Abstract

Um für ein thermisches Auslöseelement für ein thermisches Schaltelement in Form eines eine langgestreckte Form aufweisenden Glasfässchens (1) mit einem vollständig umschlossenen, mit einer Auslöseflüssigkeit unter Einschluss einer Gasblase gefüllten Innenraum, wobei das Glasfässchen (1) entlang seiner Längsrichtung einander gegenüberliegend ein erstes Langsende (2) mit einer aus einem umlaufenden Rand, insbesondere einer umlaufenden Verdickung, hervorgehenden Spitze (4) und ein zweites Längsende (5) mit einem gerundeten bauchigen Abschluss (6) aufweist, eine Möglichkeit zu geben, ohne die Zudosierung von Fett oder Öl im Montageprozess verbesserte Glasfässchen als thermische Auslöseelemente im Aufbau des thermischen Schaltelementes einzusetzen, bei denen beim Einschrauben des Widerlagers dennoch ein gegenüber einem herkömmlichen ohne Öl oder Fett ablaufenden Prozess deutlich verringertes Torsionsmoment in das Glasfässchen eingebracht wird wird vorgeschlagen, dass das Glasfässchen (1) an wenigstens an dem zweiten Längsende (5) reibungsvermindernd behandelt worden ist.

For a thermal triggering element for a thermal switching element in the form of an elongated glass bottle (1) with a completely enclosed interior space filled with a triggering liquid including a gas bubble, the glass vessel (1) along its longitudinal direction opposite one another 2) with a tip (4) emerging from a peripheral edge, in particular a peripheral thickening, and a second longitudinal end (5) with a rounded bulbous end (6), to give a possibility without the addition of fat or oil in the assembly process improved glass kegs are used as thermal tripping elements in the structure of the thermal switching element, in which when screwing the abutment still a relation to a conventional running without oil or fat process significantly reduced torsional moment is introduced into the glass keg is proposed that the Glass keg (1) has been treated at least at the second longitudinal end (5) friction reducing.
