  • Patent number: 4945877
    Abstract: The fuel injection valve according to the invention enables an improvement in the fuel preparation and hence a more uniform fuel-air mixture while simultaneously supplying different inlet valves of an engine from one fuel injection valve. Downstream of the valve seat face of the fuel injection valve, the fuel enters a central opening from which tangential conduits lead to at least two swirl chambers disposedly spaced apart from one another and which discharge into these chambers at a tangent. From the center of each swirl chamber, which may be embodied in an attachment, a respective metering opening leads to the outside, by way of which fuel can be injected, well prepared, in the form of cone-shaped fuel streams. The fuel injection valve is suitable either for supplying individual inlet valves with a plurality of fuel streams, or for supplying different inlet valves of the engine with fuel at the same time.
