    摘要: A valve needle suitable for injection valves for fuel injection systems of internal combustion engines. The new valve needle includes a tubular actuation part, an armature section and a valve sleeve section and is manufactured by injection moulding and subsequent sintered according to a metal injection moulding method. Subsequently, the actuation part is connected to a valve closing element section by means of a weld connection such that the valve needle is manufactured in a simple and cost-effective manner.

    摘要: A fuel-injection valve having a metallic perforated disc arranged on a valve-seat body downstream of a valve-seat. The perforated disc arranged on the valve-seat body is supported by a supporting disc which is provided with a passage orifice and which is thicker than the perforated disc. This effectively prevents an undesirable bending of the perforated disc and at the same time improves the fuel treatment at the spray orifices. The supporting disc is made pot-shaped and is welded, together with the perforated disc, to the valve-seat body by a continuous welding seam. The fuel-injection valve is used in fuel-injection systems of mixture-compressing spark-ignition internal-combustion engines.

    摘要: An electromagnetically actuatable fuel injection valve which serves to supply fuel to a mixture-compressing internal combustion engine having externally supplied ignition. The fuel injection valve includes a valve housing with a mouth piece in which a valve seat body is disposed, two magnet coils two cores and one armature, which has a spherical guide section and is connected to a valve needle. The spherical guide section is slidably supported with its circumference in a guide bore of the valve seat body and in its stroke movement away from the core is limited by a tapering stop opening which adjoins the guide bore. A plastic bushing is mounted on a guide step of the valve seat body and is pressed by a spring against the core end face, thereby preventing a dirct flow of fuel to the remnant air gap on the armature, as a result of which the depositing of soil particles in the gap is avoided.

    摘要: In electromagnetically operable valves which have been proposed, having a fuel inlet connecting piece which is surrounded by a magnet coil and is used as a core, at least a part of the valve is surrounded by a plastic sheath on which an electrical connecting plug is integrally formed. However, different valve extrusion coating tools are required depending on the embodiment of the electrical connecting plug. In the valve, the electrical connecting plug (21) is injection moulded at the same time as the extrusion coating of the magnet coil (4) and thus forms an independent plastic injection molding. Only one valve extrusion coating tool is now required for different embodiments of the electrical connecting plug, resulting in greater flexibility in the assembly line. The valve is used as an injection valve for fuel injection systems.

    摘要: The invention relates to an electromagnetically actuatable fuel injection valve which is used to supply fuel to a mixture compressing internal combustion engine. The fuel injection valve comprises a valve housing provided with an extension in which a valve seat body is disposed. A magnetic coil is mounted on each of the pole parts and a permanent magnet is disposed between the poles of the pole parts. The valve seat body is connected to a guide via a collet. The guide, collet and valve seat body are penetrated by a valve needle which is connected at its one end to an armature and which, at its other end, ends in a closing end. In the guide is a guide bore which is adapted to radially guide a spherical head portion of the valve needle and which then tapers into an abutment face, against which face the valve needle rests by way of the head when the injection valve is open. To open the valve, the valve needle is moved outwardly, thereby uncovering an ejection opening between a valve seat and the closing head. The valve seat body and collet may be screwed together for the purpose of adjusting the valve stroke.
