摘要： An electromagnetically actuatable valve is proposed, which serves in particular to inject into the intake tube a mixture-compressing internal combustion engines with externally-supplied ignition. The valve includes a flat armature which is firmly connected with a ball arranged to cooperate with a fixed valve seat. The flat armature is pivotably supported on its end remote from the valve seat on a spring tongue preferably embodied out of a remnant air disc. A tubular inflow stub is disposed concentrically to the valve axis, communicating on one end with a fuel distributor line and on the other end protruding as deeply as possible into the valve. A tubular outlet stub leading away from the valve seat is concentrically guided in the inlet stub, and arranged to have its end remote from the valve seat discharge into a fuel return flow line. As a result, a cooling of the valve and the return of heated fuel which contains vapor bubbles to its supply source is assured.

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： 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 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.

摘要： The invention relates to an electromagnetically actuatable valve, which serves in particular to inject fuel into the intake tube of mixture-compressing internal combustion engines having externally supplied ignition. The valve includes a flat armature which is firmly connected with a movable valve member which cooperates with a fixed valve seat and embodied as a ball element. The flat armature is pivotably supported on its side remote from the valve seat or on the side oriented toward the valve seat on a spring tongue preferably embodied out of a remnant air disc. The one-sided fixation of the flat armature on the spring tongue assures an unequivocal up-or-down movement of the flat armature.

摘要： An injection valve for fuel injection systems in internal combustion engines which comprises a movable valve element cooperating with a valve seat disposed in a nozzle body, with a guide bore provided downstream of the valve seat. A swirl insert is partially compressed in the guide bore and disposes open swirl channels in the direction of its circumference. The swirl channels extend in an axial direction from one end of the swirl insert to the other, are slanted toward the longitudinal shaft of the injection valve and discharge in a tangential direction into a preparation bore. The swirl channels serve simultaneously as metering channels whose throttling length is adjustable by displacing the swirl insert inside the guide bore.

摘要： An assembling device for assembling and disassembling a fuel injector in a mounting hole of a cylinder head of an internal combustion engine has a jacket body at least partially surrounding the fuel injector. A contact section, on which both a hold-down force for holding down the fuel injector in the mounting hole and a disassembling force for disassembling the fuel injector can be exerted on the fuel injector, and a collar section protruding from the mounting hole are formed on the jacket body. The collar section has at least one thread, in which a disassembling screw can be screwed in so that when the disassembling screw is tightened it abuts on the cylinder head and transmits a disassembling force on the collar section so that the assembling device (1) with the fuel injector (3) inserted into the assembling device (1) is extracted.
