它提出了一种燃料喷射系统，其被用于向内燃机的操作条件精确调整可能的燃料 - 空气混合物的。 所述燃料喷射系统包括计量阀（1），每个具有在一方面的下游的各自的计量阀的燃料压力的控制阀（13），所述可动阀件（14）相关联的（1），并通过一个控制压力管路在另一方面（21）由一控制压力阀作用时，一方面 （20，20”，20“）中的喷嘴挡板型和由控制节气门（23），另一方面是有限的。该控制压力阀（20，20' ，20" ）包括永久磁铁（101）和上电磁铁（99） 其磁通穿过的电枢（85，106，106“）以这样的方式，在至少一个空气间隙，所述永磁体（101）和电磁体（99）的磁通量在相同的方向上延伸，被引导而永磁体的磁通量（101 ）并且在至少一个其它空气间隙电磁体（99）在相反的方向上彼此延伸。这样的设计需要显著较低的驱动功率降 小号电磁体（99）。 控制压力阀打开，使得在所述控制阀（13）作用控制压力导致控制阀（13）和燃料喷射由所述电磁体（99）的励磁电流的逆转停止的关闭。

It is proposed a fuel injection system, which is used for giving an accurate adjustment of the fuel-air mixture at the operating conditions of the internal combustion engine. The fuel injection system comprises metering valves (1), each of which is a control valve (13) associated with the movable valve member (14) on the one hand by fuel pressure downstream of the respective metering valve (1) and on the other hand by a control pressure line (21) is acted upon, on the one hand by a control pressure valve (20, 20 ', 20 ") in the nozzle-flapper type and on the other hand by a control throttle (23) is limited. The control pressure valve (20, 20', 20") comprises a permanent magnet (101) and an electromagnet (99) on whose magnetic flux across an armature (85, 106, 106 ") is guided in such a way that in at least one air gap, the magnetic flux of the permanent magnet (101) and solenoid (99) extends in the same direction, while the magnetic flux of the permanent magnet (101 ) and electromagnet (99) runs in the opposite direction in at least one other air gap to each other. such a design requires a significantly lower driving power of the electromagnet (99). By reversal of the excitation current of the electromagnet (99), the control pressure valve is opened so that the on the control valves (13) acting control pressure leads to a closing of the control valves (13) and the fuel injection is inhibited.
