For unlubricated compressors piston and piston rod seals are made of non-metallic, single or multiple cut, one or more parts sealing elements used. The disadvantage here is the leakage at the joints of the cut sealing elements, which ultimately leads to restrictions on the flow rate and thermal problems. Solution to the Problem The object of the invention is therefore to provide a method so that the aforementioned disadvantages are avoided. According to the invention this object is achieved by a method having the features of claims 1 and 2. Field of application For cylinder and piston rod sealing of a linear compressor.

Description

Linearverdichter sind Kolbenkompressoren, bei denen die Kolben durch Linearantriebe z. B. Kugel- oder Rollengewindetriebe angetrieben werden.linear compressor are piston compressors, where the pistons by linear drives z. B. ball or roller screws are driven.

Bei ungeschmierten Verdichtern werden Kolben- und Kolbenstangendichtungen aus nichtmetallischen, ein- oder mehrfach geschnittenen, ein- oder mehrteiligen Dichtelementen verwendet.at unlubricated compressors are piston and piston rod seals made of non-metallic, single or multiple cut, one or more parts Used sealing elements.

Nachteilig hierbei sind die Leckverluste an den Stößen der geschnittenen Dichtelemente, was letztendlich zu Einschränkungen der Fördermenge und zu thermischen Problemen führt.adversely In this case, the leakage losses at the joints of the cut sealing elements, which ultimately leads to limitations the flow rate and leads to thermal problems.

Der Erfindung liegt damit die Aufgabe zugrunde, ein Verfahren zu schaffen, so dass die zuvor erwähnten Nachteile vermieden werden.Of the Invention is therefore an object of the invention to provide a method so that the aforementioned Disadvantages are avoided.

Erfindungsgemäß wird diese Aufgabe durch ein Verfahren mit den Merkmalen aus den Patentansprüchen 1 und 2 gelöst.According to the invention this Task by a method having the features of the claims 1 and 2 solved.

Die Erfindung betrifft eine Zylinder- und Kolbenstangenabdichtung von einfach- und/oder doppeltwirkenden Linearverdichtern.The The invention relates to a cylinder and piston rod seal of single- and / or double-acting linear compressors.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus nachfolgender Beschreibung eines bevorzugten Ausführungsbeispiels anhand der beigefügten Zeichnung.Further Features and advantages of the invention will become apparent from the following Description of a preferred embodiment with reference to attached Drawing.

Dabei zeigt:there shows:

I einen Schnitt der erfindungsgemäßen Anordnung von Dichtelementen eines doppeltwirkenden Linearverdichters. I a section of the inventive arrangement of sealing elements of a double-acting linear compressor.

Hierbei handelt es sich um einen Zylinder (01) mit einem Kolben (02), der durch eine Kolbenstange (03) bewegt wird.This is a cylinder ( 01 ) with a piston ( 02 ), which by a piston rod ( 03 ) is moved.

Zur Abdichtung des Kolbens (02) und der Kolbenstange (03) werden geschlossene, durch O-Ringe (04 und 07) vorgespannte Dichtringe (05 und 06) wie in der Pneumatik und Hydraulik verwendet.For sealing the piston ( 02 ) and the piston rod ( 03 ) are closed, by O-rings ( 04 and 07 ) preloaded sealing rings ( 05 and 06 ) as used in pneumatics and hydraulics.

Dies ist durch das Prinzip der geringen Kolbengeschwindigkeit eines Linearverdichters möglich.This is due to the principle of low piston speed of a linear compressor possible.

Aus der Anwendung oben beschriebener Dichtelemente ergeben sich geringere Leckverluste und thermische Belastungen.Out the application of the above-described sealing elements result in less Leakage losses and thermal loads.
