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.

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： An electromagnetically actuatable valve is proposed which serves in particular to inject fuel into the intake tube of internal combustion engine operating with fuel injection systems. The fuel injection valve includes a valve housing, a shell core having a magnetic coil and a flat armature, which is positively connected to a valve element comprising a ball which protrudes through a central opening in a guide diaphragm to cooperate with a fixed valve seat. The guide diaphragm guides the ball in the radial direction relative to the valve seat. Under spring tension, the flat armature, having a guide crown, contacts the guide diaphragm and is thus guided in a plane parallel to the end face of the shell core. A first fuel fitting comprises a portion of a valve housing preshaped by a non-cutting manufacturing method; a second fuel fitting is fixed inside the first fuel fitting in such a manner that a flow conduit is defined between the first and the second fuel fittings. The fuel flowing in via the second fuel fitting proceeds to the valve seat; when the valve is open, a portion of the fuel is delivered there to a nozzle bore in order to be metered. The non-metered fuel flows around the magnetic element and proceeds via the flow conduit into a fuel return flow line.

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 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.
