Description

Beschreibung Neuartige Dichtgrenzen an Verdichtern, Pumpen, Dreh- oder Kreiskolbenmaschinen, Gasmotoren, Hydromotoren u.s.w.Description New sealing limits on compressors, pumps, rotary or rotary piston machines, gas engines, hydraulic motors, etc.

Gegenstand der Erfindung ist eine neuartige Gestaltung der Dichtgrenzen bei Maschinen, die mit kreisenden oder umlaufenden Kolben oder Verdrängern oder Schiebern arbeiten. Es ist gleich, ob vermittels dieser Maschinen eine mechanische Leistung in Druck oder Vakuum umgesetzt wird, oder ob der entgegengesetzte Vorgang stattfindet.The subject of the invention is a novel design of the sealing boundaries for machines with rotating or revolving pistons or displacers or Sliders work. It does not matter whether these machines are used to create a mechanical one Power is converted into pressure or vacuum, or whether the opposite process takes place.

Bekannt sind vorgenannte Maschinen, bei denen die Strinflächen der Kolben oder Verdränger und die dazugehörigen Gehäuseteile gerade sind. In Abbildung 1 und 2 ist diese bekannte Ausführung an dem Beispiel einer Zahnradpumpe gezeigt.The aforementioned machines are known in which the Strinflächen the Piston or displacer and the associated housing parts are straight. In figure 1 and 2, this known embodiment is shown using the example of a gear pump.

Der Nachteil dieser Ausführung besteht darin, dass# die Abdichtung an den Stirnflächen für dünne Medien, wie z. B. Luft oder Gas, sehr schwierig ist. Die Spaltverluste sind gross. Die Schmierung ist problematisch.The disadvantage of this design is that # the seal at the end faces for thin media, such as B. air or gas, is very difficult. The gap losses are great. Lubrication is problematic.

Die Neuerung besteht nun darin, dass die Kolben oder Verdränger an den Stirnflächen halbkreisförmig gestaltet werden. Die Gehäuse erhalten ebenfalls diese Form. Abbildung 3 zeigt ein Ausführungsbeispiel für eine Zahnradpumpe.The innovation now consists in the fact that the piston or displacer is attached the end faces are designed to be semicircular. The enclosures also received this form. Figure 3 shows an embodiment for a gear pump.

Die Vorteile dieser Ausführung sind Klar: Die Kolben oder Verdränger können mit Kolbenringen versehen werden, wie es bei Maschinen mit Zylindern und zylindrischen Kolben der Fall ist. Die halbkreisförmigen Kolbenringe können am Kolben Halt bekommen durch besondere Formgebung. Sie können Nasen besitzen, die in den Kolben greifen, oder nahe der Enden der Kolbenringe können Nuten sein durch welche andere Ringe führen und Halt geben. Die Kolbenringe und die Kolbennuten können auch durch ein besonderes Profil miteinander verbunden werden.The advantages of this design are clear: the pistons or displacers can be fitted with piston rings, as is the case with machines with cylinders and cylindrical piston is the case. The semicircular piston rings can be attached to the piston Get hold of the special shape. They may have noses that are in the Pistons grip, or near the ends of the piston rings there may be grooves through which guide other rings and provide support. The piston rings and the piston grooves can also be connected to each other by a special profile.

Durch die Kolbenringe können die Spaltverluste vermieden oder stark reduziert werden.The gap losses can be avoided or increased by the piston rings be reduced.

Wenn die Maschinen mit heissen oder kalten gasförmigen Medien arbeiten, kann ein Schmiermittel - z. B. Öl - durch das Gehäuse oder den Kolben zu den aneinander gleitenden Stellen geleitet werden. Dieses Schmiermittel kann auch zum Teil von Abstreifringen wieder aufgenommen und abgeführt werden.If the machines work with hot or cold gaseous media, can be a lubricant - e.g. B. Oil - through the housing or the piston to the one another sliding positions. This lubricant can also be used in part Wiper rings are picked up again and removed.
