Abstract: A fuel injection device for internal combustion engines, having a fuel injection pump, which can be inserted into a housing of the engine and is axially clamped together with a fuel injection valve by means of a clamping sleeve. The valve, with an end remote from the pump, protrudes into a combustion chamber of the engine. A fuel supply line to the fuel injection pump feeds into an annular chamber encompassing the clamping sleeve and, via through openings in the clamping sleeve and inlet conduits in the pump housing, the valve can be connected to a pump working chamber of fuel injection pump. According to the invention, the fuel filter in the inlet to the pump working chamber is constituted by the clamping sleeve, which has a multitude of filter openings for this purpose in its circumference wall, in the vicinity of the annular chamber.

Abstract: 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.
