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： An electromagnetically actuatable fuel injection valve which has an internal scavenging system for cleaning dirt particles from a magnetic field air gap. A portion of the fuel flowing in via an inflow line and an inflow opening reaches the vicinity of an air gap defined on one side by an armature and on the other by magnetic poles and flows through this gap, and then flows via an outflow opening to enter an outflow line that communicates with a fuel return. As a result of the described scavenging of the air gap, dirt particles are prevented from becoming firmly attached there and causing impairment of the performance of the fuel injection valve.

摘要： A temperature-dependent resistor or hot wire is extended over at least three anchoring points and to improve the measuring accuracy of the hot wire and to ensure sufficiently high temperatures over the entire active length of the hot wire during a cleaning step by burning, the hot wire is configured in the shape of loops at all anchoring points and the intersecting wire sections of the loops are conductively connected with one another. Current lead wires are preferably conductively attached to the hot wire by means of which the current is conducted to an electric control device. The end anchoring points are preferably electrically heated during an interruption of the measuring process of the hot wire and the hot wire may be directed in a W-shape over anchoring points whereat the hot wire is connected to the electric current, during the measuring process, via the two central, symmetrical anchoring points and upon an interruption of the measuring process, by means of a switching device, via the two end anchoring points.

摘要： A fuel injection system for internal combustion engines is proposed which serves the purpose of fuel injection into the air intake tube of the engine. The fuel injection system includes a fuel injection valve, which is supported upstream of a throttle valve in a holder body disposed coaxially in the air intake tube. A fuel supply line leads to the fuel injection valve, extending in a downwardly directed manner toward the fuel injection valve and away from a deaeration chamber. A fuel return line leads away from the fuel injection valve, extending in an upwardly inclined direction to discharge into the regulating chamber, disposed at a higher level, of a pressure regulating valve. A fuel feed line originating at a fuel supply pump terminates in an upwardly directed manner into the dearation chamber, which communicates via a dearation nozzle with the regulating chamber, so that vapor bubbles can escape upstream of the injection valve into the return side of the injection valve.

摘要： A fuel injection system for injecting fuel into the air intake tube of an internal combustion engine, including at least one fuel injection valve, which is disposed in a holder body and communicates with a fuel supply line and a fuel outflow line. The fuel injection valve is provided with a fuel supply groove, branching off from which are fuel inlet openings, and a fuel outflow groove, leading away from which are fuel outlet openings. The fuel injection valve is guided in the radial direction in a guide opening of the holder body by supporting bodies of a fuel filter which extends axially over the fuel injection valve, covering the fuel supply groove and the fuel outflow groove. The middle supporting body of the fuel filter is embodied such that it seals off the fuel supply line and the fuel supply groove from the fuel outflow line and the fuel outflow groove. In order to carry away vapor bubbles, there is either a degassing conduit embodied on the fuel injection valve between the fuel supply groove and the fuel outflow groove, a degassing conduit embodied on the middle supporting point, or a degassing conduit embodied on the holder body.

摘要： An electromagnetically actuatable valve, in particular a fuel injection valve for fuel injection systems, which serves to supply fuel to internal combustion engines. The fuel injection valve comprises a valve chamber and a core upon which a magnet coil is wound by use of a carrier body. A flat armature is constructed in such a manner at its side facing core that it partially overlaps the front surface of a ferromagnetic valve chamber with its outer range of action so that the magnet circuit is guided to the flat armature via valve chamber and the front face and so that magnetic coil, when actuated, simultaneously serves as a detent for the flat armature.
