Description
Die Erfindung betrifft einen elektrischen Kondensator mit-veränderlicher Kapazität. , ■ ; . ■ Von den für Regel— und Lleßzv/ecke bekannten veränderlichen ϊΖοη-The invention relates to an electrical capacitor with variable capacitance. , ■; . ■ Of the variable ϊΖοη- known for rule and Lleßzv / ecke
■ densatoren unterscheidet sich die erfindurgsgemäße Ausführung dadurch, daiS- das Dielektrikum aus V/eichguirjr.i oder einer gleichartig wirkenden hochelcstischen Hitir.se' besteht und in seiner Schichtdicke durch Druck oder Zug veri-.r.cert --.vird« Auch die Beläge können rans oder ttvil-.veise evs elektrisch li-itfähigen GummiEiischungen bestehen und sie können mit den Dielektrikum - durch Verkleben oder Zusamr.-envulkani .?ioren zu einem · f ormanpas-.'cungsi'shigen Körper zusammengeschlossen .sein. . Derartige erfindungsgemäße Kondensatorausführungen bieten gegenüber den bekannten Ausführungen erweiterte Anwendungsmöglichkeiten.und auch sonstige Vorteile* Die Kondensatoren •sprechen auf Druck bezw· auf Dehnung an. Eine auf Druck ansprechende Art kann z.B. in einfacher Weis.e dadurch verwirklicht werden, daß zwischen Schichten aus elektrisch le.itend;en Stoff enr z.B. . zwischen-JiIetallscheiben, Weichgummi scheiben ge- ■ legt und das Ganze durch Druck verformt wird. Durch den wechselnden Anstand der Metallseheiben ändert sich die'Kapazität» Eine solche Bauart ermöglicht für Abgleich- und Regelkondensatoren eine .bisher nicht gekannt einfache, billige.Bauart •und kommt aueh für Meßzwecke in Frage» ■ , "..'·■ ; Andere Ausführungen "bestehen aus einer oder mehreren Schichten von elektrisch isolierendem.Gummi als Dielektrikum und Belägen aus elektrisch leitfähigen Gununimischungeh oder dehnungsfähi- ■ gen leitenden Aufstrichen und können sowohl auf Zusammendrücken ?rie auch s.uf Dehnung ansprechen. Bei der Dehnung vergrößertsich die Fläche der Beläge, außerdem niEmt die Dicke der als Dielektrikum wirkenden Gummischicht ab. Beice Wirkungen ergänzen sich im- Sinne einer Kaρazitatεzunehme.,Auch bei.Beanspruchungen des Kondensators auf Dehnung ist es :J.ent unbedingt erforderlich, daß beide Belage c-us. hcoiiel:. ^tischen Stoffen bestehen, vielmehr kann der c-ine der -'.-.eioen Belage aue einem' : vergleichsweise starren Körper, bestehen. . ' .The embodiment according to the invention differs from the capacitors in that the dielectric consists of V / Eichguirjr.i or a similarly acting highly elastic Hitir.se ' and its layer thickness is verified by pressure or tension - Coverings can consist of rans or ttvil-.veise evs electrically li-itable rubber compounds and they can be connected to the dielectric - by gluing or amalgamating envelopes to form a form-adaptable body. . Such capacitor designs according to the invention offer expanded application possibilities and also other advantages compared to the known designs. The capacitors respond to pressure or expansion. A type that responds to pressure can, for example, be implemented in a simple manner by electrically conducting between layers of ; en substance en r eg. between metal and soft rubber disks and ■ the whole thing is deformed by pressure. Due to the changing spacing of the metal discs, the 'capacity changes. »Such a design enables a previously unknown, simple, cheap design for balancing and regulating capacitors and can also be used for measuring purposes» ■, "..' · ■; Others Versions "consist of one or more layers of electrically isolating rubber as a dielectric and coverings made of electrically conductive Gununi mixtures or stretchable conductive coatings and can respond to both compression and stretching. When stretching, the surface of the coverings increases, and the thickness of the rubber layer, which acts as a dielectric, decreases. Both effects complement each other in the sense of a Kaρazitatεsteiger., Even with. Stresses of the capacitor on expansion it is: J.ent absolutely necessary that both coverings c-us. hcoiiel :. ^ table materials, rather the c-ine of the -'.-. egg covering can consist of a ' : comparatively rigid body. .
