Abstract (en)

[origin: US2008093484A1] An injection nozzle for an internal combustion engine, in particular in a motor vehicle, the nozzle including a nozzle body having at least one injection port, a nozzle needle supported to execute a stroke inside the nozzle body to control an injection of fuel through the at least one injection port, a booster piston that is drive-coupled to an actuator and having a booster surface, the nozzle needle or a needle unit including the nozzle needle having a control surface that is hydraulically coupled to the booster surface. A bypass piston is supported to execute a stroke inside the booster piston, the bypass piston having a bypass surface that is hydraulically coupled to the booster surface, the bypass piston resting against a stop that is stationary in relation to the nozzle body, in an initial state in which the nozzle needle closes the at least one injection port, and the bypass piston having a reservoir surface that delimits a reservoir provided inside the booster piston.
