Abstract

Patente de Invenção: "BOCAL INJETOR". Em um bocal injetor de combustível com um corpo de bocal (12), que apresenta um primeiro e um segundo grupo de furos de injeção (14, 16), uma primeira e uma segunda agulha de bocal (18, 20) bem como um câmara de pressão (24, 34) separada para cada agulha de bocal, de modo que estas, independentemente entre si, são deslocáveis entre uma posição fechada, em que os furos de injeção associados à correspondente agulha de bocal estão fechados, e uma posição de injeção, em que os correspondentes furos de injeção estão abertos, deve ser possível com uma estrutura simples uma livre seleção das seções transversais de injeção. Para essa finalidade é previsto que as duas agulhas de bocal sejam contíguas entre si.
