressão (3), e um segundo corpo de alta pressão (5), os quais, em uma superfície de encosto (30), se encostam um no outro. Através da superfície de encosto (30), passa um espaço de alta pressão (23), configurado na caixa (1), dentro do qual, pelo menos temporariamente, existe uma pressão de combustível alta. Uma parte de parede (7), que apresenta um eixo longitudinal (15), circunda a caixa (1), pelo menos na região da superfície de encosto (30), assim que entre a parte de parede (7), e a caixa (1), é configurado um espaço para óleo de fuga (32), o qual está vedado para fora.
