Abstract
Patente de invenção: "DISPOSITIVO PARA A INJEçãO DE COMBUSTìVEL COM DECURSO DA PRESSãO DE INJEçãO VARIáVEL". Dispositivo para a injeção de combustível com um injetor (1) que contém um espaço de pressão (13). Do espaço de pressão (13) se estende uma tubulação de alta pressão (5) através de uma caixa de injetor (2) na qual é disposto um bocal (3) fechável por meio de uma agulha de bocal (4), sendo que a agulha de bocal (4) é solicitada por uma acumulador de força (7). São previstas válvulas de comando (8, 10), ajustáveis independentemente uma da outra e reguláveis mediante um elemento atuador (11) e unidas através de um espaço de acoplamento (9) uma à outra e com as quais pode ser regulado o decurso da pressão de combustível (24).
