Abstract

Patente de Invenção: "CONJUNTO INJETOR COM UM ATIVADOR PARA O COMANDO DA SEQuêNCIA DA AGULHA". A invenção refere-se a um conjunto injetor de combustível altamente pressurizado em um motor de combustão. Um injetor (25) abrange um compartimento pressurizado (1), a partir do qual uma linha de alta pressão (3) desemboca em uma câmara de comando (4) de uma agulha de bocal (5). Além disso, no injetor (25) estão integradas duas válvulas de comando (11, 12), unidos, no lado do escoamento, com regiões (9) de nível de pressão mais reduzido. Uma das válvulas de comando (11, 12) que forma a seq³ência da injeção (20), contém um sistema de compensação de pressão (34), com o que a seq³ência da pressão de injeção (20) pode ser variada pela modificação da seq³ência do curso (23)da agulha de bocal (5).
