Abstract
The injection device for a direct-injection internal combustion engine has an actuator and a piston connected to the actuator. A compression chamber connects to a high-pressure line. The device further includes an injection nozzle, a nozzle spring chamber, a nozzle chamber, a fuel supply line, and a pressure-relief valve. The pressure-relief valve draws a constant volume of fuel from the high-pressure line when it closes.
