ABSTRACT:
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.
