Abstract

Ein mit einer hydraulischen Ausdehnungsdose (5) arbeitender Temperaturregler hat zur Kraftübertragung zwischen der Ausdehnungsdose und der Schaltfeder (21) eines Schnappschalters (20) eine Hebeleinrichtung (30). In diese ist zur Überlastsicherung für die Schaltfeder ein Puffer integriert, der oberhalb einer der Betätigungskraft der Schaltfeder im Schaltpunkt zugeordneten Grenzkraft elastisch nachgiebig und unterhalb der Grenzkraft im wesentlichen starr ist. Die Baueinheit aus Puffer und Hebeleinrichtung wird durch eine in Form eines Blech-Biegeteils vorliegenden Schaltwippe (31) gebildet, die einen L-förmigen Schwenkhebelabschnitt (40) hat, mit dem einstückig eine in Öffnungsrichtung vorgespannte, anschlagsbegrenzt öffnende Bügelfeder (41) ausgebildet ist.

Figure 00000001
A temperature regulator working with a hydraulic expansion socket (5) has a lever device (30) for transmitting force between the expansion socket and the switching spring (21) of a snap switch (20). A buffer is integrated into this for overload protection for the switching spring, which is elastically flexible above a limit force assigned to the actuating force of the switching spring in the switching point and is essentially rigid below the limit force. The unit consisting of a buffer and lever device is formed by a switching rocker (31) in the form of a bent sheet metal part, which has an L-shaped pivoting lever section (40) with which a bow spring (41) that is preloaded in the opening direction and opens to a limit is formed in one piece.
