Abstract: A micromechanical device for measuring a pressure variable and a method for manufacturing a micromechanical pressure sensor. The sensor includes, two components; a first component featuring a diaphragm made of a first material, and a second component of a second material. This second component is designed to have a thin first region and a thick second region. The first and second components are permanently joined together via the first diaphragm and at least a portion of the first region. The materials are selected such that the temperature expansion coefficient of the first material is higher than that of the second material. The first and second components are joined in such a manner that a lateral expansion of the first diaphragm caused by temperature changes is transferred to the first region of the second component as a lateral expansion as well.

Abstract: A method for manufacturing a micromechanical pressure sensor and a pressure sensor manufactured using this method. The pressure is measured in the pressure sensor composed of at least two components via a capacitance measurement of a capacitor, the pressure sensor having at least one first electrode and one first diaphragm. The movement of the diaphragm causes a change in the capacitance of the capacitor which may be used in the capacitance measurement as a measure for the pressure variable to be measured. It is important that, prior to assembly, the first and the second components of the pressure sensor be processed separately. The first component has at least one semiconductor material and the first electrode, whereas the second component is made of metal, at least in part, and contains at least the first diaphragm.

Abstract: A method for manufacturing an orifice plate that is built up in multiple layers and includes a complete axial through passage for a fluid. The orifice plate includes inlet openings, outlet openings, and at least one conduit lying between them. The layers or functional planes of the orifice plate are built up on one another by electroplating metal deposition (multilayer electroplating). Orifice plates manufactured in this manner are particularly suitable for use on injection valves in fuel injection systems, in paint nozzles, inhalers, or inkjet printers, or in freeze-drying processes, for spraying or injecting fluids such as beverages.

Abstract: An orifice plate includes a complete axial through passage for a fluid, in particular for a fuel, including inlet openings, outlet openings, and at least one conduit located between them. The inlet and outlet openings are arranged in the orifice plate so that they do not overlap at any point when projected into one plane. This offset of the outlet openings with respect to the inlet openings results in an S-shaped flow profile for the medium, onto which an atomization-promoting turbulence is thus imposed. The orifice plate is particularly suitable for use on injection valves in fuel injection systems, in paint nozzles, or for freeze-drying processes.

Abstract: In a method for manufacturing a nozzle plate, two parts of the nozzle plate are fabricated separately from one another. The fabrication of the two parts is carried out by microstructuring/lithography, electroforming and plastic molding. Advantageously, a filter structure is provided in the first part. The two parts are joined together by means of laser welding, diffusion soldering or a chemical joining process. The nozzle plate is particularly well suited for injection valves, atomization nozzles, paint spray nozzles or other spraying systems.

Abstract: The valve in accordance with the present invention possesses a nozzle plate, which is distinguished by a plurality of narrow slots being provided in it as outlets for fuel. These slots are arranged running radially in a star shape, the individual slots not having a common point of contact. A uniform, very fine atomization of the fuel is possible with this arrangement without additional energy. A consequence of disintegrating into very small droplets is that the exhaust emission of an internal combustion engine can be further reduced and a reduction in fuel consumption can also be achieved. The valve is suited particularly for use in fuel injector systems of mixture-compressing internal combustion engines having externally supplied ignition.

Abstract: An orifice plate includes a complex axial through passage for a fluid is created, composed of inlet openings, outlet openings, and at least one conduit located between them. The at least three functional planes of the orifice plate, each with a characteristic opening structure, are built up on one another by electroplating metal deposition (multilayer electroplating) . A layer of the orifice plate deposited by electroplating can have one or more functional planes. The orifice plate is particularly suitable for use on injection valves in fuel injection systems, in paint nozzles, inhalers, inkjet printers, for freeze-drying processes, for spraying or injecting liquids, for example beverages, or for atomizing medications.

Abstract: A fuel injection valve has downstream a valve seat (23), an injector plate (23), which is characterized by having a plurality of swirl-producing elements on the intake side, followed by at least one uninterrupted annular gap in the downstream direction. The swirl-producing elements are arranged in a turbine vane-shaped form by each individual element running mostly radially and being tilted in the peripheral direction and the elements being arranged behind one another in a circular shape. The annular gap (45) represents the spray geometry. With this arrangement the fuel can be finely atomized without additional power consumption. The breakup into minute droplets results in further reduction of the exhaust emissions of an internal combustion engine and in lower if fuel consumption. The fuel injection valve is especially well-suited for use in injection systems of mixture-compression externally ignited internal combustion engines.
