摘要： A fuel injection valve for fuel injection systems of internal combustion engines includes a core which serves as the internal pole is made of a soft magnetic powder composite material. This powder composite material is an iron powder provided with a polymer additive, where the individual iron particles are coated with an electrically insulating layer. Such a powder composite material ensures a substantial minimization of eddy currents in the magnetic circuit in comparison with materials known previously, such as chromium steel, which are usually used as magnetic materials. The core which is mechanically sensitive and is sensitive to fuel is encapsulated at least with respect to the parts of the injection valve carrying the fuel. A sleeve passes through an internal longitudinal opening in the core which permits fuel flow in its interior and is fixedly attached to a pole part which seals the core toward the bottom. The core and the magnetic coil are thus not exposed to any wetting by fuel. This fuel injection valve is especially suitable for use in fuel injection systems of internal combustion engines with mixture compression and external ignition.

摘要： A fuel injection valve for internal combustion engines with an injection port disk disposed in a longitudinal opening of a valve housing, which prevents deposits from forming due to evaporation of the fuel remaining at the injection ports after the engine is switched off. A gap disk is therefore disposed downstream of the injection port disk in the longitudinal opening of the valve housing with a slight axial spacing; the gap disk defines a recess in the axial direction which exerts a capillary action outward in the radial direction upon the fuel emerging at the injection ports. By disposing a capillary disk between the injection port disk and the gap disk, the capillary action can be optimized by means of corresponding contours in the capillary disk. The fuel injection valve is particularly suited for fuel injection in mixture-compressing engines with externally supplied ignition.

摘要： A fuel injector for fuel ignition systems of internal combustion engines includes a magnetic circuit having a core, a magnetic coil and an armature, and a movable valve needle, which has a valve-closure member that cooperates with a fixed valve seat, the valve seat being shaped on a valve-seat member and being provided with a valve-seat support in which the valve-seat member is inserted. At least one metallic component of the fuel injector, in this context, has a serrated structure on its outer circumference for producing a solid connection to a corresponding component made of plastic. The plastic components may be the connection piece, the valve-seat support, the coil shell and the connecting pipe of the valve needle. The fuel injector is particularly suitable for use in fuel-injection systems of mixture-compressing internal combustion engines having externally supplied ignition.

摘要： A method for manufacturing a solid housing, in particular a valve housing for an electromagnetically operable valve. The method includes providing at least three flat metal plates side by side, each having different magnetic properties directly adjacent to the others. The at least three plates are joined to the directly adjacent bordering edges to form a sheet metal section. The sheet metal section shaped into a sleeve shape. Furthermore, the bordering edges, which are now opposite one another, and run in the longitudinal direction of the sleeve to form a sleeve blank are joined together. The sleeve blank is machined until a desired geometric shape of the housing is achieved. The housing may be suitable in particular for use in fuel injectors in fuel injector systems of internal combustion engines operating by spark ignition of a compressed fuel-air mixture.

摘要： An electromagnetically actuatable valve, e.g., a fuel injector for fuel injection systems, includes an electromagnetic actuating element having a solenoid, a fixed core, a valve jacket, and a movable armature for actuating a valve closing body, which cooperates with a valve seat surface provided on a valve seat body. In addition, the valve has a restoring spring for resetting the valve closing body to its resting position on the valve seat surface. The restoring spring and an internal longitudinal bore hole of the armature are paired in such a way that the armature is guided during its axial movement only along the restoring spring.

摘要： A fuel injection valve having an energizable actuation device and having a valve member, movable by the actuation device, that is joined to a valve closure element. The valve closure element cooperates with a valve seat surface in order to open and close the valve. Arranged downstream from the valve seat surface is an orifice disk that is configured, with a bottom part and a retaining rim projecting out therefrom, in cup- or pot-shaped fashion. The thin orifice disk made of sheet metal has, in the transition region of the bottom part to the retaining rim, protrusions which enhance the rigidity of the orifice disk. The fuel injection valve is suitable in particular for fuel injection systems of mixture-compressing spark-ignited internal combustion engines.
