Description

Die Erfindung betrifft ein Verfahren zur Herstellung von Flüssigkeiten, insbesondere für hydraulische Stoßdämpfer.The invention relates to a method for producing liquids, in particular for hydraulic shock absorbers.

Wie bekannt, hängt die Wirksamkeit eines hydraulischen Stoßdämpfers im wesentlichen von demjenigen Widerstände ab, welchen die durch kleine Durchtrittsquerschnitte hindurchtretende nicht komprimierbare Flüssigkeit entwickelt.As is known, the effectiveness of a hydraulic shock absorber depends essentially from those resistances, which the passing through small passage cross-sections developed incompressible liquid.

Daraus geht hervor, daß, gleichgültig, ob der Stoßdämpfer mit Drehschaufeln oder mit einem Kolben arbeitet, die Flüssigkeit selbst einen wesentlichen Einfluß auf die Wirksamkeit des Stoßdämpfers ausübt.
Gewöhnlich wird in Stoßdämpfern dieser Art Rizinusöl verwendet, weil dieses die mit ihm in Berührung kommenden Teile gleichzeitig gut schmiert und außerdem gewisse Vorteile infolge seiner besonderen Viskosiao tätseigenschaften bietet. Das Öl hat jedoch die unangenehme Eigenschaft, selbst durch feinste Spalten herauszukriechen. Die Zurückhaltung einer solchen Flüssigkeit im Stoßdämpfer ist daher eine schwierig zu lösende Aufgabe, da jeder Stoffverlust die Wirksamkeit des Stoßdämpfers in empfindlicher Weise beeinträchtigt. Ferner unterliegt das öl der Einwirkung der Oxydation. Mit der vorliegenden Erfindung werden diese Nachteile beseitigt.It can be seen from this that, regardless of whether the shock absorber operates with rotating vanes or with a piston, the liquid itself has a significant influence on the effectiveness of the shock absorber.
Castor oil is usually used in shock absorbers of this type because this lubricates the parts that come into contact with it at the same time and also offers certain advantages due to its special viscosity properties. However, the oil has the unpleasant property of creeping out even through the finest crevices. The retention of such a liquid in the shock absorber is therefore a difficult task to be achieved, since any loss of material affects the effectiveness of the shock absorber in a sensitive manner. Furthermore, the oil is subject to oxidation. The present invention overcomes these disadvantages.

Gemäß der Erfindung soll nämlich als Füllmaterial für Stoßdämpfer eine Emulsion von öl in Wasser dienen. Weitere Verbesserung besteht in der Verwendung von Chemikalien zur Herabsetzung des Gefrierpunktes dieser Emulsion.According to the invention, namely, as a filling material for shock absorbers, an emulsion of serve oil in water. Another improvement is the use of chemicals to lower the freezing point of this emulsion.

Beispielsweise besteht eine geeignete Flüssigkeit aus folgenden Bestandteilen:For example, a suitable liquid consists of the following components:

Wasser 45,11,Water 45.11,

reines Öl aus Schweinefett.... 11,4I1 pure oil from pork fat .... 11.4I 1

Soda 3,1 kg,Soda 3.1 kg,

Schmierseife 0,9 kg.Soft soap 0.9 kg.

Die Emulsion wird folgendermaßen hergestellt: Soda und Seife werden in Wasser aufgelöst und darauf das öl zugegeben, worauf das ganze Gemisch in eine Emulgiertrommel gegeben wird.The emulsion is made as follows: Soda and soap are dissolved in water and then the oil is added, whereupon the whole mixture is poured into an emulsifying drum is given.

Ein anderes ebenfalls gut geeignetes Füllmittel wird aus folgenden Bestandteilen hergestellt: Another equally well-suited filler is made from the following ingredients:

Handelsolein 3 bis 5 Teile,Commercial oil 3 to 5 parts,

Methylalkohol 1 Teil,Methyl alcohol 1 part,

Mineralöl 0,885 X9 Teile,Mineral oil 0.885 X 9 parts,

Glyzerin 1 Teil,Glycerine 1 part,

Kaliumhydroxyd 1 Teil, Potassium hydroxide 1 part,

Wasser , 75 Teile.Water, 75 parts.

Olein und Methylalkohol werden zuerst miteinander in kaltem Zustande gemischt undOlein and methyl alcohol are first mixed with each other in the cold state and

darauf das Mineralöl langsam zugefügt. Das Glyzerin, Kaliumhydrat und Wasser werden ebenfalls, zweckmäßig in einer Emulgiereänrichrung, miteinander gemischt, und darauf wird die erste Mischung zugefügt, und es wird Y2 Stunde emulgxert. Ein Farbstoff wird dem Mineralöl oder der Emulsion zugegeben. then slowly added the mineral oil. The glycerine, potassium hydrate and water are also mixed with one another, expediently in an emulsifying device, and then the first mixture is added and emulsified for 2 hours. A color is added to the mineral oil or emulsion.

An Stelle der oben angegebenen EmulsionInstead of the emulsion given above

ίο können andere Emulsionen Verwendung finden, insbesondere aus anderen ölen, obwohl besonders die zweite Emulsion infolge ihres tiefen Gefrierpunktes vorteilhaft ist.ίο other emulsions can be used, especially from other oils, although especially the second emulsion because of their low freezing point is beneficial.

Der Hauptvorteil, welcher durch die neuen Füllstoffe erzielt wird, besteht in der Möglichkeit, diese durch Stopfbüchsen in dem Stoßdämpfer zurückzuhalten, im Gegensatz zum reinen öl, welches stets das Bestreben hat, durch die allerfeinsten öffnungen herauszukriechen. · Außerdem schmieren diese Füllstoffe die Oberflächen der beweglichen Teile wie ein selbsttätiges Schmiermittel, haften aber an diesen Teilen nicht an, da sie sie nicht benetzen, sondern von ihnen ablaufen.The main advantage achieved by the new fillers is the ability to to hold them back in the shock absorber by means of stuffing boxes, in contrast to the pure oil, which always strives to crawl out through the finest openings. · In addition, these fillers lubricate the surfaces of moving parts like an automatic lubricant that adhere but not on these parts because they do not wet them, but run off them.

Die neuen Füllmittel sind relativ dünnflüssig und mehr wasserähnlich im Vergleich zu dem üblicherweise verwendeten öl. Es können noch besondere, den Gefrierpunkt herabsetzende Stoffe hinzugefügt werden, nachdem die Emulsion fertiggestellt wurde.The new fillers are relatively thin and more like water in comparison to the commonly used oil. There can be special ones that lower the freezing point Substances are added after the emulsion has been completed.

Die neuen Füllmittel werden in Stoßdämpfern durcü die gewöhnlichen Ledermanscbetten leicht zurückgehalten, wenn solche für Stopfbüchsen verwendet werden.The new fillers are used in shock absorbers through the ordinary leather mancases easily retained when used for stuffing boxes.
