Description

Die Erfindung bezieht sich auf Drosselspulen, deren einer Schenkel zur Einstellung der jeweils erforderlichen Induktivität mit einem regelbaren Luftspalt versehen ist. Derartige Drosselspulen sind beispielsweise zur Speisung von Entladungslampen geeignet und gestatten, ihre Charakteristik den Betriebsbedingungen anzupassen.The invention relates to choke coils, one leg of which is used for adjustment the required inductance is provided with an adjustable air gap. Such Choke coils are suitable, for example, for feeding discharge lamps allow their characteristics to be adapted to the operating conditions.

Erfindungsgemäß ist die Anordnung so ge-According to the invention, the arrangement is so

> troffen, daß der Schenkel an seinem einen Ende drehbar und am andern, dem Luftspalt zugekehrten Ende in einem Winkel ungleich> The fact that the leg is rotatable at one end and the other, the air gap facing end unequal at an angle

900 zu seiner Achse abgeflacht ist, wobei der90 0 is flattened to its axis, the

diesem Ende zugekehrteTeil des magnetischenthis end facing part of the magnetic

Kreises vorzugsweise die gleiche Abflachung aufweist. Damit der möglichst gering zu haltende Luftspalt an dem drehbar befestigtenCircle preferably has the same flatness. So that the as low as possible holding air gap on the rotatably attached

Ende des Schenkels bei seiner Schwenkung keine Änderung erfährt, wird dieses Ende sowie der entsprechende Kernteil abgerundet ausgebildet. Die Schwenkung erfolgt hierbeiIf the end of the leg does not change when it is pivoted, this end is as well the corresponding core part is rounded. The pivoting takes place here

S des Luftspaltes bewirkt werden kann.S of the air gap can be effected.

Gemäß dem Ausführungsbeispiel nach der Erfindung ist ähnlich der Mantel type ein rechteckiger Eisenkern I mit einem Mittelschenkel 2 vorgesehen, der die Wicklung 3 trägt und schwenkbar angeordnet ist. Der Schenkel 2 wird von zwei Wangen 4 gehalten, .die an ihrem einen Ende im Kern 1 bis 5 drehbar gelagert sind. Schenkel 2 und Kern 1 sind an dieser Stelle bei 6 so abgerundet, daß- sich der Luftspalt hier bei der Schwenkung des Schenkels nicht ändert.According to the embodiment of the invention, the jacket type is similar to a rectangular one Iron core I is provided with a central leg 2 which carries the winding 3 and is pivotably arranged. The leg 2 is held by two cheeks 4, .die are rotatably mounted at one end in the core 1 to 5. Leg 2 and core 1 are rounded at this point at 6 so that the air gap is here when the Schenkels does not change.

Das andere Ende 7 des Schenkels ist ebenso wie der zugeordnete Teil 8 des Kernes 1 unter einem Winkel ungleich 90 ° zu seiner Achse abgeflacht. Auf diese Weise ist dann eine äußerst feine Regelmäßigkeit gegeben. Zwecks Einstellung weisen die Wangen 4 noch Öffnungen 9 auf, mit denen der Exzenter 10 zusammenwirkt, so daß bei dessen Drehung die Lage des Schenkels 2 innerhalb bestimmter Grenzen geändert werden kann.The other end 7 of the leg is just like the associated part 8 of the core 1 below flattened at an angle not equal to 90 ° to its axis. In this way then is one given extremely fine regularity. For the purpose of adjustment, the cheeks 4 also have openings 9 with which the eccentric 10 cooperates, so that when it is rotated, the position of the leg 2 can be changed within certain limits.
