    摘要: In valves having flat armatures, in order to attain the shortest possible switching times, the goal is to to reduce the mass of the armature and the surface area of the stops. A particularly advantageous design is obtained by embodying the flat armature in the manner of a gear wheel and providing at least three radially extending teeth, spaced uniformly apart from one another, on which the stop lobes that cooperate with a stop integral with the housing upon actuation of the valve by excitation of the magnetic coil are formed. A flat armature embodied in this way can be used in any correspondingly embodied valve.

    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.

    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, included are two magnet coils two cores and one armature, which has a spherical guide section and the later is being 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. Flat faces are provided on the circumference of the spherical guide section, such that they decrease the area of contact between the spherical contact section and the stop opening.

    摘要: A fuel injection system for internal combustion engines having a plurality of fuel injection valves of the top-feed type and a fuel distributor, which has a distributor duct formed in a plastic housing and connecting branches, each of which accepts an end-face supply connection of an injection valve. For simplified manufacture and assembly and in order to secure the injection valves against radial twist, electrical plug jacks are integrated in the plastic housing of the fuel distributor to accept corresponding electrical plug elements of the injection valves. Two of the plug jacks are associated in each case with one of the connecting branches in such a way that when the injection valve is pushed into the connecting branch the plug elements simultaneously penetrate into the associated plug jacks. All the plug jacks are electrically connected to a multi-pole connecting plug located on the fuel distributor, and the electronic control unit for controlling the injection valves is connected to the multi-pole connecting plug.

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.
