Abstract
A nozzle needle (,) of a fuel injection valve is guided axially in a nozzle body (,), and it points with its rear end face (,) into a compression chamber (,) and is operatively connected to a damping body (,). The recesses (,) of the damping body (,), together with the damping bore (,), form a fuel-filled damping chamber (,). Upon valve opening, the fuel in the compression chamber is compressed, and thus the valve opening is delayed. If the nozzle needle exceeds the damping stroke (hd), then the fuel is depressurized by a communication with an outflow chamber (,). The damping body is guided over at least part of its length in the damping bore.
