Abstract

Patente de Invenção: "PROCESSO E DISPOSITIVO PARA A CONFIGURAçãO DO DECURSO DA PRESSãO DE INJEçãO EM INJETORES". A invenção refere-se a um processo para a configuração do decurso da pressão de injeção (27) em injetores, os quais são empregados, por exemplo, em dispositivos de injeção de sistemas de injeção em veículos automóveis. O dispositivo de injeção compreende uma parte de bombeamento (1) assim como uma parte do bocal de injeção (2). A parte de bombeamento (1) e parte do bocal de injeção (2) ficam em conexão uma com a outra por meio de uma tubulação de alta pressão (3). Na parte de bombeamento (1) são contidas válvulas de comando (8, 10), as quais são excitadas por meio de um atuador (9). Através da excitação por meio do atuador (9), parâmetros de injeção são determinados durante a fase da injeção prévia (28), a fase do estabelecimento da pressão (29) e durante a fase da injeção principal (30).
