Abstract
Dehnstoffelement mit einem Gehäuse (14) und einem elektrischen Widerstandselement, das im Inneren des Gehäuses (14) auf einem Träger (2) angeordnet ist, wobei der Träger (2) eine Öffnung des Gehäuses (14) verschließt und die Gehäuseinnenseite und ein am Träger (2) ausgebildeter Sockel (4) einen angepassten Ringabsatz (16) aufweisen, der den Innendruck aufnimmt, dadurch gekennzeichnet, dass ein Kleber (22) zwischen Gehäuseinnenseite und Träger (2) an der dem Innenraum (24) abgewandten Seite des Ringabsatzes (16) aufgebracht ist.Expanding element with a housing (14) and an electrical resistance element, which is arranged inside the housing (14) on a support (2), wherein the carrier (2) closes an opening of the housing (14) and the inside of the housing and one on the support (2) formed base (4) have an adapted annular shoulder (16) which receives the internal pressure, characterized in that an adhesive (22) between the inside of the housing and support (2) on the interior (24) facing away from the side of the annular shoulder (16 ) is applied.
Description
Die Erfindung betrifft ein Dehnstoffelement, insbesondere zur Betätigung eines Thermostatventils, mit einem Gehäuse und mit einem aus dem Gehäuse herausgeführten beweglichen Arbeitsstift, wobei in dem Gehäuse Dehnstoff und eine Heizeinrichtung mit einem auf einem Träger angebrachten elektrischen Widerstandselement angeordnet sind.The invention relates to an expansion element, in particular for actuating a thermostatic valve, with a housing and with a guided out of the housing movable working pin, wherein in the housing expansion material and a heater are arranged with a mounted on a support electrical resistance element.
Die
Darin ist ein Träger beschrieben, der einen Spulenkörper zum Aufwickeln eines Heizdrahtes und einen Sockel aufweist, dessen Durchmesser in etwa dem Innendurchmesser des Gehäuseunterteils entspricht. In einer Ausgestaltungsvariante entsprechend
Nachteilig bei der Ausgestaltung des Sockels entsprechend
Die Aufgabe wird durch ein Dehnstoffelement mit den im Anspruch 1 angegebenen Merkmalen gelöst.The object is achieved by an expansion element with the features specified in claim 1.
Bevorzugt werden hierbei Kleber mit einer Scherfestigkeit von mindestens 20 N/mm2, insbesondere Epoxidharzkleber, äußerst bevorzugt 1-Komponenten-Epoxidharzkleber. Denkbar sind aber auch andere Kleber, welche die Anforderungen an Wärmebeständigkeit und Mediumsbeständigkeit erfüllen.In this case, adhesives having a shear strength of at least 20 N / mm 2 , in particular epoxy resin adhesive, very preferably 1-component epoxy resin adhesive are preferred. Conceivable, however, are other adhesives that meet the requirements of heat resistance and medium resistance.
Bevorzugt ist weiterhin, den Kleber außerhalb des vom O-Ring abgedichteten Innenraumes zwischen Sockel und Gehäuse aufzubringen. Dadurch erfolgt eine Druckentlastung des Sockels im Bereich des Ringabsatzes, der äußere Ringansatz wird druckentlastet und hält einem höheren Innendruck stand. Vorteilhaft ist so auch keine Dehnstoffbeständigkeit des Klebers erforderlich.Furthermore, it is preferable to apply the adhesive outside of the inner space sealed by the O-ring between the base and the housing. This results in a pressure relief of the base in the region of the annular shoulder, the outer annular shoulder is depressurized and withstands a higher internal pressure. Advantageously, no expansion resistance of the adhesive is required.
Denkbar wäre aber auch, auf die O-Ring-Dichtung und die dadurch erforderliche Ringnut zu verzichten und nur noch einen Kleber zwischen dem Sockel und dem Gehäuse aufzubringen.It would also be conceivable to dispense with the O-ring seal and the required annular groove and apply only an adhesive between the base and the housing.
Weitere Vorteile und Merkmale sind den Fig. und den Beschreibungen hierzu zu entnehmen.Further advantages and features are shown in FIGS. And the descriptions thereof.
