Description

Anordnung bei Batteriezündeinrichtungen für Verbrennungsmotoren zum selbsttätigen Unterbrechen des Zündstromkreises mittels eines Thermostaten. Die Erfindung betrifft eine Verbesserung der durch das Patent 376752 geschützten Batteriezündreinrichtuwg; bei der der primäre Zündstromkreis bei dauerndem Stromfuß durch einen Thennostaten unterbrochen wird, um ein Dürchbrennen vier Zündspule oder die Erschöpfung der Batterie zu verhüten. Die Heizspule des Thermostaten ist dabei in einen Hilfsstromkreis eingeschaltet, der durch ein im primären Zündstroanecreis liegendes Relais geschlossen wird, sobald der Primärstrom dauernd fließt.Arrangement in battery ignition devices for internal combustion engines for the automatic interruption of the ignition circuit by means of a thermostat. The invention relates to an improvement in the battery ignition device protected by patent 376752; in which the primary ignition circuit is interrupted by a thennostat with a permanent current foot in order to prevent the ignition coil from burning through or the battery being exhausted. The heating coil of the thermostat is connected to an auxiliary circuit which is closed by a relay in the primary ignition circuit as soon as the primary current flows continuously.

Während nun bei den im Hauptpatent angegebenen# Ausführungsbeispielen dieses Relais ein besonderer Apparat ist, bildet nach der Erfindung die Primärspule der Zündeinrichtung zugleich das Relais. Hierdurch wird die Anordnung wesentlich vereinfacht.While now in the # embodiments specified in the main patent this relay is a special device, according to the invention it forms the primary coil the ignition device at the same time the relay. This makes the arrangement essential simplified.

Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes schematisch :wiedergegeben.The drawing shows an embodiment of the subject matter of the invention schematic: reproduced.

Der aus einer Batterie a gespeiste ZümdstromkTeis enthält wie beim Hauptpatent die Primärspule b, die Kontakte des Unterbrechers c und! die vom Thermostaten g beeinrlußten Trennkontakte h. Der Erfindung gemäß ist der Hilfsstromkreis mit der Heizspule f des Thermostaten über ein Kontaktpaar o geführt, dessen beweglicher Kontakt an einem von der Primärspule b beeinflußten Anker p sitzt.The ZümdstromkTeis fed from a battery a contains as with Main patent the primary coil b, the contacts of the breaker c and! the one from the thermostat g affected isolating contacts h. According to the invention, the auxiliary circuit is with the heating coil f of the thermostat passed through a pair of contacts o, the more movable Contact is seated on an armature p influenced by the primary coil b.

Beim normalen Betrieb der Zündeinrichtung ist der .Stromfluß im Zündstromkreis von so kurzer Dauer, daß die Zübndspule ihren Anker p nicht anzieht und daher die Kontakte o nicht geschlossen :werden. Diese .Wirkung kann noch durch Verzögerungsmittel bekannter Art unterstützt werden. :Sobald aber in dem Zündstromkreis ein Dauerstrom fließ, was dann der Fall ist, wenn bei geschlossenem Zündungsschalter j und stillstehendem Motor die Unterbrecherkontakte sich in geschlossener Stellung befinden, zieht die Spule b den Anker p an und schließt die Kontakte o. Dann fließt in dem Hilfsstromkreis ein .Ström über die Heizspule f des Thermostaten g. 'Dieser tritt nach einiger Zeit in Wirksamkeit, indem er sich nach rechts krümmt. Dadurch ,gibt eine an dem freien Ende des Thermostaten vorgesehene Nase k, die bei gestrecktem Thermostaten die Kontakte h geschlossen hält, die unter darr Zug einer Feder i stehende Kontaktzunge q frei. Es .öffnen sich also die Kont*te h, so daß der primäre Zündstromkreis an dieser Stelle unterbrachen ist.During normal operation of the ignition device, the current flow in the ignition circuit is of such a short duration that the ignition coil does not attract its armature p and therefore the contacts o are not closed. This effect can also be supported by delay means of a known type. : But as soon as a continuous current flows in the ignition circuit, which is the case if the breaker contacts are in the closed position with the ignition switch j closed and the engine stopped, the coil b attracts the armature p and closes the contacts o. Then flows in the Auxiliary circuit in. Flow through the heating coil f of the thermostat g. 'This comes into effect after a while by bending to the right. As a result, a nose k provided at the free end of the thermostat, which keeps the contacts h closed when the thermostat is extended, releases the contact tongue q , which is under the tension of a spring i . The accounts h open up so that the primary ignition circuit is interrupted at this point.

Zum Wiederschließen des Zündstromkreises muuß man die Kontakte h durch einen Handschalter m wieder miteinander in Berührung bringen.. Bei Fahrzeugen, die einen elektrischen Anlasser haben, bringt man zweckmäßig den Schalter m mit dem Anlasserschalter so in Verbindung; daß beim Schließen des Anlasserschalters zugleich die Kontakte h geschlossen werden.To reconnect the ignition circuit, the contacts h must be through bring a hand switch m back into contact with each other .. For vehicles that have an electric starter, it is useful to bring the switch m with the Starter switch so in connection; that when closing the starter switch at the same time the contacts h are closed.
