ABSTRACT:
An electromagnetically-controlled fuel injection valve (1) for i.c. engines includes a body (2) carrying an upper electromagnetic metering valve (10) which controls communication between a control chamber (9), to which the fuel is fed under pressure through an inlet hole (Z) to keep the associated injector needle (4) in the closed position, and a discharge hole (A) for controlling the opening of the needle (4). The solenoid valve (10) with the control chamber (9), the inlet hole (Z) and the discharge hole (A) are integrated in a single element forming a head (13) for the body (2) of the injection valve (1).
