Abstract
Description
Die Erfindung betrifft eine Dichtung mit den Merkmalen des Oberbegriffs des Anspruchs 1.The The invention relates to a seal having the features of the preamble of claim 1.
Aus
der
Weiterhin sind aus dem „Simrit”-Katalog von der Firma Freudenberg Nutdichtringe bekannt, die bei Standard-Zylindern in Spritzgießmaschinen oder Flurförderfahrzeugen eingesetzt werden, die zur Vermeidung von Schmutzeintrag auf die jeweilige Lauffläche des Kolbens eine angeformte Abstreiflippe aufweisen. Diese Nutdichtringe werden beispielsweise als Sekundärdichtung in einem Geberzylinder eingesetzt, der Teil einer hydraulischen Strecke ist.Farther are from the "Simrit" catalog by Freudenberg Grooved seals known in standard cylinders in injection molding machines or industrial trucks are used to avoid of dirt on the respective running surface of the piston have a molded scraper lip. These groove seals are for example, as a secondary seal in a master cylinder used, which is part of a hydraulic range.
Die Aufgabe der Erfindung besteht darin, eine hydraulische Kolben-Zylinder-Anordnung einzusetzen, die zu den Laufflächen des Kolbens hin abdichtet und außerdem einen Schmutzeintrag in diese verhindert.The The object of the invention is a hydraulic piston-cylinder arrangement insert, which seals to the running surfaces of the piston and also prevents a dirt entry into this.
Diese Aufgabe wird mit einer Dichtung mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.These Task is with a seal with the features of the claim 1 solved. Advantageous embodiments of the invention result from the dependent claims.
Nachfolgend wird die Erfindung anhand eines Ausführungsbeispiels und zugehöriger Zeichnungen näher erläutert.following The invention is based on an embodiment and associated drawings explained in more detail.
