摘要： A method is proposed which serves to produce a valve needle of a needle valve. The basis of the method is the production, from a wire serving as the raw material, of a springlike coil on a carrier body, where the adjacent courses of the coil rest on one another, and this coil applied to the carrier body is provided on its circumference with a predetermined contour by grinding on a grinding machine. After the grinding, the individual courses of the coil, forming the individual valve needles, are separated. The wire serving as the raw material and the valve needles after separation of the courses of the coil can be subjected in a suitable manner to a heat treatment. In a simple and inexpensive manner, the method assures the production of curved valve needles with precise dimensions.

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： An electromagnetic valve consists of two valve housing parts, connected by crimping and axially braced, and having a magnetic pipe care therein. A flat armature is positively connected with a spherically shaped valve closing part, which extends through a central opening in a guide membrane for cooperation with a valve seat. The guide membrane rests via an outer circumference on a collar and is supported there via the axial tensioning force between the valve housing parts in assembled form. The guide membrane is welded to the collar on the outer circumference upon at least two points. Before the valve housing parts are combined, the guide membrane, abutting the collar, in concentrically guided into position by a centering body, having a slightly larger diameter than the valve closing part, on the valve seat and is welded at said points in this position. Thereupon the centering body is removed and the actual assembly of the valve is performed.

摘要： A fuel injection valve which serves to inject fuel into the intake tube of internal combustion engines. The fuel injection valve includes a valve housing, in which a nozzle body having a valve seat is firmly held. Downstream of the valve seat, the fuel is directed via metering fuel guide bores to a preparation bore, which is continued in the form of a preparation bore in an injection sheath. The injection sheath is held on the nozzle body by means of an adapter body surrounding and engaging the nozzle body, and it has an ejection segment within which the inside diameter of the preparation bore decreases in the flow direction toward the ejection end. Teeth are also provided on the ejection segment, pointing toward the ejection end.

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： A fuel injection valve and a method for the automatic establishment of the desired armature stroke of the fuel injection valve are proposed which serves the purpose of injection at low fuel pressures into the intake tube of a mixture-compressing internal combustion engine with externally-supplied ignition. The fuel injection valve includes a magnetic coil surrounding a core and a flat armature guided by at least one guide diaphragm held on its outer circumference, which is firmly connected with a movable valve element cooperating with a fixed valve seat. The fuel delivered via a fuel inlet nozzle can proceed through apertures and recesses in the guide diaphragms past the valve seat to a fuel discharge nozzle by way of which a portion of the delivered fuel can flow back again into a fuel return line. Via an annular channel the fuel stream exiting from the nozzle bore cab be prepared with air which surrounds the fuel stream.

摘要： An electromagnetic fuel injection valve and a process for the adjustment of the armature stroke (H) of the fuel injection valve is proposed, which serves to inject fuel under low pressure into the suction pipe of an internal combustion engine. The fuel injection valve surrounds an armature guided in a valve housing. This armature is tightly fastened to a movable valve section which cooperates with a fixed valve seat in a nozzle body supported in a nozzle carrier. The armature stroke can be adjusted in an assembled condition of the fuel injection valve by moving the nozzle body in an axial direction. For this the stroke (H.sub.eff) is measured by an odometrical system (distance sensing system), in the assembled condition of the fuel injection valve while the electromagnetic system is excited and the fixed valve seat provided on the nozzle body is displaced with the aid of a pressing tool by the difference between the measured stroke (H.sub.eff) and the desired armature stroke (H).
