摘要： The invention relates to a fuel injection valve which is characterized in that it comprises a turbulence disc (30) which is located downstream from a valve seat (15). Said turbulence disc is comprised of at least one metallic material and of at least two turbulence ducts (70) which flow into a turbulence chamber (69). All layers (60, 61, 62) of the turbulence disc are produced by means of electrodeposition (multilayer metallizing). Said layers are directly deposited on top of one another such that they adhere in a fixed manner. The turbulence disc (30) comprises a top layer (60) having a plurality of material areas (60') which are separated from one another by opening structures (65, 66). The turbulence disc (30) lies with the material areas (60') thereof on a valve seat body (9) which comprises the valve seat (15). The fuel injection valve is especially suited for directly injecting fuel into a combustion chamber of a compound compressed, spark injection internal combustion engine.

摘要： The invention relates to a fuel injection valve which is characterized in that it comprises a multilayer turbulence disc (30) located downstream from a valve seat (15) which is formed on a valve seat element (13). At least both of these components are installed in the direction of the inflowing side inside a through opening (10) of a valve seat support (9). The valve seat support (9) has a lower base area (17) which provides for a reduction in size of the cross-section of the through opening (10) located downstream from the valve seat (15). The fuel injection valve is especially suited for directly injecting fuel into a combustion chamber of a compound compressed, spark injection internal combustion engine.

摘要： The perforated disc of the invention is characterised in that it is designed to provide a full axial passage for a fluid consisting of inlet apertures (36), outlet apertures (38) and at least one channel (42) therebetween. The at least three functional planes (35, 37, 40) of the perforated disc (23) with a characteristic aperture structure (36, 38, 42) are made one on another by galvanic metallisation (multi-layer galvanics). A galvanically deposited layer of the perforated disc (23) can have one or more functional planes (35, 37, 40). The perforated disc is especially suitable for use as injection valves in fuel injection systems, paint nozzles, inhalers, ink jet printers or in freeze drying processes, for the injection of fluids, e.g. beverages, or for atomising medicaments.

摘要： The disclosed valve has an injector plate (23) arranged downstream of a valve seat (29). The injector plate (23) is characterised in that it has a plurality of narrow fuel discharge slots (40) that are arranged in a star shape in the radial direction but have no common contact point. This arrangement allows fuel to be finely sprayed without requiring additional energy. The breaking down into smallest droplets also results in a further reduction of the exhaust gas emission of an internal combustion engine and in a reduction of fuel consumption. This valve is particularly useful for fuel injection systems spark-ignited internal combustion engines with high compression ratio of the mixture.

摘要： The invention relates to a fuel injection valve comprising a moveable valve part (20) which co-operates with a fixed valve seat (27) for opening and closing the valve, said valve seat being formed on a valve seat element (26). An atomising disc (30) is arranged downstream from said valve seat (27). Said atomising disc (30) has a first downstream layer (58), into which fuel flows in a central manner and in which at least one radially extending opening region (61) is provided, through which fuel can flow in a radially outward direction, said opening region ending in an impact wall (63). A slit-shaped outlet (64) is transversally connected downstream from said impact wall (63), in a second downstream layer (59) of the atomising disc (30), by which means the fuel is spread and finely atomised. The inventive fuel injection valve is especially suitable for directly injecting fuel into a combustion chamber of a mixture-compressing, spark-ignition internal combustion engine.

摘要： The perforated disc of the invention is distinguished in that it provides a complete axial passage for a fluid, especially a fuel, formed by inlet apertures (36), outlet apertures (38) and at least one channel (42) therebetween. The inlet and outlet apertures (36, 38) are arranged in the perforated disc in such a way that they do not overlap on projection in a plane at any point. This staggering of the outlet apertures (38) in relation to the inlet apertures (36) provides an S-shaped flow fo the medium, to which is thus imparted a turbulence favouring atomisation. The perforated disc is especially suitable for use in injection valves in fuel injection systems, paint nozzles or freeze-drying processes.

摘要： In already known fuel injection valves, wearing parts such as the armature and the core are provided with wear-resistant layers made for example of chromium, molybdenum or nickel. If the parts of the injection valve are galvanically coated, a desired wedge-shaped distribution of the layer thicknesses is achieved that creates only a small bearing area but which is physically predetermined and practically impossible to influence. The new valve has at least one part, for example the armature (27) that has a stepped surface before the wear-resistant layer is applied. The stepped surface may be produced in a variable manner depending on the desired optimum magnetic and hydraulic properties. The ring-shaped bearing section (69) formed by the step has a defined bearing surface or contact width (b) that remains constant during the whole service life of the part, as wearing of the bearing surface in continuous duty does not cause the contact width to increase. This valve is particularly suitable for use in fuel injection systems of mixture compressing, spark-ignited internal combustion engines.
