As shown in the drawing, an embodiment of the present invention has an α ¹ alternating current generator 10 as the supply source for the electrical energy, which is connected to the rest of the circuit via a single-pole double-position switch 11 which is fed into the supply lines 12 and 13 Input into the circuit under consideration. A correspondingly enclosed low-pass filter 15, 16 is connected to each line, which filters out undesired high frequencies, noise frequencies and the like, thereby preventing extraneous frequencies from being fed back into the generator and other devices fed by the generator. In the special embodiment shown, the filter has Mebenchlußkondensatoren 17 connected between E-de and a main feed line, with an inductance or a choke coil in each main feed line between the shunt capacitors and the supply source, ie feed lines behind the filters 15, 16 are designated by 18 and 19.

The lines 18 and 19 have opposite ends 20 and 21 of an inductance coil 22 is connected. The coil 20 is parallel to a variable resistor 23 and a primary coil 24 one Transformer 25 connected, with resistor and transformer coil in

Are clipped in series. Parallel to the transfer coil 24, there are two in » Series-connected diodes 26 placed, the diode 26 being a silicon leveler and the diode 27 is a voltage regulating Zener diode. The ^ iodenkombination 26 and 27 represents a voltage control loop in which one half of the input voltage curve in the Transformer 25 is trimmed. This helps to achieve the appropriate timing of the trigger pulse over the ignition system area the input voltage and frequency according to the invention at *

The secondary coil 28 of the transformer 25 feeds a voltage diode rectifier 29. One terminal of the rectifier 29 is connected to one end of the transmitter coil 28, the other transmitter terminal is placed on an electrode 30 of a control spark gap 31. The other electrode 32 of the spark gap 31 is grounded. Further a tripping capacitor 33 is connected to the spark gap device 31, one terminal of which is connected to the electrode 30 and the other

a. whose terminal is connected to the primary coil 34 of the pulse transformer 35.

The other end of the - ^ rimärspule 34 is grounded. The secondary coil 36 one end of the pulse transmitter 35 is also between earth and! primary winding 34 is placed and the other end is to an outer one • Electrode 37 of a control spark gap 38 connected.

Furthermore, a rectifier circuit with a relatively high voltage is connected to the same supply source 10; she knows a transformer 40, the primary winding 41 of which has one end is connected to the terminal 21 of the inductance coil 22 and the other end of which is grounded. The secondary winding 42 of the transformer 40 feeds a voltage doubling circuit 43 »the one diode 44 has, one terminal of which with one end 45 of the coil winding 42 is connected and polarized in one direction, as well as one

Another diode 46, one terminal of which is connected to the same coil winding terminal 45, but is polarized opposite to the diode 44. A resistor 47 is connected between the other terminal of the diode 44 and earth. ^z wei series connected capacitors 49 and 50 between the other terminal 51 of the diode 46 and earth are connected, and the center 52 of the series-connected capacitors is connected to the other end 53 of the secondary coil 42 of the transformer 40th A capacitor 57 is placed in parallel with the primary coil 41 and a capacitor 58 in parallel with the coil 22 so that high frequency interference which may have been introduced into the ignition system from all supply sources and which would result in faulty ignition can be weakened or eliminated.

When the voltage feed adopts a certain phase position, only the iode 46 is conductive and it only conducts in one direction.

in device and thus causes the capacitor 49 to move / one direction charges. In the event of a phase reversal of the supply voltage, the diode 44 alone conducts current and causes the capacitor 50 to charge, where the charge has the same polarity as that of the charge which is applied to the capacitor 49. Since both capacitors are connected in series in their discharge circuit, add up their voltages so that the supply voltage is doubled.

The capacitor terminal 51 is connected to a resistor 59, whose the opposite end is connected to a terminal 55 of a storage capacitor 54, while the other terminal of the capacitor 54 DiA is ungrounded terminal 55 of capacitor 54 is with the other end of the transformer coil 28 connected.

