Abstract

a presente invenção refere-se a um bico injetor (1) para combustível com um corpo do bico (2), no qual é formada uma câmara de compressão (4) que pode ser preenchida com combustível sob ele-vada pressão, na qual é disposta, móvel longitudinalmente, uma agu-lha do bico (3) em forma de pistão. em uma extremidade da agulha do bico (3) é formada uma superfície de vedação (6) e na extremidade oposta, é formada uma superfície frontal (9), sendo que, a superfície de vedação (6) atua em conjunto com o assento do bico (5) para o abrir e fechar de pelo menos uma abertura de injeção (8). uma câmara de controle (10) que pode ser preenchida com combustível sob pres-são alternada é limitada pela superfície frontal (9) da agulha do bico (3), de modo que, pela pressão hidráulica na superfície frontal (9), seja exercida uma força no sentido do assento do bico (5). a agulha do bico (3) apresenta uma seção longitudinal flexível (25) que apresenta uma rigidez longitudinal inferior a 40.000 n/mm.
