    Abstract: The invention relates to a fuel injection valve (1), in particular, for directly injecting fuel into a combustion chamber of an internal combustion engine. Said fuel injection valve comprises a valve closing body (4) that, together with a valve seating (6), which is provided on a valve seat body (5), forms a tight seat. The fuel injection valve also comprises a swirl plate (34) with fuel passages (35), whereby the swirl plate (34) is made of several swirl elements (36), and the swirl elements (36) each have the same number of fuel passages (35). The swirl elements (36) are offset from one another in such a manner that the fuel passages (35) at least partially overlap.

    Abstract: Fuel injection valves with venturi filters (50) for supplying fuel or fuel/gas mixtures to internal combustion engines are characterised in that they ensure a particularly high spray quality and remarkable fuel conditioning. In addition, the venturi filter (50) forms a protection screen against icing, plugging and deposits of chemical substances inside the fuel injection valve. The venturi filter (50), which has a shell-shaped, concave bulging form, is mounted downstream of at least one injection hole (15), seen in the fuel flow direction. The outer circumferential area (60) of the venturi filter (50) is cast into the protective cap (40) provided at the downstream end of the fuel injection valve. The protective cap (40) has protective teeth (62) that extend further downstream than the deepest area (56) of the venturi filter (50), in order to protect it against mechanical influences. When fuel is injected, a partial amount of fuel gathers in said deepest area (56) and forms a relatively still amount of liquid, to which new fuel is added. This arrangement allows ideal spraying of fuel in smallest droplets.
