Kraftstoffeinspritzvorrichtung für eine Brennkraftmaschine

A mechanically pressurized electronic fuel injector (5) is for use in internal combustion engines and is actuated by the engine valve train. The fuel injector (5) has an injection stroke for discharging fuel into the engine and a metering stroke for receiving a predetermined volume of fuel in the injector (5). During the injection stroke, a coupling member (20) contacts a timing plunger (16) and transmits a compressive force from the engine valve train. The coupling member (20) and the timing plunger (16) are not mechanically connected together and are capable of independent relative movement. During the metering stroke of the injector (5), the timing plunger (16) is returned to its pre-injection position under the pressure generated by the fuel entering the timing and metering plunger chambers (26 and 33).
