    Rohrbruchvenm   mit durch das Treibmittel belastetem   Selbat8chlusskörper.   



   In der östorr. Patentschrift Nr. 21853 ist ein Rohrbruchventil beschrieben,. dessen   Sotbstschtusskörper, Hm   sein Gewicht und seinen Hub zu verringern und trotzdem eine sichere Wirkung zu erzielen, auf einem hohlen Zapfen verschiebbar und durch das Druckmittol belastet ist. 



   Gegenstand der vorliegenden Erfindung ist eine Einrichtung, welche bezweckt, diese Belastung des Selbstschlusskörpers durch das Druckmittel während der   Schliessbewegung   fortschreitend zu erhöhen und dadurch die   Abschlussgeschwindigkeit   zu verlangsamen. Diese Einrichtung besteht darin, dass an dem Selbstschlusskörper ein Dorn befestigt ist, welcher in die Bohrung des hohlen Zapfens hineinragt und während der Schliessbewegung den Ausströmquerschnitt fortschreitend vergrössert, im Gegensatz zu der Anordnung nach dem Stamm-Patente, bei welcher eine rasche Eröffnung dieses Querschnittes stattfindet. 



   Die Zeichnung zeigt beispielsweise den Selbstschlusskörper a mit einem in die Behrung g des Zapfens f hineinragenden Dorn e. Dieser vergrössert bei der Schliessbewegung

    Broken pipe with self-closing body loaded by the propellant.



   In the ostorr. Patent No. 21853 describes a pipe rupture valve. whose Sotbstschtusskörper, Hm to reduce its weight and its stroke and still achieve a safe effect, is displaceable on a hollow pin and loaded by the pressure medium.



   The subject of the present invention is a device which aims to progressively increase this load on the self-closing body by the pressure medium during the closing movement and thereby to slow down the closing speed. This device consists in that a mandrel is attached to the self-closing body, which protrudes into the bore of the hollow pin and progressively increases the outflow cross-section during the closing movement, in contrast to the arrangement according to the Stamm patent, in which this cross-section is opened quickly .



   The drawing shows, for example, the self-closing body a with a mandrel e projecting into the bore g of the pin f. This increases with the closing movement
