摘要： The invention relates to a system for injecting fuel into a combustion chamber of an internal combustion engine, having a fuel injector, which can be subjected to fuel at high pressure and which is actuatable via a metering valve, by which the pressure in an injection valve member control chamber or in a control line is controllable such that an injection valve member opens and closes for injecting fuel. The injection valve member control chamber can be evacuated via an outlet throttle device into a control line which has a smaller throttle cross section than an inlet throttle device, by way of which the injection valve member control chamber can be filled.

Provision is made for enlarging the cross section of the outlet cross section out of the differential chamber of the pressure chamber are provided. The fuel pressure during the injection can be varied. A pressure increase can be simply achieved.

摘要： A device for injecting fuel into a combustion chamber of an internal combustion engine, including an injector body which contains an injection valve element which can be actuated through pressurization/pressure relief of a control chamber by means of a control valve. A pressure booster having a piston unit that divides a working chamber from a control chamber of the pressure booster acts on a compression chamber that communicates with a nozzle chamber encompassing the injection valve element. A pressurization or pressure relief of the control chamber of the pressure booster occurs as a function of the stroke motion of the injection valve element.

摘要： A fuel injection apparatus for injecting fuel into the combustion chambers of an internal combustion engine includes a high pressure accumulator, a pressure booster, and a metering valve. The pressure booster includes a working chamber and a control chamber that are separated from each other by an axially movable piston. A pressure change in the control chamber produces a pressure change in a compression chamber that acts on a nozzle chamber via a fuel inlet. The nozzle chamber encampasses a nozzle needle. A nozzle spring chamber that acts on the injection valve element can be filled on the high-pressure side via a line that leads from the compression chamber and contains an inlet throttle restriction. On the outlet side, the nozzle spring chamber is connected to a chamber of the pressure booster via a line that contains an outlet throttle restriction.

摘要： A fuel injection system has a pressure step-up unit, disposed between a pressure storage chamber and a nozzle chamber, whose pressure chamber communicates with the nozzle chamber via a pressure line. A bypass line connected to the pressure storage chamber is also provided. The bypass line communicates directly with the pressure line. The bypass line can be used for pressure injection and is disposed parallel to the pressure chamber, so that the bypass line is open regardless of the motion and position of a displaceable piston element in the pressure step-up unit. This enhances the flexibility of injection.
