Abstract

Patente de Invenção: <B>"INJETOR DE COMBUSTìVEL FLUIDO PARA MOTOR à COMBUSTãO INTERNA"<D>. A invenção refere-se ao injetor em uma câmara de combustão de motor de ignição comandada compreende um corpo de injetor (10) contendo uma agulha (12) terminada por um elemento de obturação que coopera com uma sede de passagem do combustível prolongada por um orifício de difusão. A agulha é deslocável axialmente entre uma primeira posição axial, na qual o elemento de obturação se apóia sobre a sede, e uma segunda posição na qual o elemento de obturação fica afastado da sede. Ele compreende, além disso, um elemento monobloco (28) fixado na parte a jusante do corpo (10), no qual são dispostos a sede, o orifício de difusão e uma perfuração de orientação deslizante da agulha, esse elemento tendo uma forma de diaboló para definir com essa parte a jusante do corpo uma câmara de fornecimento de combustível que apresenta perfurações que fazem com que a câmara se comunique com essa perfuração, imediatamente a montante da sede e desembocando tangencialmente na perfuração, e passagens de alimentação da câmara.
