Abstract
Description
Die Erfindung betrifft einen Druckmittelspeicher mit einem Gehäuse, dessen Innenraum durch ein Medientrennungselement in zwei Kammern unterteilt ist, wobei die erste Kammer mit einem Gas und die zweite Kammer mit Druckmittel gefüllt ist und wobei das Medientrennungselement aus einem metallischen Faltenbalg besteht, der aus miteinander verbundenen, im Querschnitt wellenförmig ausgebildeten Ringen gebildet ist und der mit einem Deckel und einem Boden verschlossen ist.The invention relates to a pressure medium accumulator with a housing, its interior by a media separation element in two chambers is divided, the first chamber with a gas and the second Chamber filled with pressure medium is and wherein the media separation element made of a metallic Bellows consists of interconnected, in cross section wavy trained rings is formed and with a lid and a Bottom is closed.
Ein derartiger Druckmittelspeicher,
der als Medienrennungselement einen aus im Querschnitt wellenförmig ausgebildeten
Ringen gebildeten Faltenbalg vorsieht, ist aus der internationalen
Patentanmeldung
Es ist daher Aufgabe der vorliegenden Erfindung einen Druckmittelspeicher der eingangs genannten Gattung dahingehend zu verbessern, dass eine Beschädigung des Faltenbalgs aufgrund mechanischer Belastungen verhindert wird und somit eine er hebliche Erhöhung der Funktionssicherheit gewährleistet wird.It is therefore the task of the present Invention a pressure medium storage of the type mentioned to improve in that damage to the bellows due to mechanical loads is prevented and therefore he considerable increase guaranteed functional reliability becomes.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die dem Faltenbalg zugewandte Oberfläche des Bodens derart ausgebildet ist, dass der letzte Ring des Faltenbalgs in Richtung des Bodens spaltfrei am Boden anliegt.This object is achieved according to the invention solved, that the surface of the bottom facing the bellows is formed in such a way is that the last ring of the bellows towards the bottom lies on the floor without gaps.
Eine vorteilhafte Ausführungsform sieht vor, dass die dem Faltenbalg zugewandte Oberfläche des Deckels derart ausgebildet ist, dass der letzte Ring des Faltenbalgs in Richtung des Deckels spaltfrei am Deckel anliegt. Durch diese Maßnahmen wird die mechanische Belastung des Faltenbalgs während einer vollständigen Komprimierung reduziert.An advantageous embodiment provides that the surface of the cover facing the bellows is designed such that the last ring of the bellows in In the direction of the lid there is no gap in the lid. Through these measures is the mechanical stress on the bellows during full compression reduced.
Außerdem weist der jeweils letzte Ring des Faltenbalgs in Richtung des Deckels oder des Bodens einen axialen Kragen auf, der mit dem Deckel und dem Boden verbunden ist, wobei der jeweils letzte Ring des Faltenbalgs in Richtung des Deckels oder des Bodens wellenförmig ausgebildet ist.In addition, the last one shows Bellows ring towards the lid or bottom one axial collar, which is connected to the lid and the bottom, the last ring of the bellows in the direction of the cover or the bottom is wavy is trained.
Eine besonders vorteilhafte Ausführungsform sieht vor, dass der Boden eine seitliche Führung für den Faltenbalg während eines extremalen Befüllungszustandes des Druckmittelspeichers darstellt.A particularly advantageous embodiment provides that the bottom provides a lateral guide for the bellows during a extreme filling condition of the pressure fluid reservoir.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels im Zusammenhang mit der beiliegenden Zeichnung näher erläutert. In der Zeichnung zeigen:The invention is described below of an embodiment explained in connection with the accompanying drawing. The drawing shows:
