Description

Liegende, doppelt wirkende Hochdruckumfüllpumpe für Handbetrieb, insbesondere zum Umfüllen von Sauerstoff Die Erfindung betrifft eine liegende, doppelt wirkende Hochdruckumfüllpumpe, insbesondere zum Umfüllen von Sauerstoff, bei der der Pumpenrahmen eine Wanne zur Aufnahme des Schmiermittels darstellt.Horizontal, double-acting high pressure transfer pump for manual operation, in particular for transferring oxygen. The invention relates to a horizontal, double-acting High pressure transfer pump, especially for transferring oxygen, in which the pump frame represents a trough for receiving the lubricant.

An sich ist es bekannt, bei Hochdruckumfüllpumpen ein Gehäuse mit einer Ölwanne vorzusehen, die die Schmierung der bewegten Teile übernimmt. Der Antrieb der Kolben erfolgt dabei durch Exzenter, deren Schmierung nur dadurch. möglich ist, daß ein Kulissenring sich in dem Kolbenschlitz auf .und ab bewegt und dadurch als Pumpe wirkt. Durch die zahlreichen bewegten Teile entstehen bei einer derartigen Ausführung verhältnismäßig große Reibungsverluste. Außerdem ist das Reinigen der Zylinder und das Auswechseln der Dichtungsringe umständlich und die Schmierung unvollkommen, obwohl das Exzenter als Pumpe wirkt.It is known per se to have a housing with high-pressure transfer pumps to provide an oil pan, which takes over the lubrication of the moving parts. The drive the piston is carried out by eccentrics, which is only lubricated by this. is possible, that a sliding ring moves up and down in the piston slot and thereby as Pump works. The numerous moving parts result in such a Execution of relatively large frictional losses. Also, cleaning the Cylinder and changing the sealing rings cumbersome and the lubrication incomplete, although the eccentric acts as a pump.

Die Erfindung unterscheidet sich von dem bekannten Vorschlag im wesentlichen dadurch, daß die beiden Zylinder derart an der Wanne angeordnet sind, daß ihre Bohrungen und die von je einer Manschette, gebildeten Abdichtungen der Kolben, deren Durchmesser soviel kleiner als derjenige der Zylinder ist, daß auch deren Wandungen benetzt werden, im Schmiermittel, das zugleich als Kühlmittel wirkt, liegen.The invention differs from the known proposal essentially in that the two cylinders are arranged on the tub that their bores and the seals of the pistons, each formed by a sleeve, their diameter is so much smaller than that of the cylinder that its walls are also wetted will lie in the lubricant, which also acts as a coolant.

Bei einer solchen Ausbildung findet eine wesentlich bessere Schmierung aller Teile statt. Gleichzeitig wird auch Kühlung unter Verzicht auf eine Pumpwirkung verbessert. Das Auswechseln der Dichtungsringe und Reinigen der Zylinder geht leicht und schnell vor sich.With such a training, there is much better lubrication of all parts. At the same time, there is also cooling, dispensing with a pumping effect improved. Changing the sealing rings and cleaning the cylinders is easy and quickly in front of you.

Bei einer bevorzugten Ausführungsform der Erfindung wird das Auswechseln der Dichtungsringe dadurch in besonders e einfacher Weise erreicht, daß die beiden -als Kolbendichtung dienenden Manschetten am inneren Ring durch eine Mutter gehalten werden.In a preferred embodiment of the invention, the replacement the sealing rings thereby achieved in a particularly simple manner that the two -Cuffs, which serve as piston seals, are held on the inner ring by a nut will.

Zum Auswechseln der Manschetten sind lediglich die beiden Schrauben zu lösen, die die Kolben im Kreuzkopf festhalten. Dann wird die die Hebelgabel stützende Achse her- atlzl''eilciliililcü, und die Kolben werden etwas in die Zvlinder himin-edriickt. Nach dein I?ntfern @n der Hebelgabel und t@@egtialitiie des Krtnzkopfes Uinnen alsdann die halben leicht licralisguzagcn werilcil.
