    • A differential pressure valve is proposed for a fuel injection system of an internal combustion engine. The differential pressure valve includes a diaphragm embodied as the movable valve element, which separates two chambers from one another. A fuel supply line discharges into one chamber and a valve seat carrier provided with a valve opening protrudes into this chamber. This chamber also houses a filter element and a valve spring is disposed coaxially with the valve seat carrier between upper and lower spring plates. The filter element is disposed such that a subsequent change in the tension of the valve spring is also possible. To this end, the filter element can engage the upper spring plate on one side in a sealing manner and on the other side can be supported in a sealing manner in a groove of the wall of the chamber (FIG. 1). In order to assure the free mobility of the filter element, it is provided with an elastically deformable area. As shown in FIG. 2, the filter element may, however, also engage the lower spring plate in a sealing manner and with its other end surroundingly engage the spring plate with as little play as possible, to thereby form a labyrinth seal.
    • 提出了一种用于内燃机的燃料喷射系统的差压阀。 差压阀包括实施为可移动阀元件的隔膜,其将两个室彼此分离。 燃料供给管线排放到一个室中,并且设置有阀开口的阀座承载件突出到该室中。 该室还容纳过滤元件,并且在上下弹簧板之间与阀座承载件同轴设置阀弹簧。 过滤元件被布置成使得阀弹簧的随后的张力变化也是可能的。 为此,过滤元件可以以密封的方式在一侧接合上弹簧板,另一侧可以密封地支撑在腔室的壁的凹槽中(图1)。 为了确保过滤元件的自由流动性,其具有可弹性变形的区域。 如图所示。 然而,如图2所示,过滤元件还可以以密封方式接合下弹簧板,并且其另一端围绕弹簧板尽可能少的游隙接合,从而形成迷宫式密封。

    • A fuel injection system is proposed which serves to supply fuel to a mixture-compressing, externally ignited internal combustion engine. The fuel injection system includes an air flow rate member, which actuates a metering and distribution valve. A reservoir is disposed in a pressure control line which branches off from a fuel supply line, by means of which reservoir a flushing valve can be affected in such a manner that below a certain fuel pressure in the pressure control line the flushing valve is opened, as a result of which the fuel supplied to the individual injection valves can flow back through outflow lines to the fuel tank and thus closes the flushing valve above the certain fuel pressure. Above the certain fuel pressure, the electrical circuit of the starter motor is simultaneously closed. Thus, upon starting the engine, all the lines and units of the fuel injection system are filled with fuel, so that a secure start is assured.
    • 提出了一种燃料喷射系统,其用于将燃料供应到混合物压缩的外部点燃的内燃机。 燃料喷射系统包括空气流量构件,其致动计量和分配阀。 储存器设置在从燃料供给管线分支的压力控制管线中,通过该储存器可以以冲洗阀打开冲洗阀的压力控制线路中的一定燃料压力的方式影响冲洗阀, 结果,供给到各个喷射阀的燃料可以通过流出管路流回燃料箱,从而将冲洗阀关闭在高于某一燃料压力的位置。 高于一定的燃料压力时,起动电动机的电路同时关闭。 因此,在起动发动机时,燃料喷射系统的所有线路和单元都填充有燃料,从而确保了安全起动。

    • A fuel injection system is proposed which serves to provide the most precise possible adaptation of the fuel-air mixture to operating conditions of the internal combustion engine. The fuel injection system includes metering valves, each of which is assigned one regulating valve, whose movable valve element can be exposed on the one hand to the fuel pressure downstream of the respective metering valve and on the other hand to the pressure in a control pressure line, which is limited on the one hand by an electro-fluid converter of the nozzle/bounce plate type and on the other hand by a control throttle. The electro-fluid converter is triggerable in accordance with operating characteristics of the engine. A pressure limitation valve is embodied as a diaphragm valve and serves to regulate the most precise possible system pressure in the engine and, when the engine is shut off, it serves to reduce the fuel pressure in the fuel injection system below the fuel pressure required for opening the injection valves and to block the return flow lines.

    • A metering and distribution valve assembly is proposed for a fuel injection system of an internal combustion engine. The metering and distribution valve assembly includes a control slide having a head 68 and a control edge and a slotted sleeve with at least two control slits. The control edge opens the control slits to a greater or lesser degree in accordance with the relative motion between the control slide and the control slits in the slotted sleeve. An end face of the control slide adjacent to the control edge is exposed to a control pressure which is lower than the system pressure engaging the control edge. The pressure drop at the circumference of the control slide head formed between the control edge and the end face is capable of being influenced in such a manner that the control slide head rests unilaterally on the slotted sleeve at least during a portion of the displacement movement. As a result, better metering precision is obtained. The unilateral resting of the control slide head on one side of the slide bore can be effected either by the application of fuel at system pressure at the aperture or by the application of fuel at control pressure at the longitudinal groove.
    • 提出了一种用于内燃机的燃料喷射系统的计量和分配阀组件。 计量和分配阀组件包括具有头部68和控制边缘的控制滑块以及具有至少两个控制狭缝的开槽套管。 根据控制滑块和开槽套筒中的控制狭缝之间的相对运动,控制边缘或多或少地打开控制狭缝。 与控制边缘相邻的控制滑块的端面暴露于低于与控制边缘接合的系统压力的控制压力。 控制滑动头在控制边缘和端面之间形成的圆周处的压降能够受到影响,使得控制滑动头至少在位移运动的一部分期间单向地搁置在开槽套筒上。 结果,获得更好的计量精度。 控制滑动头在滑动孔的一侧上的单侧休息可以通过在孔的系统压力下施加燃料或通过在纵向槽处的控制压力下施加燃料来实现。

    • A fuel supply device, which serves to predetermine a fuel quantity that is proportional to the aspirated air quantity, and also serves to spread the air-fuel mixture. The fuel supply device includes an air metering device, which is arranged in the air intake manifold of the internal combustion engine and activates a fuel metering device, which has a control slit that opens a control groove by a varying amount. The control slit and the control groove are rotatable relative to each other, and the control groove has at least one control edge, which overlaps the control slit and is formed at an angle relative to the axis of rotation. The control slit is arranged in a guide sleeve and the control groove is arranged in a rotatable sleeve mounted in the guide sleeve with the rotatable sleeve being arbitrarily shifted relative to the guide sleeve. A connecting tube is arranged between the rotatable sleeve and the mounting axis of the air metering device, by means of which the metered fuel can be fed to a nozzle arranged on the air flow rate meter. For a better mixture spreading effect, air can be fed to the metered fuel through a filter composed of a fine-meshed web.
