ABSTRACT:
In a fuel injector for direct fuel injection into a cylinder of an internal combustion engine under the control of an electromagnetic valve, wherein an injector housing has a control piston and a valve body disposed in a cylindrical opening formed therein whereby the high pressure fuel supply to a nozzle valve at one end of the injector is controlled, the valve body forms a valve whose downstream end is in communication, by way of a throttle structure, with a low pressure fuel return line through whichfuel under pressure can be released, the discharge of fuel from the downstream end of the valve body to the return line being further controlled such that fuel can be discharged to the fuel return line only when the nozzle valve is closed.
