Kolbenventil.

die Scheiben durch den Schliessdruck ein wenig deformiert, u. zw. flacher gedrückt (Fig. 4). so dass sieh die Randflächen i der Scheiben b an die Innenfläche der Büchse g anlegen und mit ihr abdichten. Hiebei erweitert sich zwar der Schlitz d jeder Scheibe b ein wenig. wajedoch keine Undichtigkeit zur Folge hat, da der Schlitz d jeder Scheibe, wie bereits erwähnt wurde. durch die benachbarten Scheiben abgedeckt wird.

deformiert, und in diesem Zustand wird das Bündel von Einzelscheihen nach einer Zylinderfläche abgeschliffen (Fig. 4), deren Durchmesser genau dem Innendurchmesser der Dichtung- büchse y entspricht.
Nach dem Schleifen kehren die Scheiben b wieder in den Spannung-

scheilJen 11 vollkommen die Form der Innenwand der Büchse g an und gelangen so zur Anlage an die zylindrische Innenfläche der Büchse g. Beim Öffnen des Ventiles kehren die Scheiben b wieder in den spannungslosen Zustand (Fig. 2) zurück, so dass der Schliesskörper. ohne an der Innenwand der Büchse g zu reiben, angehoben werden kann.
Die Innenfläche der Buche 9 kann auch die Form eines sich nach unten schwach verjüngenden Kegels erhalten. Das den Schliesskörper bildende Bündel der Einzelscheiben b @ wird dann im gespannten Zustand nach einer genau gleichen Kegelfläche abgeschliffen. Die Randflächen i der Einzelscheiben b wirken dann in einem gewissen Mass nach Art der kegelförmigen Sitzflächen der üblichen Sehliesskörper, nur mit dem Unterschied, dass die Sitzflächen i nachgiebig sind und daher nicht nachgeschliffen werden müssen.
Das beschriebene Ventil gewährt die Vorteile, dass es durch die Vermeidung aller nichtmetallischen Teile den höchsten Drücken und Temperaturen dauernd standhält und dass für eine wirksame Abdichtung ein geringer Schliessdruck ausreicht.
PATENT-ANSPRÜCHE :
1. Kolbenventil, dadurch gekennzeichnet, dass der Ventilschliesskörper aus einem Bündel

des Ventilgehäuses (f) bzw. einer darin angeordneten Einsatzbüchse (g) abdlichten.

the discs are slightly deformed by the closing pressure, u. between pressed flat (Fig. 4). so that you see the edge surfaces i of the discs b apply to the inner surface of the sleeve g and seal with it. In doing so, the slot d of each disk b widens a little. wajedoch does not result in any leakage, since the slot d of each disc, as already mentioned. is covered by the adjacent panes.

deformed, and in this state the bundle of individual rows is ground to a cylindrical surface (Fig. 4), the diameter of which corresponds exactly to the inner diameter of the sealing sleeve y.
After grinding, the disks b return to tension
EMI2.2
scheilJen 11 perfectly match the shape of the inner wall of the sleeve g and thus come to rest against the cylindrical inner surface of the sleeve g. When the valve is opened, the disks b return to the de-energized state (FIG. 2), so that the closing body. can be lifted without rubbing the inner wall of the sleeve g.
The inner surface of the beech 9 can also have the shape of a cone that tapers slightly downwards. The bundle of individual disks b @ that forms the closing body is then ground down in the tensioned state to form an exactly identical conical surface. The edge surfaces i of the individual disks b then act to a certain extent in the manner of the conical seat surfaces of the usual closing bodies, with the only difference that the seat surfaces i are flexible and therefore do not have to be reground.
The valve described provides the advantages that, by avoiding all non-metallic parts, it permanently withstands the highest pressures and temperatures and that a low closing pressure is sufficient for effective sealing.
PATENT CLAIMS:
1. Piston valve, characterized in that the valve closing body consists of a bundle
EMI2.3
of the valve housing (f) or an insert sleeve (g) arranged therein.
