Abstract

resumo patente de invenção: "válvula de injeção de combustível". a presente invenção refere-se a uma válvula de injeção de combustível para um sistema de injeção de combustível de motores de combustão interna. a válvula de injeção de combustível compreende um elemento eletromagnético que atua com uma bobina magnética (1), com um núcleo (2) e um invólucro de válvula (5) como um componente externo do circuito magnético e um corpo móvel de fechamento de válvula (19) que atua em conjunto com uma superfície de assento de válvula (16) designado a um corpo de assento da válvula (15) associado. o núcleo (2) e um tubo de conexão (44) estão conectados de forma fixa sob a pressão ou a compressão, em uma abertura interna de uma manga da válvula (6) de paredes finas, bem como o invólucro de válvula (5) na circunferência externa da manga de válvula (6). esta conexão fixa por compressão está caracterizada pelo fato de que, para cada dois destes componentes de metal (2, 5, 6, 44) da válvula de injeção de combustível, pelo menos, um dos parceiros de componentes, em sua área de compressão (a, b, c, a'), apresenta, pelo menos, duas zonas sucessivas e/ou zonas parciais (i, ii, iii) que apresentam uma estrutura com ranhuras (61), na qual a profundidade do perfil das ranhuras (61) diferencia-se nas zonas individuais e/ou parciais (i, ii, iii).
