Die Erfindung betrifft eine Flüssigkeitsfeder mit von der Temperatur weitgehend unabhängiger Vorlast durch eine zusätzliche, von dynamisch-hydraulischen Stoßen, unbeeinflußte, nachgeschaltete und von der Flüssigkeitsfeder getrennte Gasfeder, insbesondere zu verwenden für Zug- und Stoßvorrichtungen, nach der Hauptpatentanmeldung V 26031 XII/47a (deutsche Auslegeschrift 1211444).The invention relates to a liquid spring with a preload that is largely independent of the temperature by an additional, downstream and uninfluenced by dynamic hydraulic shocks Gas spring separate from the liquid spring, especially to be used for pulling and pushing devices, according to the main patent application V 26031 XII / 47a (German Auslegeschrift 1211444).
Die vorgeschlagene Flüssigkeitsfeder ist gekennzeichnet durch die Kombination mit einer Gasfeder. Dabei ist der Arbeitsraum der Flüssigkeitsfeder vom Arbeitsraum der Gasfeder durch einen axial beweglichen Freikolben getrennt. Die Bewegung dieses Freikolbens ist durch mechanische Anschläge begrenzt, wobei der zur Gasfeder gehörige Anschlag ein verbleibendes Gasvolumen garantiert. Durch Vorordnung einer Kappillaröffnung ist der Freikolben von dynamisch-hydraulischen Stoßen unbeeinflußt.The proposed liquid spring is characterized by the combination with a gas spring. The working space of the liquid spring is separated from the working space of the gas spring by an axially movable one Free piston separated. The movement of this free piston is limited by mechanical stops, whereby the stop belonging to the gas spring guarantees a remaining gas volume. By pre-order a capillary opening, the free piston is unaffected by dynamic hydraulic shocks.
Die dabei durch den beweglichen Kolben auftretenden, in der Fachwelt allgemein bekannten Nachteile einer dynamischen Dichtung gegenüber einer statischen sollen durch die Erfindung beseitigt werden.The disadvantages that occur due to the movable piston and are generally known in the specialist field a dynamic seal versus a static seal is intended to be eliminated by the invention will.
Dies geschieht dadurch, daß der Arbeitsraum der Gasfeder vom Arbeitsraum der Flüssigkeitsfeder in an sich bekannter Weise durch eine elastische Blase oder Membran getrennt ist und von der Flüssigkeitsfeder über ein druck- oder strömungsabhängiges Ventil beaufschlagt wird.This is done by the working space of the gas spring from the working space of the liquid spring in is separated in a manner known per se by an elastic bladder or membrane and from the liquid spring is acted upon by a pressure- or flow-dependent valve.
An Hand eines in der Zeichnung dargestellten Ausführungsbeispieles soll die Erfindung näher erläutert werden.The invention is to be explained in more detail using an exemplary embodiment shown in the drawing will.
Die Gasfeder als temperaturausgleichende Vorrichtung ist in einem Behälter 7, der am Zylinderende einer Flüssigkeitsfeder 1 dicht eingeschraubt ist, angeordnet. Eine elastische Blase 4 trennt dabei den Arbeitsraum! der Flüssigkeitsfeder 1 vom Arbeitsraum 3 der Gasfeder. Die Blase 4 wird über ein Füllventil 5 mit Gas gefüllt. Weiterhin ist der Blase 4 ein Ventil 6 vorgeordnet, welches druckabhängig betätigt wird.The gas spring as a temperature compensating device is in a container 7 at the end of the cylinder a liquid spring 1 is screwed tightly, arranged. An elastic bladder 4 separates the Working space! the liquid spring 1 from the working area 3 the gas spring. The bladder 4 is filled with gas via a filling valve 5. Furthermore, the Bladder 4 upstream of a valve 6, which is actuated as a function of pressure.
Die durch Temperaturdifferenzen auftretende Volumen- und die damit verbundene Vorlaständerung im entlasteten Zustand der Flüssigkeitsfeder 1 wird durch das Gas im Arbeitsraum 3 bei geöffnetem Ven-Flüssigkeitsfeder mit TemperaturausgleichThe volume change and the associated flow change caused by temperature differences In the unloaded state of the liquid spring 1, the gas in the working space 3 with the Ven liquid spring open with temperature compensation

til 6 ausgeglichen. Beim Einfedern der Flüssigkeitsfeder 1 wird durch den Druckanstieg das Ventil 6 geschlossen, so daß die Blase 4 und damit der Arbeitsraum 3 der Gasfeder vom weiter ansteigenden Flüssigkeitsdruck unbeeinflußt bleiben.til 6 balanced. When the liquid spring 1 is compressed, the pressure increase causes the valve 6 closed, so that the bladder 4 and thus the working space 3 of the gas spring from further increasing Liquid pressure remain unaffected.
