    摘要: The nozzle plate according to the present invention includes an axial passage for a fluid, particularly for a fuel, which is made up in the downstream direction by a filter, a ring chamber and an uninterrupted ring gap following one another. Using this arrangement, a cohesive tulip-shaped jet lamella can be produced which thins out in the downstream direction and then disintegrates into tiny droplets. As a consequence, the exhaust emission of an internal combustion engine can be further reduced and likewise a reduction of the fuel consumption can be achieved. The nozzle plate is suited particularly for injection valves in fuel injection systems of internal combustion engines with externally supplied ignition which compress the mixture.

    摘要: An atomizer disk is composed of at least one metallic material, is configured with at least one inlet opening in an upper cover layer and at least one outlet opening in a lower base layer, and has at least two swirl channels that terminate into a swirl chamber, the swirl chamber being provided in a middle swirl generation layer. Through the inlet opening and the swirl channels, two flows of different natures (biflux) enter the swirl chamber. All the layers of the atomizer disk are built up directly onto one another by electroplating metal deposition (multilayer electroplating). The atomizer disk is suitable for use in a fuel injection valve, in particular a high-pressure injection valve for direct injection of fuel into a combustion chamber of a mixture-compressing, spark-ignited internal combustion engine.

    摘要: An electromagnetically operable valve includes at least one component part, e.g. the armature, which possesses, prior to the application of a wear resistant coating, a wedged surface, which is in each case variably creatable in accordance with a magnetic and hydraulic optimum. The annular impact segment formed by the wedging possesses a defined impact face width or contact width which remains constant throughout the service life, since any wearing of the impact face does not lead, in continuous running, to an enlargement of the contact. The valve is particularly suitable for use in fuel injection systems of explosion-type, spark-ignition combustion engines.

    摘要: A propelling nozzle has upper and lower primary and secondary flaps which are disposed opposite one another at a mutual distance and which are sealingly movably guided between lateral wall portions of a four-cornered nozzle housing. The primary flaps are arranged pivotally about a fixed axis of rotation on the nozzle housing. The secondary flaps, in each case upstream of levers non-rotatably connected with the primary flaps, are pivotally linked to pivots situated on the side facing away from the nozzle flow. The secondary flaps change into the primary flaps with a surface section which is bent concentrically with respect to the pivots. The primary and secondary flaps are arranged in a four-cornered nozzle housing which is itself closed in. In each case the secondary flaps are arranged on the nozzle housing in an axially movable and angularly adjustable manner at the downstream end. The levers are formed on interior sections which are bent away from the primary flaps in a toggle-lever-type manner. At the rearward ends of the levers, pivots are located. The levers have cutouts which are concentric with respect to the pivots. The surface sections of the secondary flaps can be moved into the cutouts. The upper and the lower primary and secondary flaps can be swivelled by means of their respective separate adjusting system. Each adjusting system is arranged between an upper or a lower wall portion of the nozzle housing and the flaps and, in the process, acts upon a primary or a secondary flap.
