Die Erfindung betrifft ein Verfahren zum Herstellen einer Blase für Druckspeicher, zur Aufnahme eines, insbesondere kompressiblen Druckmittels, aus einem durch eine Haut aus elastomerem Werkstoff umhüllten Füllkörper aus porösem, elastomerem Werkstoff, der an einem Ende einen Ventilkörper aufweist, insbesondere für Druckmittelbehälter oder Stoßdämpfer.The invention relates to a method for producing a bladder for pressure accumulators for receiving a pressure medium, in particular a compressible one, made of an elastomeric material through a skin enveloped filler body made of porous, elastomeric material, which has a valve body at one end has, in particular for pressure medium tanks or shock absorbers.
Eine bekannte Gattung dieser Geräte besteht aus einem starren Behälter, einer den Behälterraum in einen Flüssigkeitsraum und einen Gasraum unterteilenden Blase — wobei der Gasraum von der Blase selbst gebildet wird — und je einem dem Flüssigkeitsraum und dem Gasraum zugeordneten Ventil. Nach dem Zusammenbau des Behälters wird die Blase über das ihr zugeordnete Ventil mit Gas häufig sehr hohen Druckes aufgeblasen; sie legt sich dann allseitig an die Behälterwand an und preßt das Schließglied des dem Flüssigkeitsraum zugeordnten Ventils auf seinen Sitz. Im Betrieb wird ein Druckmittel, sei es zum Speichern von Druckflüssigkeit, sei es zum Auffangen von Druckstößen, über dieses Ventil in den Behälter gepreßt, wobei die Blase zunehmend zusammengedrückt wird. Dabei kann die Haut der sich zusammenziehenden, labilen Blase Falten bilden und knikken, was nach häufigem Wiederholen — wie es im Betrieb der Fall ist — zu Rissen und damit zur Zerstörung der Blase führen kann.A known type of these devices consists of a rigid container, one in the container space a liquid space and a bladder dividing a gas space - the gas space being separated from the bladder itself is formed - and one valve each assigned to the liquid space and the gas space. To When the container is assembled, the bladder often becomes very high with gas via the valve assigned to it Pressure inflated; it then rests against the container wall on all sides and presses the closing member of the the valve assigned to the liquid space on its seat. In operation, a pressure medium, be it for Storage of hydraulic fluid, be it to absorb pressure surges, via this valve into the container pressed, the bladder being increasingly compressed. The skin of the contracting, unstable bladder wrinkles and kinks, what after frequent repetition - like it im Operation is the case - can lead to cracks and thus to the destruction of the bladder.
Es ist bekannt, einen Teil des Blasenvolumens mit einem schwammartigen Füllkörper, ζ. B. aus Schaumgummi oder Schaumstoff, zu füllen. Diese Lösung hat jedoch den Nachteil, daß die Blase beim Zusammenziehen und bis zu dem Zeitpunkt, an dem sie am Füllkörper anliegt, ebenfalls noch gefährliche Falten und Knicke bilden kann. Außerdem ist es sehr umständlich, einen Füllkörper durch die enge Blasenöffnung einzuführen, der dann eine — was ebenfalls notwendig ist — bestimmte Form und Steifigkeit aufweisen soll.It is known to fill part of the bladder volume with a spongy filler, ζ. B. made of foam rubber or foam to fill. However, this solution has the disadvantage that the bladder when contracting and up to the point in time at which it is in contact with the packing, also dangerous Can form folds and creases. In addition, it is very cumbersome to put a packing through the narrow bubble opening to introduce, which then - which is also necessary - have a certain shape and rigidity target.
Es ist auch bekannt, das Volumen einer Blase vollständig mit einem schaumstoffartigen Füllkörper auszufüllen,
wodurch Falten- und Knickbildung weitgehend vermieden werden. Im einen Fall wird der
Füllkörper vorgeformt und in die Blase eingeführt. Bei Blasen mit enger Einführöffnung ist dies, wie
bereits genannt, sehr schwierig. In einem anderen Fall wird der Schaumstoff direkt in die Blase eingespritzt,
insbesondere gleichzeitig mit einem Druckgas, um eine gewisse Vorspannung der Blase zu erlangen.
Dazu ist es allerdings nötig, die Blase vor dem Einspritzen des Füllkörpers in den Behälter einzusetzen
und diesen dicht abzuschließen. Dies ist ziem-Verfahren zum Herstellen einer Blase für
DruckspeicherIt is also known to completely fill the volume of a bladder with a foam-like filling body, as a result of which the formation of folds and kinks is largely avoided. In one case, the packing is preformed and inserted into the bladder. As already mentioned, this is very difficult in the case of bladders with a narrow insertion opening. In another case, the foam is injected directly into the bladder, in particular at the same time as a pressurized gas, in order to achieve a certain pre-tensioning of the bladder. To do this, however, it is necessary to insert the bladder into the container before the filling body is injected and to seal it off tightly. This is quite a method of making a bladder for

lieh umständlich, und es ist dann auch nicht mehr möglich, die Blase auf eventuell beim Einspritzen des Schaumstoffs entstandene Beschädigungen hin zu untersuchen. Auch sind diese Blasen kaum für Höchstdruck-Energiespeicher geeignet, da keine eigentlichen Gaszuführungen zum Blaseninneren (wichtig für das Nachfüllen der Blase) vorhanden sind, außerdem keine Vorkehrungen getroffen sind, damit eingepreßtes Gas das Blasenvolumen gleichmäßig ausfüllt. Weiter ist es nicht möglich, dem Füllkörper eine besondere, vom Blaseninnenraum abweichende Form zu geben oder mit ihm besondere Teile zu verbinden.borrowed awkward, and it is then no longer possible to open the bladder when injecting the To examine any damage caused by the foam. Also, these bubbles are hardly for High-pressure energy storage suitable as there are no actual gas feeds to the interior of the bladder (important for refilling the bladder) are available, and no precautions have been taken thus injected gas fills the bubble volume evenly. Next it is not possible to use the packing to give a special shape deviating from the interior of the bladder or with it a special shape Connect parts.
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Blase, insbesondere auch für Hochdruck-Energiebehälter, zu schaffen, die betriebssicher und einfach herzustellen ist.The invention is therefore based on the object of providing a bladder, in particular also for high-pressure energy containers, to create that is reliable and easy to manufacture.
Dies wird erfindungsgemäß dadurch erreicht, daß der Füllkörper zum Erzeugen der umhüllenden Haut in eine Lösung aus dem elastomeren Werkstoff getaucht wird.This is achieved according to the invention in that the filling body for producing the enveloping skin is immersed in a solution of the elastomeric material.
Die Herstellung ist somit denkbar einfach. Über den vorgeformten Füllkörper wird durch Tauchen in den flüssigen Werkstoff eine Haut erzeugt, die die Blasenhaut bildet. Der Füllkörper braucht nicht mehr umständlich in die Blase eingebracht zu werden; er ist außerdem fest mit deren Haut verbunden.The production is therefore very easy. The preformed packing is dipped in the liquid material creates a skin that forms the skin of the bladder. The packing does not need any more awkward to be introduced into the bladder; it is also firmly attached to their skin.
Vorteilhafterweise wird vor dem Tauchen der Fuß des Ventilkörpers in den Füllkörper eingebettet.The base of the valve body is advantageously embedded in the filler body before the immersion.
An einem Ausführungsbeispiel wird das Verfahren erläutert. Die Zeichnung zeigt einen Längsschnitt durch einen Druckspeicher mit der Blase.The method is explained using an exemplary embodiment. The drawing shows a longitudinal section through an accumulator with the bladder.
