Description

fuHt/P F ichtulzg der Lagerbüchze von Drehkolben, insbesondere fürOvalradzähler Bei maschinen und Zählern mit Kolben, die um eine feststehende Achse drehen, muß in bestimmten Fällen der Austritt der fest- stehenden Achse gegenüber dem rotierenden Kolben besonders abge- dichtetwerden. Als l'littel hierzu wird vielfach Kunststoffy bei- Illf olge 1. IließenS der T- -L-el'avfoiao etron verwendet. Infolge Fließens der Kmiststoff- 7 scheibe nach längerer Betriebsdauer tritt unter Einwirkung gewis- ser Faktoren, wie \7ärme, hoher Druck usw., doch Undichtheit auf. Um diesen Mangel zu beseitigen, wird neuerungsemläß als Dicht- korper eine federnde Letallscheibe tellerfUruiger Gestalt ver- wendet. Durch Anziehen einer Mutter wird diese Scheibe axial verspannt, wobei sie radial auseinander gedrückt wird und dadurch bei entsprechend glatter Oberfläche der zur Berührung kommenden Teile sowohl innen als auch außen abdichtet. Da die Verformung der Scheibe im elastischen Bereich liegt, läßt sich die Abdichtscheibe jederzeit nach Entspannen leicht entfernen. fuHt / P F ichtulzg the bearing bushes of rotary pistons, in particular for oval gear meters For machines and counters with pistons that are around a fixed Rotate the axis, in certain cases the exit of the fixed the vertical axis in relation to the rotating piston. be sealed. As a means of doing this, plastic is often used. Illf olge 1. Let the T- -L-el'avfoiao etron used. As a result of the flow of fuel 7th after a long period of operation, the disk is certain to These factors, such as heat, high pressure, etc., but leakage. In order to eliminate this deficiency, a new sealing body a resilient lethal disc in the shape of a plate turns. By tightening a nut, this washer is braced axially, pressing it apart radially and thereby with a correspondingly smooth surface of the one that comes into contact Seals parts both inside and outside. Since the deformation of the disc is in the elastic range, the sealing disc can be easily removed at any time after releasing it.

Auf der Zeichnung ist ein Ausführungsbeispiel der Neuerung dargestellt. Darin ist in eine im nicht gezeichneten Drehkolben eingesetzte Büchse 1 ein Einsatzkörper 2 eingefügt. Der Einsatzkörper 2 endet etwas oberhalb der feststehenden Achse 3. Er ist weiterhin abgesetzt, so daß ein Zapfen 4 entsteht, der an seinem freien Ende als Gewindeansatz 5 ausgebildet ist. Ein auf den Zap- fen 4 aufgesteckte und gegen Verdrehen durch einen Zylinderstift ? li gesichertes Druckstück 6 bildet mit dem in&atzkSrper 2 einen Ringraum. In diesen ist die Dichtung eingelegt. Sie ist als tellerföruige Scheibe 8 ausgebildet. Wird nun durch eine Nutter 9 das Druckstück 6 axial gegen den Einsatzkörper 2 gepreßt, wodurch die federnde Dichtscheibe 8 etwas verformt wird, dann weitet diese sich radial nach außen aus und legt sich mit ihrem zylindrischen äußeren und inneren Mantel an die Innenwandung der Büchse 1 bzw. an die Außenfläche des Bolzens 4 an. Damit ist eine einwandfreie Dichtung erreicht.An exemplary embodiment of the innovation is shown in the drawing. An insert body 2 is inserted therein into a sleeve 1 inserted in the rotary piston (not shown). The insert body 2 ends a little above the fixed axis 3. It is further offset so that a pin 4 is formed which is designed as a threaded projection 5 at its free end. One on the tap fen 4 attached and secured against twisting by means of a cylinder pin? left The secured pressure piece 6 forms one with the in & atzkSrper 2 Annulus. The seal is inserted into these. It is designed as a plate-shaped disc 8. If the pressure piece 6 is now pressed axially against the insert body 2 by a nut 9, whereby the resilient sealing washer 8 is somewhat deformed, then it expands radially outward and lies with its cylindrical outer and inner jacket on the inner wall of the sleeve 1 or . to the outer surface of the bolt 4. A perfect seal is thus achieved.
