Abstract

La valvola dell'invenzione comprende un organo otturatore (7) atto a controllare il passaggio del carburante attraverso un foro di iniezione (9) sotto il comando di un elettromagnete (2); tale organo otturatore è delimitato da una superficie laterale cilindrica (11) che è accoppiata a scorrimento con una corrispondente superficie cilindrica di guida (6) di una sede ricavata sul corpo (1) della valvola; in base all'innovazione, il baricentro (4) dell'organo otturatore (7) si trova in una sezione (SG)della valvola ortogonale all'asse della valvola stessa la cui distanza (d) dalla sezione media (Sm) della superficie cilindrica di guida (6) è inferiore a 2 mm.
