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 can be prepared with air which surrounds the fuel stream.

摘要： A fuel injection system for internal combustion engines having a multiplicity of injection valves which serves to provide fuel supply is proposed. The fuel injection system includes a common, rigid fuel line, having plug nipples into which the injection valves associated with the individual cylinders of the engine can be inserted in a sealing manner. The fuel line comprises one fuel distributor line and one fuel return flow line located one above the other. Each injection valve has one inlet stub and one outlet stub disposed concentrically relative to one another, protruding into the plug nipple in such a manner that the inflow stub communicates with the fuel distributor line and the outflow stub communicates with the fuel return flow line. As a result, not only is it possible to provide simple sealing toward the outside between the injection valve and the plug nipple but also rapid assembly of the fuel injection system is assured.

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 fuel injection valve is proposed which, especially in low-fuel-pressure systems, serves to inject fuel into the intake tube of a mixture-compressing internal combustion engine with externally supplied ignition. The fuel injection valve includes a fixed valve seat cooperating with a movable valve element, downstream of which the fuel to be injected is carried into a mixture guidance channel of a mixture guidance tube and surrounded on all sides with air or exhaust gas for preparation immediately upon its entrance into the mixture guidance channel and injected via an injection opening into the intake tube. The mixture guidance channel may be embodied as tapering in conical fashion toward the injection opening. For the purpose of preliminary preparation of the fuel, secondary air or exhaust gas can already be delivered to the fuel before its entrance into the mixture guidance channel. The fuel injection valve embodied according to the invention assures optimal preparation of the fuel to be injected, even at low fuel pressures, and good running behavior of the engine in the event of abrupt changes in load.
