Abstract
Injetor de combustível que abre para fora. Injetor de combustível (1) provido de: uma válvula (7) de injeção compreendendo um bico (3) de injeção; uma agulha (17) móvel para regular o fluxo de combustível através da válvula (7) de injeção e que termina com uma cabeça de fechamento (27), a qual engasta com um assento de válvula (18) da válvula (7) de injeção, e que é disposta externamente com relação à válvula (7) de injeção e que se apresenta com um diámetro pré-determinado de selagem; um atuador (6) para deslocar a agulha (17) entre uma posição fechada e uma posição aberta da válvula (7) de injeção; uma mola (10) de fechamento a qual tende a manter a agulha (17) na posição fechada da válvula (7) de injeção empurrando a cabeça de fechamento (27) contra o próprio assento de válvula (18) em um sentido contrário ao do sentido de alimentação de combustível; e um corpo (4) de suporte que tem um formato tubular e que apresenta um canal (5) de alimentação dentro do qual está disposta uma agulha (17), tem a agulha (17), em uma extremidade oposta da cabeça de fechamento (27), sendo acoplada a um canal (28) de balanceamento, o qual está à pressão ambiente.
