Description

Gegenstand der Erfindung ist ein Zylinder für Pressen, Pumpen o. dgl., bei dem der vom Kolben erzeugte Druck nicht nur von innen, sondern auch von außen auf eine den Kolbeii abdichtende Buchse wirkt. Die Buchse wird beim Arbeiten des Kolbens nicht deformiert und hält infolgedessen auch bei Erzeugung sehr hoher Drücke die Abdichtung aufrecht.The invention relates to a cylinder for presses, pumps or the like. In which the dated Pistons generated pressure not only from within, but also from outside on one of the Kolbeii sealing bush acts. The bushing is not deformed when the piston is working and consequently maintains the seal even when very high pressures are generated.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt. In den Zylind'erkörper ι ist eine Buchse 2 eingesetzt, in der der Kolben 3 arbeitet. Zwischen dem Körper 1 und der Buchse 2 besteht ein Hohlraum 5, der mit dem Innern der Buchse in Verbindung steht; durch die Bohrung 4 wird angesaugt und gefördert. Beim Arbeiten des Kolbens 3 wirkt von außen auf die Buchse 2 niemals geringerer Druck als von innen. Infolgedessen kann sich die Buchse 2 nicht ausdehnen, so daß die Dichtung zwischen ihr und dem Kolben 3 einwandfrei aufrechterhalten bleibt. Nachgiebige Manschetten, z. B. aus Leder, wie sie sonst zur Erzielung hoher Drücke verwendet werden müssen, sind entbehrlich. Man kann ganz auf die Manschetten verzichten, kann aber auch Metalimanschetten benutzen, die vor denen aus Leder den Vorteil größerer Beständigkeit haben. Bei der Wahl des Materials für die Buchse 2 braucht auf die Festigkeitseigenschaften keine so große Rücksicht genommen zu werden, wie dies sonst bei Hochdruckpumpen notwendig ist; vielmehr kann in erster Linie chemische Widerstandsfähigkeit und gute Bearbeitbarkeit bestimmend sein.An exemplary embodiment is shown in the drawing. In the cylinder body ι is a bush 2 is used, in which the piston 3 works. Between the body 1 and the Bushing 2 is a cavity 5 which communicates with the interior of the bushing; by the bore 4 is sucked in and promoted. When the piston 3 is working, it acts from the outside never apply less pressure on socket 2 than from the inside. As a result, the Do not expand socket 2, so that the seal between it and piston 3 is satisfactory is maintained. Resilient cuffs, e.g. B. made of leather, as otherwise used to achieve high pressures are dispensable. You can do without the cuffs entirely, but can also use metal cuffs, which have the advantage of being larger than those made of leather Have persistence. When choosing the material for the socket 2 needs to be Strength properties not to be taken into account as much as is otherwise necessary with high-pressure pumps; Rather, primarily chemical resistance and good machinability can be used be decisive.
