Description

    Elektrisch erwärmter Thermostat.   



   Die üblichen mit einer Flüssigkeit oder mit einer leicht schmelzbaren Masse gefüllten Thermostaten, wie sie z. B. bei selbsttätigen Schaltern oder zum Schutz von Transformatoren verwendet werden, 
 EMI1.1 
 an einem Ende mit einer Büchse 4, am andern Ende mit einem   einsehraubbaren     Dpckel'2 verseheJl   ist. Wird der Zylinder z. B. durch eine Heizwicklung 1 erwärmt, dann dehnt sich die   Füllung     J im Innern   des Zylinders infolge der   Wärmewirkung aus   und treibt den   Kolben J heraus. Durch häufiges Überhitzen   
 EMI1.2 
 so dass man mit einem verlässlichen Arbeiten des Thermostaten nicht mehr rechnen kann. 



   Der Gegenstand der Erfindung besteht darin, dass die Füllung des Zylinders durch ein auf elektrolytischem Wege zerstäubtes, magnetisch leitendes Metall, wie z.   B. Eisen gesättigt   wird. Dadurch erhöht sich die Wärmeleitfähigkeit der Fiillung, welche überdies einen magnetischen Leiter von grosser Permeabilität darstellt. Der von der Heizspule erzeugte magnetische Fluss verursacht in der Füllung eine Wirbel-   stromenvärmung,   wodurch der Thermostat wesentlich empfindlicher arbeitet. Durch die Sättigung der Füllung mit Metall ist ausserdem eine molekulare   Strukturänderung   durch Überhitzen hintangehalten. 



  Der Zylinder selbst wird vorzugsweise aus Messing hergestellt, damit die Wirbelstromwirkung hauptsächlich auf die Füllung beschränkt bleibt.

    Electrically heated thermostat.



   The usual thermostats filled with a liquid or with an easily meltable mass, as they are e.g. B. used for automatic switches or to protect transformers,
 EMI1.1
 is provided at one end with a sleeve 4 and at the other end with a screw-in plug 2. If the cylinder z. B. heated by a heating coil 1, then the filling J expands inside the cylinder as a result of the heat effect and drives the piston J out. From frequent overheating
 EMI1.2
 so that the thermostat can no longer be expected to work reliably.



   The object of the invention is that the filling of the cylinder by an electrolytically atomized, magnetically conductive metal, such as. B. iron becomes saturated. This increases the thermal conductivity of the filling, which, moreover, represents a magnetic conductor of great permeability. The magnetic flux generated by the heating coil causes eddy currents to heat up in the filling, which makes the thermostat much more sensitive. Due to the saturation of the filling with metal, a molecular structural change due to overheating is prevented.



  The cylinder itself is preferably made of brass so that the eddy current effect is mainly limited to the filling.
