Fuel injection system

The device has an injector (3') and a solenoid valve (8) to control the injection process. The valve interior has a first flow channel to feed fuel through an anchor chamber (16) and at least one second flow channel to return the fuel towards an aperture. The second channel is connected to a fuel return into a fuel tank. The fuel return is located in the injector housing (3). The solenoid valve is positioned at an angle of 90 degrees relative to the injector housing. There is an upper and a lower channel for fuel flow return (S3,4). An injector leakage tube (17) is connected to one of the valve flow channels.
