ABSTRACT:
A device for injecting fuel into the combustion chamber of an internal combustion engine including a high-pressure storage chamber, a pressure booster, and a metering valve. The pressure booster includes a work chamber and a control chamber separated from one another by an axially movable piston. A pressure change in the control chamber causes a pressure change in a compression chamber of the pressure booster. The compression chamber acts upon a nozzle chamber in the nozzle body. A pressure relief valve (40) is in a control line between the control chamber of the pressure booster and a 2/2-way metering valve, the pressure relief valve includes a valve body that acts upon at least one hydraulic chamber and can be made to communicate with the pressure prevailing in the high-pressure storage chamber.
