Abstract
Die Erfindung betrifft einen Kolbenspeicher, mit einem axial beweglichen Kolben (8) in einer Gehäusebohrung (5), mit einer zwischen dem Kolben (8) und der Gehäusebohrung (5) angeordneten Dichtung (4), die innerhalb der Gehäusebohrung (5) fixiert ist, und mit einem Deckel (6) zum Verschluss der Gehäusebohrung (5). Die Gehäusebohrung (5) ist zur einfachen Aufnahme der Dichtung (4) als eine in Richtung des Deckels (6) im Durchmesser erweiterte Stufenbohrung ausgebildet.The invention relates to a piston accumulator, with an axially movable piston (8) in a housing bore (5), with a between the piston (8) and the housing bore (5) arranged seal (4) which is fixed within the housing bore (5) , And with a cover (6) for closing the housing bore (5). The housing bore (5) is designed to easily receive the seal (4) as a stepped bore in the direction of the cover (6) in diameter.
Description
Die Erfindung betrifft einen Kolbenspeicher, insbesondere einen Niederdruckspeicher für schlupfgeregelte hydraulische Kraftfahrzeug-Bremsanlagen, nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a piston accumulator, in particular a low-pressure accumulator for slip-controlled Hydraulic motor vehicle brake systems, according to the preamble of Patent claim 1.
In
der
Daher ist es die Aufgabe der vorliegenden Erfindung, einen einfachen, funktionssicheren Kolbenspeicher zu schaffen, der vorgenannte Nachteile nicht aufweist.Therefore It is the object of the present invention to provide a simple, To provide reliable piston accumulator, the aforementioned disadvantages do not having.
Diese Aufgabe wird erfindungsgemäß für einen Kolbenspeicher der angegebenen Art durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.These Task is according to the invention for a Piston accumulator of the specified type by the characterizing features of claim 1.
Bei der vorliegenden Erfindung handelt es sich um einen neuartigen Kolbenspeicher, bei dem die Gehäusebohrung als Sackbohrung ausgeführt ist, deren vom Bohrungsboden abgewandtes offene Ende sich nach außen als erweiterte Stufenbohrung fortsetzt, um eine möglichst einfache und dennoch sichere Aufnahme der Dichtung in die Gehäusebohrung zu gewährleisten. Das Anordnen der Dichtung in der Stufenbohrung kann hierbei vorteilhaft nach zwei Montagevarianten erfolgen, und zwar entweder vor dem Einsetzen des Kolbens in die Gehäusebohrung oder bevorzugt nach dem Einsetzen des Kolbens in die Gehäusebohrung, wozu das Ende des Kolbenhemds eine Anfasung aufweist.at the present invention is a novel piston accumulator, in which the housing bore is designed as a blind hole, whose facing away from the bore bottom open end to the outside than advanced stepped drilling continues to make it as simple as possible and yet to ensure secure acceptance of the seal in the housing bore. Arranging the seal in the stepped bore can be advantageous in this case after two installation variants, either before insertion of the piston in the housing bore or preferably after inserting the piston into the housing bore, for which the end of the piston skirt has a chamfer.
Durch die Stufenbohrung wird eine Beschädigung der Dichtung verhindert bzw. eine vorgeschädigte Dichtung sofort erkannt. Ein weiterer Vorteil ergibt sich durch die weit außenliegende Anordnung der Dichtung in der Stufenbohrung, wodurch der Kolben während seines Arbeitshubs nahezu über die gesamte Länge seines Kolbenhemds mit der Speicherflüssigkeit in der Gehäusebohrung benetzt und damit auch geschmiert werden kann. Ein Trockenlauf und eine unzulässige Kolbenreibung wird somit auf verblüffend einfache Weise erfolgreich vermieden. Durch die großflächige Benetzung der Gehäusebohrung bis zur Dichtung wird ferner der Luftsauerstoff der Atmosphäre von der Gehäusebohrung ferngehalten, so dass eine Oxidation bzw. Korrosion der Gehäusewand ausgeschlossen werden kann.By The stepped bore prevents damage to the seal or a previously damaged one Seal recognized immediately. Another advantage comes from the far outboard Arrangement of the seal in the stepped bore, causing the piston while his workhub almost over the entire length his piston shirt with the storage liquid in the housing bore wetted and thus can be lubricated. A dry run and a unacceptable Piston friction thus succeeds in a surprisingly simple manner avoided. Due to the extensive wetting the housing bore up to the seal is also the atmospheric oxygen of the atmosphere of the housing bore kept away, so that oxidation or corrosion of the housing wall can be excluded.
Weitere Merkmale, Vorteile und Anwendungsmöglichkeiten der Erfindung gehen aus den Unteransprüchen hervor und werden anhand der Beschreibung zweier Ausführungsbeispiele näher erläutert.Further Features, advantages and applications of the invention go from the dependent claims and will become apparent from the description of two embodiments explained in more detail.
