Abstract

"INJETOR DE COMBUSTìVEL COM COMANDO DE AGULHA DIRETA". A presente invenção refere-se a um injetor de combustível para motores de combustão com um reservatório de alta pressão de combustível (5), uma unidade de multiplicação de pressão (8) e um componente de válvula injetora (10), apresentando ao menos um segmento de unidade de multiplicação (11) e ao menos um segmento de agulha (13) que fecha uma abertura de injeção (16). A unidade de multiplicação de pressão (8) está integrada em um alojamento de unidade de multiplicação (9) e apóia-se em um elemento molar (27) que envolve o alojamento na unidade de multiplicação (9). Desta maneira o alojamento da unidade de multiplicação (9) é retida em um componente de alojamento de pico (15) que envolve o componente da válvula injetora (10).
