    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 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.

    摘要： A fuel injection system for internal combustion systems is proposed, which serves to inject fuel into the intake tube of the engine. The fuel injection system includes at least one fuel injection valve which is disposed in the interior of a holder and communicates with both a fuel supply line and a fuel drainage line. The inflow of fuel into the fuel injection valve takes place radially via an inflow region. An orifice body is secured in the holder, forming a reservoir preceding the inflow region. In the first few seconds after hot starting of the engine, only the fuel stored in the reservoir reaches the inflow region and hence is injected. Because readily volatile fuel components have evaporated beforehand, the fuel stored in the reservoir enables especially good fuel preparation.

    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 supply line, which serves to supply fuel to a fuel injection system for internal combustion engines. The fuel supply line includes receptacles, in each of which a stepped receiving bore is formed with the bores arranged to surround the injection valve in the axial direction and open both at the mouthpiece and the connection end of the injection valve. The injection valve is held by a holding body with a holding shoulder of the injection valve resting on a holding step of the receiving bore. The receiving bore of the receptacle extends outside the flowthrough cross section of the fuel supply line. A filter element is provided in the flow path of the fuel between the flowthrough cross section and fuel openings at the circumference of the injection valve. The fuel supply line, together with the receptacles, is advantageously manufactured of plastic as an extruded part.

    摘要： An electromagnetically actuatable valve is proposed, which serves in particular to inject fuel into the intake tube of internal combustion engines having fuel injection systems. The fuel injection valve includes a valve housing, a core having a magnetic coil and an armature, which is guided by a guide diaphragm and is firmly connected to a bearing tube. Protruding into the bearing tube is a spherical pivot segment of a valve member, which is on the one hand partially surrounded and engaged by a pan-shaped segment of the bearing tube and on the other hand is axially fixed by means of a retainer ring. Joined to the pivot segment is an elongation segment, on the other end of which a spherical sealing segment is secured, and which is further radially guided by means of a guide ring and thereby cooperates with a valve seat in a nozzle body. Since the pivot segment is pivotably supported in the bearing tube, shear forces at the armature have no effect on the sealing segment.
