Abstract

MEMBRO DE FIXAçãO E ESTRUTURA DE MONTAGEM PARA VáLVULA DE INJEçãO DE COMBUSTìVEL. Em um membro de fixação para uma válvula de injeção de combustível que fixa um corpo regulador (1), uma válvula de injeção de combustível (10) tendo uma porção de injeção de combustível (11) em uma extremidade sua inserida em um furo de montagem (4) provido em um corpo regulador (1) e é formado por moldar integralmente uma porção de tampa (21), uma porção de junção de combustível (27) e uma porção de ressalto de montagem (26) de uma resina sintética de modo que a porção de junção de combustível (27) à qual um tubo de fornecimento de combustível 33 é conectada e a porção de bossa de montagem (26) que é conectada ao corpo regulador (1) são integralmente conectadas à porção de tampa (21) que é ajustada de modo estanque ao líquido em uma periferia externa de uma porção de entrada de combustível (12) em uma outra extremidade da válvula de injeção de combustível (10), a porção de ressalto de montagem (26) é conectada à porção de tampa (21) em uma região que fica fora na direção axial, de uma superfície de ajuste (22) à porção de entrada de combustível (12), em uma periferia interna da porção de tampa (21). Assim, durante a moldagem de um membro de fixação para uma válvula de injeção de combustível, a contração térmica da porção de ressalto de montagem não influencia a superfície periférica interna da porção de tampa e a estanqueidade a liquido de uma porção de ajuste da porção de entrada de combustível da válvula de injeção de combustível e da porção de tampa pode ser assegurada.
