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： 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 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： An electromagnetically actuatable valve which serves in particular to inject fuel into the intake tube of internal combustion engines operating with fuel injection systems. The fuel injection valve includes a valve housing, a shell core having a magnetic winding and a flat armature, which is firmly connected with a valve element which passes through a central guide opening in a guide diaphragm and cooperates with a fixed valve seat. The guide diaphragm has a fastening zone and together with the central guide opening cut out of a centering zone of the guide diaphragm guides the valve element in the radial direction toward the valve seat. The fastening zone is connected via struts with an annular guide zone on which the flat armature, under spring tension, rests with a concentric guide edge and is guided in a plane parallel to the end face of the shell core. The centering zone of the guide diaphragm is connected in turn via struts with the guide zone.

摘要： An electromagnetically actuatable valve which serves in particular to inject fuel into the intake tube of internal combustion engines operating with fuel injection. The fuel injection valve includes a valve housing, a shell core with a magnetic winding, and a flat armature which is firmly connected to a valve element having a tubular section and a spherical section. A guide diaphragm attached to the housing engages a guide edge of the flat armature in an elastic manner and guides the flat armature parallel to the end face of the shell core. The coaxial guidance of the spherical section relative to the valve seat is effected by means of guide faces of a guide ring. As a result, the movable valve element can have an elongated embodiment, and the fuel injection can be effected at any desired location of the intake tube, while the valve simultaneously requires little installation space.

摘要： An electromagnetically actuatable valve, especially an injection valve for fuel injection systems which supply internal combustion engines with fuel, is proposed in which the fuel injection valve encompasses a valve chamber and a core upon which a magnetic coil is mounted by means of a carrier body. Fuel supply openings discharge into a flow passage provided around the magnetic coil. Vapor bubbles dissolved in the fuel may be flushed out of the flow passage via a first restriction into fuel return openings which communicate with a fuel return line. On the other hand, the fuel may flow from the flow passage into the collecting chamber which houses a valve component and a valve seat. Vapor bubbles which may appear near the valve component may be flushed out via a second restriction which is provided in the interior of a core to reach the fuel return openings. Thus, disturbances with fuel injection, especially during the "hot start" of the internal combustion engine, are avoided.
