Description

Wärmeregler mit Hebelübersetzung und Einstellvorrichtung für die Regeltemperatur DieErfindung bezieht sich auf einenWärmeregler mit Hebelübersetzung, bei dem die Regeltemperatur einstellbar ist. Erfindungsgemäß erfolgt die Einstellung der Regeltemperatur durch Drehen eines Stabes von geringer Wärmeausdehnung, der an seinen beiden Enden Gewinde verschiedener Ganghöhe besitzt. Der Erfindungsgegenstand ist in den Abb. r bis 3 dargestellt und besteht aus einer Metallröhre A mit Kontaktgehäuse, einem stabförmigen Körper B geringen Wärmeausdehnungsvermögens, einem Hebel C und der mit einem Spielraum an den Hebel C gelagerten Spannmutter D. Der stabförmige Körper B hat an beiden Enden Gewinde von verschiedener Ganghöhe, deren eines in eine am Gehäuse fest angebrachte Mutter eingreift, während das andere Gewinde in der lose gelagerten Spannmutter D eingeschnitten ist. Wird der Stab mit Hilfe des Skalenknopfes gedreht, so verändert sich seine wirksame Länge.Heat regulator with leverage and adjustment device for the control temperature The invention relates to a leverage thermostat in which the Control temperature is adjustable. According to the invention, the control temperature is set by rotating a rod of low thermal expansion that is at its two ends Has threads of different pitch. The subject of the invention is shown in Fig. r to 3 shown and consists of a metal tube A with contact housing, a rod-shaped body B low thermal expansion capacity, a lever C and the with a clearance on the lever C mounted clamping nut D. The rod-shaped body B has threads of different pitches at both ends, one of which goes into an Housing tightly attached nut engages while the other thread in the loose mounted clamping nut D is cut. Is the stick with the help of the scale knob rotated, its effective length changes.

Durch Ausdehnung der Metallröhre A infolge Erwärmung wird der Hebel C, welcher im Bodenstück der Röhre pendelnd gelagert ist, gehoben und dadurch z. B. ein Kontakt E betätigt.When the metal tube A expands as a result of heating, the lever C, which is mounted oscillating in the bottom piece of the tube, lifted and thereby z. B. a contact E is actuated.
