Abstract

Patente do Invenção: "BOCAL DE INJEçãO". No caso de um bocal de injeção de combustível para um motor de combustão interna, com um corpo do bocal (10), uma agulha do bocal (12), a qual, dentro do corpo do bocal é deslocável entre uma posição fechada, na qual esta encosta em uma sede de vedação (16), e uma posição aberta, na qual esta, em direção ao espaço de combustão, é elevada da sede de vedação, uma câmara de pressão (24), a qual é ligada com uma alimentação de combustível (26), uma câmara de comando (42), a qual, comandada por uma válvula de comando (46), é ligada com a alimentação de combustível, e uma haste premente (40), a qual é ligada com a agulha do bocal e se projeta para dentro da câmara de comando, uma força de fechamento deve ser fornecida de maneira segura, a qual supera uma força de abertura, produzida na região da sede de vedação. Com este objetivo é previsto, que a haste premente é provida com um êmbolo de reposição (28), o qual fecha a câmara de pressão (24) no lado afastado da sede de vedação, que o diâmetro externo do êmbolo de reposição é maior que o diâmetro da sede de vedação (16), e que a superfície, a qual resulta da diferença entre a superfície de corte transversal do êmbolo de reposição (28) e da superfície envolvida pela sede de vedação (16), é menor que a superfície de corte transversal da haste premente.
