摘要： A fuel supply line for use with fuel injection devices of internal combustion engines is proposed, having supports to contain fuel injection valves. The fuel supply line has an elastic wall section, with which is connected a rigid wall section and on which are fastened the supports. The elastic wall section is elastic to the extent that it damps the pressure pulsations of the fuel in the fuel supply line, whereas the rigid wall section assures the required rigidity of the fuel supply line.

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, two magnet coils two cores and one armature, which has a spherical guide section and is 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. A plastic bushing is mounted on a guide step of the valve seat body and is pressed by a spring against the core end face, thereby preventing a dirct flow of fuel to the remnant air gap on the armature, as a result of which the depositing of soil particles in the gap is avoided.

摘要： A magnetic injection valve for injecting fuel into the intake tract of internal combustion machines, which is distinguished by particularly good internal cooling. A magnetic coil wound onto a coil carrier is located in the valve, being introduced into a valve housing and surrounds a ferromagnetic core. The core acts upon an armature which is connected to a movable valve needle. A bushing in the core and a sleeve located outside the core are arranged such that the fuel, emerging from an inflow tract of a supply device flows via the sleeve serving as a fuel line and reaches the interior of the valve housing that receives the magnetic coil; after flowing virtually completely around the magnetic coil, the fuel leaves this interior via a bore and flows back between the bushing and the core as far as the end of the bushing, and then flows on through the bushing to reach the armature to flow on to the valve seat. For better cooling of the magnetic coil, flow conduits are machined into the coil holder such that the fuel flow virtually surrounds the coil.

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： A method for preventing damage to a temperature-dependent resistor disposed in a flow cross-section caused by overheating as a result of the ignition of a combustible, gaseous mixture during a burnoff process and an air flow rate measuring device for performing the method are proposed. The air flow rate measuring device includes a temperature-dependent resistor disposed in a bypass line. Deposits on the surface of the temperature-dependent resistor are removed in a burnoff process, preferably following the opening of the ignition switch. The danger then exists that if the device is used in a motor vehicle, combustible fuel-air mixture located in the vicinity of the temperature-dependent resistor may ignite, and the temperature-dependent resistor would thereby be destroyed because of overheating. For this reason, a slide member is pushed into the flow cross-section during the burnoff process, so that only a small combustible volume is available in the vicinity of the temperature-dependent resistor.
摘要翻译：提出了一种用于防止由于在燃烧过程中燃烧的气体混合物的点燃而引起的由过热引起的流动横截面中的温度依赖电阻的损坏的方法和用于执行该方法的空气流量测量装置。空气流量测量装置包括设置在旁路管线中的温度依赖电阻器。在燃烧过程中，优选在点火开关打开之后，在温度依赖性电阻器的表面上的沉积物被去除。因此存在如下危险：如果该装置用于机动车辆中，位于温度敏感电阻附近的可燃燃料 - 空气混合物可能会点燃，因此温度依赖性电阻器将由于过热而被破坏。因此，在燃烧过程中，滑动构件被推入流动横截面，使得在温度依赖性电阻器附近只有小的可燃体积可用。

摘要： A lambda regulating device is proposed for a fuel metering system in an internal combustion engine with externally supplied ignition. In addition to the regulation means which is already present, multiplicative and additive corrective variables are formed and are stored in non-transient memories. The regulating device enables an additive regulated shutoff of the additive lambda shift during idling and in the lower partial-load range, and it also enables regulation to a symmetrical distance on the part of the regulating manipulation from the limitation. The additive correction may be selected to be in accordance with rpm. Finally, the reference variables for the corrective value may be selected depending upon the air throughput in the intake tube of the engine. With a view to realization of the invention by means of a computer, individual flow diagrams relating to the mode of operation are given in the drawings.

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.
