    摘要： In an injection valve, a perforated disk made from a material of relatively great hardness. The perforated disk has a tensile strength of >800N/mm.sup.2. Spray holes are punched from a downstream side of the perforated disk to an upstream side. A stamping break-out, which occurs due to the greater brittleness of the material, has no negative effects since the perforated disk is installed in the injection valve such that the direction of flow of the medium is exactly opposite to the punching direction. The injection valve is particularly suitable for fuel injection systems of mixture-compressing applied ignition internal combustion engines.

    摘要： When an internal combustion engine is hot, especially in hot starting or during hot idling, outgassing of fuel occurs upstream of the injection port disk and at the injection ports; as a result, because too little fuel is supplied, the running performance is undesirably impaired. The running performance of the engine is therefore intended to be improved by preventing the development of vapor bubbles. By the provision of a transfer element, in the form of a raised body shoulder formed on the valve seat body, that reduces the heat transfer between the valve seat body and the injection port disk, it is accomplished that the injection port disk cools down as a result of the extracted heat of evaporation of the injected fuel, and thus the danger of vapor bubble development at the injection ports or upstream is reduced. The fuel injection valve is especially suitable for fuel injection systems in mixture-compressing internal combustion engines with externally supplied ignition.

    摘要： A perforated-disk carrier is provided on the fuel injection valve downstream of the valve seat surface, the perforated-disk carrier having an inner, dish-shaped carrier section into which a multiplicity of perforated disks with different dimensions can be inserted. To achieve this end, the cupshaped perforated-disk carrier rests partially against the lower end of the valve seat body exhibiting the valve seat surface and is rigidly connected to the body. In the installed condition, the perforated disk, which is selected in accordance with the corresponding requirements and is inserted in the carrier section, likewise rests against the lower end of the valve seat body. The fuel injection valve is particularly suitable for fuel injection systems of mixture- compressing, applied-ignition internal combustion engines.
