Es sind wellen-lineare Drehkondensatoren bekannt, deren Rotorbleche eine Durchbrechung aufweisen, die der Gestalt, Größe und Anordnung einer Aussparung in den Statorblechen entspricht und sich bei vollkommen eingeschwenktem Rotor mit dieser deckt. Die bekannte Gestalt der Aussparung in den Stator- und Rotorblechen von Drehkondensatoren weist aber den Mangel auf, daß sieThere are wave-linear rotary capacitors known, the rotor laminations of which have an opening have the shape, size and arrangement of a recess in the stator laminations corresponds to and coincides with this when the rotor is completely swiveled in. The well-known shape of the recess in the However, stator and rotor laminations of variable capacitors have the disadvantage that they

Die Erfindung betrifft einen frequenzlinearen Drehkondensator mit Durchbrechungen und Aussparungen der oben gekennzeichneten Art, durch den der genannte Mangel in einfachster Weise dadurch beseitigt wird, daß erfindungsgemäß die Statorbleche einen durch die Aussparung gebildeten Lappen solcher Form und Lage aufweisen, daß er bei Beginn des Einschwenkens des Rotors zunächst von den Rotorblechen überdeckt und beim Weiterdrehen des Rotors durch die Durchbrechung wieder freigegeben wird.The invention relates to a linear frequency variable capacitor with openings and recesses of the type identified above, through which the said deficiency is eliminated in the simplest manner is that, according to the invention, the stator laminations have a tab formed by the recess have such a shape and position that it is initially covered by the rotor laminations and at the beginning of the pivoting of the rotor is released again when the rotor continues to rotate through the opening.
Der wesentliche technische Fortschritt eines Drehkondensators nach der Erfindung liegt
darin begründet, daß ein frequenz-linearer Drehkondensator geschaffen ist, der in seinen
Ausmaßen denjenigen eines normalen Kondensators entspricht, so daß er normalerweise
anStelle eines der bekannten Drehkondensatoren in jeden vorhandenen Radioapparat
eingebaut werden kann.
In der Zeichnung ist der frequenz-lineare Drehkondensator gemäß der Erfindung an
einem Ausführungsbeispiel in den Abb.i bis 4 in verschiedenen Stellungen der Rotorbleche
zu den Statorblechen dargestellt, und zwar zeigtThe essential technical progress of a variable capacitor according to the invention is based on the fact that a frequency-linear variable capacitor is created, which corresponds in its dimensions to those of a normal capacitor, so that it can normally be installed in place of one of the known variable capacitors in any existing radio set.
In the drawing, the linear-frequency variable capacitor according to the invention is shown in an exemplary embodiment in Figs

Die Statorbleche α besitzen eine etwa oval gestaltete Aussparung b, durch welche Lappen c, d gebildet werden, von denen derjenige d gegen den Lappen c etwas zurückspringt. Die Rotorbleche e besitzen Durchbrechungen /, die so angeordnet und ausgebildet sind, daß sie sich im wesentlichen mit den Aussparungen b der Statorbleche a decken, wenn der Rotor vollkommen in den Stator eingeschwenkt ist. Durch diese ganz bestimmte Anordnung der Aussparungen b und f in den Blechen α und e, wodurch anfangs beim Einschwenken des Rotors der Lappen d des Stators überdeckt wird, um beim weiteren Einschwenken des Rotors durch die Aussparung / wieder freigegeben zu werden, wird erreicht, daß die Kapazitätszunahme des Kondensators nach der in Abb. 5 dargestellten Kurve anfangs außerordentlich gering ist, so daß die zugehörige Frequenz dieser Kurve in graphischer Darstellung auch in ihrem unteren Teil als gerade Linie verläuft.The stator laminations α have an approximately oval recess b, through which tabs c, d are formed, of which the one d jumps back somewhat against the tab c. The rotor laminations e have openings / which are arranged and designed in such a way that they essentially coincide with the recesses b of the stator laminations a when the rotor is swiveled completely into the stator. This very specific arrangement of the recesses b and f in the metal sheets α and e, which initially covers the tab d of the stator when the rotor is pivoted in, in order to be released again when the rotor is further pivoted through the recess / the increase in capacitance of the capacitor according to the curve shown in Fig. 5 is initially extremely small, so that the associated frequency of this curve runs as a straight line in its lower part as well.