The terminal 55 of the capacitor 54 is connected to an electrode 60 of the spark gap 38 and is also connected to a terminal 61 of a capacitor 62, the other terminal of which ends at one end 63 of the primary winding 64 which forms part of a pulse transmitter 65. The other end 66 of the primary winding 64 is placed on the other electrode 67 of the spark gap 38. The secondary winding 68 of the transformer 65 is connected to one end at the terminal 67 of the spark gap, while the other end 69 of the winding is connected to a discharge gap or a spark plug 70 which has the usual spark gap 71 which is shunted to a resistor 72 can be placed, which bridges the spark gap in the form of a semiconductor surface. The other side of the discharge spark gap is connected to earth. A low resistance resistor 73 is connected to the spark gap electrode 67 with one terminal, and the other end is grounded. ]

For the excitation of high energy level, the voltage of the power source 10 is connected via the switch 11 in the ^E ingangsleitung 12! so that the full line voltage, which is in the order of magnitude of 100 - 120 V at 400 Hz, is applied to the primary winding 41 of the transformer 40. The voltage occurring at the transformer 25 is largely reduced to zero because the primary coil is effectively short-circuited. On the other hand, the full supply potential occurs at converter 40 and the voltage that occurs at discharge capacitor 54 becomes relatively high.

The charge on capacitor 54 to its peak value as through the voltage doubling circuit 43 is set, causes a , similar charging of the capacitor 62 is made. The charge of the capacitor 62 enables its voltage to occur at the spark gap electrodes 60, 67 of the spark gap 38, where = - becomes ionized and conductive through the gap. In the case of a power line, the capacitor 62 discharges via the spark gap 38, whereby the current can flow through the coil 64 and a high voltage in dea? Secondary coil 68 induced. The high tension the coil 68 is abandoned via the discharge path 71, whereby ionization and power conduction is caused. When the discharge path 72 is conductive, the discharges Storage capacitor 54 across the gap and generates the ignition spark required for combustion.

The operation of the arrangement for feeding in high-level energy at a relatively high voltage is described above, as is the case, for example, when starting an internal combustion engine. For continuous operations, namely when operating with E _n ergie low level, the power source 10 is switched by the switch 11 to the input line. 13 The full line voltage now occurs partially at the induction coil 22 and the primary winding 41 of the transformer 40, which are in series with it. is switched on. The voltage on the coil 22 appears on the primary coil 24 of the transformer 25 'so that the transformer is excited, as opposed to no excitation in the case of the high level energy. Since the transformer 40 is now given a low voltage on its primary winding, it is less strongly excited than in operation with high-level energy. However, the capacitor 33 is charged to a voltage which is determined by the voltages

which occur on the secondary coil 28 and the capacitor 54. There ' these voltages add up due to the series connection appear the combined voltages on capacitor 33. The same accordingly, a relatively high voltage also occurs at the spark gap 31 on., This relatively high voltage is sufficient to produce a To effect ionization and power conduction of the spark path 31 ". At of a power line of the spark gap 31, the capacitor 33 discharges look over the spark gap and the resulting current flow goes through the coil 34 of the pulse transmitter 35 * A high voltage becomes Induced in the secondary voltage 36, this voltage occurs at the Electrode 3? and causes the ionization of the gap 38. The The spark gap then breaks down and becomes conductive.

The ionization and current conduction of the spark gap 38 in the above Way allows that due to the discharge of the capacitor 62 and the resulting current flow high induced voltage at the secondary coil 68 and the discharge path 71 in the manner described above in connection with the operation high energy level is induced «, the discharge capacitor 54 with a due to the lower voltage at the transformer 40

the supply source 110 is connected to the input line 113 via the switch 111 switched. The full line voltage now occurs partially at the induction coil 122 and the primary winding 151 of the 150 which is in series with it. The tension on the Coil 122 appears essentially on the primary coil 128 of the transformer 129, so that the transformer is more strongly excited than in FIG the previously described trap of high level energy. Since that too Transformer 150 abandoned a lower voltage on its primary winding is, it is less excited than in the aforementioned case with high level energy. This results in the storage capacitor 134 is charged to a higher voltage level and the charging capacitor 164 is charged to a lower voltage level will. Since both capacitors 134 and 164 are connected in series and their values add up, this voltage summation is still sufficient to ionize and conduct current of the fun- * cut distance 135 to be effected. With a power line of the spark gap 135, the above-described operation is repeated to the extent that the spark gap 142 because of the peak voltages that are applied to the Electrodes 141 and 143 occur, is ionized again and accordingly breaks through and becomes flow-conducting. Thus, the discharge / capacitor 164 discharges, which has a reduced voltage because of the lower has voltage occurring at the transformer 150, nevertheless via the spark gap 142 after its breakdown. Because the Voltage appearing across the discharge capacitor 164 over long periods of time, i.e. during continuous operation of the incinerator is decreased when the level is low

The life of the capacitor is considerably increased and the probability an error in operation is significantly reduced.
