Description
Die Erfindung betrifft ein Dehnstoffelement nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to an expansion element according to the preamble of Patent claim 1.
Aus
der
Aufgabe der Erfindung ist es, ein einfaches und kostengünstiges Dehnstoffelement zu schaffen, welches im Wesentlichen eine verbesserte Axial- und Radialführung einer mittels Dehnstoff betätigbaren Kolbenstange gestattet.task The invention is a simple and inexpensive To provide expansion element, which substantially improved Axial and radial guidance of an expandable piston rod allowed.
Ausgehend von einem Dehnstoffelement, umfassend ein Gehäuse, in welchem Dehnstoff angeordnet ist, sowie eine federbelastete Kolbenstange, die ihrerseits infolge einer bestimmten Medientemperatur bewirkten Volumenänderung des Dehnstoffes relativ zum Gehäuse gegen die Federkraft „FFeder" verschiebbar ist, wird die gestellte Aufgabe dadurch gelöst, dass der Dehnstoff von einem im Wesentlichen aus einer elastischen Membran gebildeten ringförmigen Beutel aufgenommen ist, der seinerseits innerhalb des Gehäuses angeordnet und durch seine zentrische Öffnung hindurch von der Kolbenstange durchdrungen ist, wobei der mit Dehnstoff gefüllte Beutel in Bewegungsrichtung der Kolbenstange gesehen, einenends axial an einem Radialsteg der Kolbenstange und anderenends axial am Gehäuse abgestützt ist. Gemäß einer besonders vorteilhaften Ausgestaltung der Erfindung ist der mit Dehnstoff gefüllte Beutel derart ausgebildet, dass in jedweden Betriebszustand des Dehnstoffelementes durch den Beutel zum einen über die Länge desselben eine weitestgehend vollumfängliche radiale Abstützung der Kolbenstange und/oder zum anderen eine weitestgehend vollumfängliche axiale Abstützung des Radialsteges der Kolbenstange gewährleistet ist. In weiterer Ausgestaltung der Erfindung kann der den Dehnstoff aufnehmende Beutel durch ein ringförmiges, weitestgehend starres stirnseitiges Deckelelement des Gehäuses sowie eine an demselben form-, kraft- und/oder stoffschlüssig befestigte ringförmig ausgebildete elastische Membran gebildet sein. Demgegenüber kann der den Dehnstoff aufnehmende Beutel auch ausschließlich durch die elastische Membran gebildet sein. Wie die Erfindung weiter vorsieht, kann der den Dehnstoff aufnehmende Beutel als separates und bereits vormontiertes Ein- oder Anbauteil ausgebildet sein. Vorzugsweise ist besagter Dehnstoff durch ein Wachs, ein Gas oder eine Flüssigkeit gebildet, welche/s bei Erwärmung eine Volumenänderung zum höheren und bei Abkühlung eine Volumenänderung zum niederen aufweist. Wie die Erfindung noch vorsieht, ist das die Federkraft „FFeder" auf die Kolbenstange aufbringende Federelement derart angeordnet, dass eine direkte Berührung mit dem temperaturbestimmenden Medium vermieden ist. Besonders vorteilhaft kann das Dehnstoffelement als ein in Abhängigkeit von einer aktuellen und auf den Dehnstoff des Dehnstoffelementes einwirkenden Medientemperatur selbstregelnder Stellantrieb ausgebildet sein. Insoweit sind durch die Erfindung eine Kühlmittelpumpe im Kühlkreislauf einer Verbrennungskraftmaschine mit dem in Rede stehenden Dehnstoffelement zur Regelung des Volumenstromes eines Kühlmittels in Abhängigkeit von der aktuellen Temperatur desselben sowie ein Ventil mit diesem Dehnstoffelement zur Regelung des Volumenstromes eines gasförmigen oder flüssigen Mediums durch Öffnen oder Schließen des Ventils in Abhängigkeit von der aktuellen Temperatur des besagten Mediums mit erfasst. Ebenso ist durch die Erfindung eine temperaturgesteuerte Kupplung mit einem Dehnstoffelement der oben beschrieben Art als Betätigungsorgan für die Kupplung mit erfasst, wobei die Kupplung als Schaltkupplung oder auch als Fluidkupplung ausgebildet sein kannStarting from an expansion element, comprising a housing in which expansion material is arranged, as well as a spring-loaded piston rod, which in turn due to a certain media temperature caused volume change of the expansion material relative to the housing against the spring force "F spring " is displaced, the object is achieved by in that the expansion material is accommodated by an annular bag essentially formed of an elastic membrane, which in turn is arranged inside the housing and penetrated through its centric opening by the piston rod, the bag filled with expansion material, seen axially in the direction of movement of the piston rod According to a particularly advantageous embodiment of the invention, the pouch filled with expanding material is designed such that in any operating state of the expansion element by means of the Be utel on the one hand over the length of a largely full radial support of the piston rod and / or on the other a largely full axial support of the radial web of the piston rod is guaranteed. In a further embodiment of the invention, the bag receiving the expansion material can be formed by an annular, largely rigid end-face cover element of the housing as well as a ring-shaped elastic membrane fastened to the same in a form-fitting, force-fitting and / or cohesive manner. In contrast, the absorbent material receiving bag may also be formed exclusively by the elastic membrane. As the invention further provides, the absorbent material receiving bag may be formed as a separate and pre-assembled single or attachment. Preferably, said expanding agent is constituted by a wax, a gas or a liquid, which has a volume change to the higher when heated and a volume change to the lower when cooled. As the invention still envisages, the spring element "F spring " is arranged on the piston rod in such a way that direct contact with the temperature-determining medium is avoided In that regard, the invention provides a coolant pump in the cooling circuit of an internal combustion engine with the expansion element in question for controlling the volume flow of a coolant as a function of the current temperature thereof and a valve with this expansion element for controlling the volume flow of a gaseous or liquid medium by opening or closing the valve in Abhän measured by the current temperature of said medium. Likewise, the invention detects a temperature-controlled coupling with an expansion element of the type described above as an actuator for the clutch, wherein the clutch may be formed as a clutch or as a fluid coupling
Das vorgeschlagene Dehnstoffelement hat im Hinblick auf herkömmliche den wesentlichen Vorteil, dass die Axial- und Radialführung der zu betätigenden Kolbenstange desselben durch eine einfache und kostengünstige Maßnahme erheblich verbessert ist, indem der im Beutel abgefüllte Dehnstoff selbst Lager- und Führungsfunktionen übernimmt demgemäß sind aufwendige Lager- und/oder Führungselemente für die Kolbenstange außerhalb des Gehäuses des Dehnstoffelementes entbehrlich, zumindest jedoch reduzierbar.The proposed expansion element has in view of conventional the main advantage that the axial and radial guidance the same to be actuated piston rod by a simple and cost-effective measure is significantly improved, because the expansion material filled in the bag itself and leadership functions are accordingly complex bearing and / or guide elements for the piston rod outside the housing of the expansion element dispensable, but at least reducible.
