Patentiert im Deutschen Reiche vom 6. Mai 1922 ab.Patented in the German Empire on May 6, 1922.

Ks sind' bereits selbsttätige elektrische Wärmereguliereinrichtungen für Heizkörper bekannt, bei welchen Kondensatoren eingeschaltet sind. Die vorliegende Erfindung un-ιerscheidet sich von dem Bekannten jedoch darin, daß zwei Kondensatoren vorgesehen sind, von welchen der eine mit dem elektrischen Steuerungsmittel, z. B. dem Solenoid eines Relais, und ein zweiter mit dem Konto taktthermometer verbunden sind und zueinander in Parallelschaltung liegen Dies besitzt den praktischen Vorteil, daß der an dem Solenoid vorhandene Kondensator die Induktionswirkung aufnimmt, wodurch Be-Schädigungen des Thermometers vermieden werden, wenn die Stadtnetzleitung mit bedeutender Vorspannung benutzt wird.
In der Zeichnung zeigt:

However, the present invention differs from the known in that two capacitors are provided, one of which is connected to the electrical control means, e.g. B. the solenoid of a relay, and a second are connected to the account clock thermometer and are connected in parallel to each other is used with significant bias.

Abb. 2 eine Einzelheit.
Die Einrichtung besitzt ein aus einem U-Rohr A mit Expansionsschenkel F bestehendes Kontaktthermometer. Eine Elektrode E ist von oben her in das Rohr A eingeführt. Der Ansatz G (Abb. 2), welcher in bekannter Weise einen Zylinder und Kolben für die Einstellung der Temperatur trägt, kann entweder bei D oder bei D1 angeschlossen sein. Der Rückleitungsstromkreis wird durch eine Platinelektrode aufgenommen, welche in dem Boden des U-Rohres A eingeschmolzen ist. Die Erweiterungen H des Rohres dienen dem Zweck, dieses Rohr von kleinem Umfang zu wählen, wenn eine Flüssiglceit von hoher Expansion und Empfindlichkeit in Benutzung gelangt. Das Solenoid C ist an das bekannte Relais angeschlossen. Erfindungsgemäß sind zwei Kondensatoren B1 und B2 getrennt vorgesehen, und zwar ist der Kundensator B1 mit dem Solenoid des Relais und der Kondensator B- mit dem Rohr A des Kontaktthermometers verbunden, und beide liegen in Parallelschaltung zueinander. Durch diese Einrichtung wird die Funkenbildung bei der Unterbrechung vermieden, wenn stärkere Spannungen bis zu 250 Volt erzeugt werden.Fig. 2 a detail.
The device has a contact thermometer consisting of a U-tube A with an expansion leg F. An electrode E is inserted into the tube A from above. The approach G (Fig. 2), which carries a cylinder and piston for setting the temperature in a known manner, can be connected either at D or at D 1 . The return circuit is taken up by a platinum electrode which is melted into the bottom of the U-tube A. The extensions H of the tube serve the purpose of choosing this tube of small size when a liquid of high expansion and sensitivity comes into use. The solenoid C is connected to the known relay. According to the invention, two capacitors B 1 and B 2 are provided separately, namely the customer B 1 is connected to the solenoid of the relay and the capacitor B is connected to the tube A of the contact thermometer, and both are connected in parallel to each other. This device prevents sparking during interruption when higher voltages of up to 250 volts are generated.
