RollmembranRolling diaphragm
Die Erfindung bezieht sich auf eine aus Gummi oder Kunststoff bestehende Rollmembran, insbesondere für Druckspeicher.The invention relates to a rolling diaphragm made of rubber or plastic, in particular for pressure accumulators.
Bekanntlich müssen Druckspeicher in jeder Einbaulage betriebs- und funktionssicher arbeiten, vorallem bezogen auf eine horizontale Lage der Speicherachse, wenn eine ungleichmäßige Beaufschlagung und damit verbunden ein ungleichmäßiges Abrollen der druckmittelbeaufschlagten Membran eintritt.As is well known, pressure accumulators must work reliably and functionally in every installation position, especially in relation to a horizontal position of the storage axis, if an uneven loading and associated uneven loading Unwinding of the pressurized membrane occurs.
Letzteres hat zur Folge, daß sich im Balg der Rollmembran Palten, Knicke oder Tüten bilden, in deren Bereich durch auftretende Schwingungen um eine statische Mittellage der Membranwerkstoff so lange gewalkt wird, bis das Werkstoffgefüge beschädigt und dadurch porös ist.The latter has the consequence that gaps, kinks or bags are formed in the bellows of the rolling membrane, through which they appear Occurring vibrations around a static middle layer of the membrane material is milled until the material structure damaged and therefore porous.
Der Erfindung liegt die Aufgabe zugrunde, mit baulich und fertigungstechnisch einfachen Mitteln eine wirkungsvolle Ausführung einer Rollmembran zu schaffen, welche diesen Nachteil verhindert und ein gleichmäßiges Ab- und Aufrollen der Membran in jeder Einbaulage des Druckspeichers, auch bei ungleichmäßiger Druckmittelbeaufschlagung gewährleistet.The invention is based on the object of providing an effective one with structurally and technically simple means To create execution of a rolling membrane, which prevents this disadvantage and an even unrolling and rolling up of the membrane in every installation position of the accumulator, including uneven pressure medium admission guaranteed.
Dies geschieht nach der Erfindung dadurch, daß die Rollmembran halbkugelförmig ausgebildet und mit mindestens einer, in einer zu ihrer Mittelachse senkrechten Ebene sich erstreckenden ringförmigen Versteifung versehen ist.This is done according to the invention in that the rolling diaphragm is hemispherical and has at least one is provided in a plane perpendicular to its central axis extending annular stiffener.

Um ein gleichmäßiges Ab- und Aufrollen der Membran zu gewährleisten, weist die Rollmembran zwischen einem äußeren Einspannwulst, einem inneren Befeetigungswulat und der ringförmigen Versteifung eine gleichmäßige Wandstärke auf.In order to ensure that the membrane rolls up and down evenly, the roll membrane has an outer one Einspannwulst, an inner fastening bead and the annular stiffener a uniform wall thickness.
Bei einer Aueführungeform der Erfindung ist die ringförmige Versteifung als Einzelringwulst ausgebildet.In one embodiment of the invention, the one is annular Reinforcement designed as a single ring bead.
Bei einer anderen Ausführungsform der Erfindung ist die ringförmige Versteifung als Mehrfachringwulst ausgebildet.In another embodiment of the invention, the annular stiffener designed as a multiple ring bead.
Ein weiteres Merkmal der Erfindung ist darin zu sehen, daß der Einzel- oder Mehrfachringwulst aus Gummi oder Kunststoff besteht und mit einem oder mehreren Stegen versehen ist.Another feature of the invention is the fact that the single or multiple ring bead made of rubber or plastic exists and is provided with one or more webs.
In weiterer Ausgestaltung der Erfindung ist der Steg für die Befestigung mindestens eines Kunststoffringes mit Drahteinlage ausgebildet als zusätzliche Versteifung und damit zur besseren Führung der Rollmembran.In a further embodiment of the invention, the web for the attachment of at least one plastic ring with a wire insert is designed as an additional reinforcement and thus for better guidance of the rolling diaphragm.
In einer weiteren Ausführung ist der Kunststoffring mit Drahteinlage in abgewickelter Form ausgebildet.In a further embodiment, the plastic ring is with Wire insert formed in a developed form.
Schließlich besteht eine erfindungsgemäße Ausführung darin, daß der Kunststoffring mit Drahteinlage in einer den Steg umfassenden Form ausgebildet ist.Finally, an embodiment according to the invention consists in that the plastic ring with wire inlay in one of the web comprehensive form is formed.
Diese beschriebenen Ausführungen gewährleisten ein betriebs» und funktionssicheres Ab- und Aufrollen der Rollmembran in jeder Einbaulage des flfruckspeichers.These described designs ensure an operationally and functionally reliable unrolling and rolling up of the rolling membrane in every installation position of the pressure accumulator.
In der Zeichnung ist die Erfindung in einer Äusführungsfor» beispielsweise dargestellt.In the drawing, the invention is shown in one embodiment. for example shown.
