の実施例の回路図を参照して本発明を説明する。The solution to this problem is to connect a capacitor in parallel with the control winding, the size of which is such that the induced control voltage at limit speeds no longer reaches the control threshold of the semiconductor switch. It is done by being designed. A gradual change in the limit speed can be carried out by switching on and off further capacitors. Furthermore, it is preferable to connect a thermistor in parallel with the control winding. The use of variable components allows a problem-free construction of a reliable device that can be easily connected to existing ignition systems. The present invention will be described below with reference to circuit diagrams of embodiments of the present invention.

火栓８での火花発生の公知の過程となる。As the field spider 1 rotates, a voltage is continuously induced in the charging winding 3. The positive half wave of the voltage is diode 4
The capacitor 5 is charged via. In control winding #9, a voltage pulse is induced at the point of ignition of the internal combustion engine by means of a suitable configuration of a given permanent magnet 2, and a resistor circuit which loads the control winding specifically in order to ensure an uninterrupted control function. It is applied to the network 1o. The positive control pulse reaches the gate terminal of thyristor B via diode 11 and turns it on. The capacitor 5 can therefore be discharged via the primary winding of the ignition coil 7 and the known process of spark generation at the ignition plug 8 results.

まで増加する。The control winding 9 is additionally loaded by a capacitor 13, which load changes as the frequency of the control pulses increases, so that as the rotational speed of the internal combustion engine increases, the control pulses no longer reach the full length. This control pulse is increased until it is lowered, as long as the control threshold required for injection is not reached.

必要とする内燃機関へ使用する場合に有利である。Therefore, the spark plug 8 no longer produces a spark, and the rotational speed of the internal combustion engine drops to a value lower than the predetermined limit rotational speed. The size of the capacitor +6 depends on the combined resistance of the control circuit and the limit rotational speed to be determined. A relatively small capacitor results in a relatively high limiting speed. Therefore, by turning on and off the additional capacitor 12 using the switch 15, it is possible to adjust to a relatively low or relatively high limit rotational speed. This is advantageous when used in internal combustion engines which require different limit speeds.
サーミスタ１４が加熱で比較的低い抵抗値をとり、した
がって制御回路全体の温度の影響を補償するので、限界
回転数の変動は加熱で縮小される。The fluctuations in the limit rotational speed are reduced on heating, since the thermistor 14 assumes a relatively low resistance value on heating and thus compensates for the influence of the temperature on the entire control circuit.
