In this new construction, the magnetic coil and the valve body have been moved to the bottom compared with injectors used up to now and are positioned directly above the nozzle needle. The long and sluggish pressure rod is no longer needed. In this way, quick gearshift times, also with solenoids, are possible. In addition, a spiral-shaped groove has been milled into the nozzle needle, resulting in an optimum injection jet of fuel when it leaves the injection nozzle. The following is seen in the cutaway of the injector: Injector housing with cap nut, nozzle body with nozzle needle, high-pressure canal, pressure spring, valve body, solenoid, fuel feed, edge-type filter and electrical connection.
