Abstract
A fuel injection valve for internal combustion engines, having a housing () in which a pistonlike valve member () is disposed longitudinally displaceably in a bore (). The valve member () is surrounded, over at least part of its length, by a pressure chamber (), embodied in the housing (), that can be filled with fuel at high pressure; the valve member () controls the communication of the pressure chamber () with at least one injection opening (). The pressure chamber () communicates with a damping chamber (), embodied in the housing (), via at least one throttle () disposed in the housing (), so that pressure fluctuations that occur in the damping chamber () rapidly fade (FIG.).
