Gegenstand der Erfindung ist ein Hahn mit besonderer, im Küken verschiebbar gelagerter Dichtungsplatte, die durch Federn gegen die Gehäusewand gepreßt wird. Derartige Hähne sind bereits bekannt, weisen aber den Nachteil auf, daß die Dichtungsplatte beim Drehen des Kükens auf der Gehäusewand schleift und daher bei häufiger Betätigung des Hahnes einer starken Abnutzung unterworfen ist.The subject of the invention is a tap with a special, slidably mounted in the chick Sealing plate which is pressed against the housing wall by springs. Such taps are already known but the disadvantage that the sealing plate when turning the plug on the housing wall grinds and therefore with frequent use of the tap a strong wear is subject. Gemäß der Erfindung soll dieser Nachteil der bekannten Hähne mit im Küken gelagerter verschiebbarer Dichtungsplatte dadurch vermieden werden, daß die Dichtungsplattc mit Vorsprüngen in Gestalt von Kugeln versehen ist, die in der Schließstellung des Hahnkükens in entsprechenden Aussparungen des Gehäuses liegen, beim Öffnen jedoch auf die Gehäusewand auflaufen und dadurch die ?.o Dichtungsplatte von der Gehäusewand abdrücken. According to the invention, this disadvantage of the known taps with stored in the chick displaceable sealing plate can be avoided in that the Dichtungsplattc is provided with projections in the form of balls, which in the closed position of the cock plug lie in corresponding recesses of the housing, but when opening run onto the housing wall and thereby the ? .o Press the sealing plate off the housing wall. Die Einrichtung nach der Erfindung kann bei Hähnen normaler Bauart auch nachträglich eingebaut werden.The device according to the invention can also be retrofitted to taps of normal design to be built in. Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in den Abb. 1 bis 6 dargestellt. An exemplary embodiment of the subject matter of the invention is shown in FIGS. 1 to 6. Der Hahn weist einen in den Abb. 5 und 6 dargestellten Dichtungskörper auf, der in Bohrungen c und d des Hahnkükens lose eingesetzt ist, ohne daß dadurch der zur Führung dienende Teil der Oberfläche des Kükens wesentlich verkleinert und die normale D urchllußöffnung des Hahnes eingeschnürt oder erweitert wird. Die Bohrungen zur Aufnahme des Dichtungskörpers, die in gewöhnlichen Hähnen auch nachträglich angebracht werden können, stehen im rechten Winkel zur Richtung der Durchflußöffnung im Küken und berühren die Durchflußöffnung im Küken nicht. Sie nehmen den Dichtungskörper mit seinen Führungsbolzen e auf und sind so tief, daß der Dichtungskörper ganz in ihnen verschwindet, wenn seine höchsten Erhebungen, nämlich die Kugeln 0·, durch die Wandung des Gehäuses (Fig. 1 und 2) radial nach innen in das Küken gedrückt werden. Diesem Druck entgegen wirkt die Feder/ unter dem Dichtungskörper. Wenn das Hahnküken in die Schließstellung kommt, bewirkt diese Feder, daß der Dichtungskörper und damit sein Dichtungsplättchen/i fest gegen das Zulauflochö des Gehäuses (Fig. 1 und 2) gedrückt wird. Das wird dadurch ermöglicht, daß sich in der Gehäuseinnenwand (Fig. 1 und 2) zwei Vertiefungen α befinden, in welche die Kugeln g des Dichtungskörpers einschnappen, wenn das Hahnküken in die Schließstellung gedreht wird.The cock has a sealing body shown in Figs. 5 and 6, which is loosely inserted in bores c and d of the cock plug without the part of the plug surface serving for guidance being significantly reduced and the normal D urchllußöffung of the cock constricted or is expanded. The holes for receiving the sealing body, which can also be made subsequently in ordinary taps, are at right angles to the direction of the flow opening in the plug and do not touch the flow opening in the plug. They take up the sealing body with its guide pins e and are so deep that the sealing body disappears completely in them when its highest elevations, namely the balls 0, through the wall of the housing (Fig. 1 and 2) radially inward into the Chick being pressed. The spring / under the sealing body counteracts this pressure. When the cock plug comes into the closed position, this spring causes the sealing body and thus its sealing plate / i to be pressed firmly against the inlet hole of the housing (FIGS. 1 and 2). This is made possible by the fact that there are two recesses α in the inner wall of the housing (FIGS. 1 and 2), into which the balls g of the sealing body snap when the cock plug is turned into the closed position. 60 Pat εν τ Anspruch: 60 Pat εν τ claim: Hahn mit besonderer, im Küken verschiebbar gelagerter Dichtungsplatte, die durch Federn gegen die Gehäusewand gepreßt wird, dadurch gekennzeichnet, daß die Dichtungsplatte mit Vorsprüngen in Gestalt von Kugeln versehen ist, die in der Schließstellung des Hahnkükens in entsprechenden Aussparungen des Gehäuses liegen, beim Öffnen jedoch auf die Gehäusewand auflaufen und dadurch die Dichtungsplatte von der Gehäusewand abheben. Cock with a special sealing plate, which is slidably mounted in the plug is pressed against the housing wall by springs, characterized in that the sealing plate is provided with projections in the form of balls, which in the closed position of the cock plug in corresponding recesses of the housing are, when opening, however, on the Run up the housing wall and thereby lift the sealing plate from the housing wall.
