KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Vorliegende Erfindung betrifft ein Ventil, bei dem die Durchgangsöffnungen in einem, zylindrischen Körper angeordnet sind, den ein aus einem aufgeschnittenen federnden Ringe bestehender Abschlußkörper umgibt.The present invention relates to a valve in which the through openings in a, cylindrical body are arranged, one of a cut open resilient Rings of existing closure body surrounds. Das Neue am vorliegenden Ventil besteht nun darin, daß an den zur Hubbegrenzung des Ringes dienenden Stegen oder in sonst geeigneter Weise Federn angeordnet sind,The new thing about the present valve is that it is used to limit the stroke of the ring serving bars or springs are arranged in some other suitable manner, ίο die sich von außen gegen den Ring legen und auf diese Weise dessen Federkraft verstärken und einen dichten Anschluß an den Ventilkörper bewirken.ίο which lie against the ring from the outside and in this way increase the spring force and create a tight connection to the Effect valve body. Die Einrichtung ist namentlich für Ventile von großem Durchmesser geeignet.The device is particularly suitable for valves with a large diameter. Federnde Ventilringe mit Zusatzfedern sind bereits vorgeschlagen worden, doch wirkten bei den bekannten Anordnungen die Federn nur auf die Ringenden, während sie bei der vorliegenden Anordnung auf den Umfang des Ringes gleichmäßig einwirken. Der Ring erhält dabei überall gleichmäßige Widerstandsfähigkeit und kann sich gleichmäßig vom Sitz abheben.Resilient valve rings with additional springs have already been proposed, but worked in the known arrangements, the springs only on the ring ends, while in the act evenly on the circumference of the ring in the present arrangement. The ring receives uniform resistance everywhere and can move evenly from the Lift off the seat. Auf der Zeichnung ist ein Ventil gemäß vorliegender Erfindung in mehreren Ausführungsbeispielen in den Fig. 1 bis 6 dargestellt. On the drawing is a valve according to the present invention in several embodiments shown in Figs. Der aufgeschnittene, federnde, sehr dünne Abschlußring α liegt auf erhöhten ringförmigen Sitzleisten b des zylindrischen Körpers c, in dem sich die Durchgangsöffnungen d befinden. Der federnde Ring α ruht infolge der Aussparung f zwischen den Leisten b nur auf diesen schmalen Leisten auf und ist demgemäß fast vollständig entlastet. The cut, resilient, very thin end ring α is on raised annular seat rails b of the cylindrical body c, the passage openings are in the d. The resilient ring α rests due to the recess f between the strips b only on these narrow strips and is therefore almost completely relieved. Die Verdrehung des Ringes α auf seinem Sitz wird durch eine an dem Körper c vorgesehene, zwischen die Ringenden eingreifende Leiste g verhindert. Zur weiteren Führung des Verschlußringes und zur Hubbegrenzung dienen die außerhalb des Ringes angeordneten Stege h. The rotation of the ring α on its seat is prevented by a bar g provided on the body c and engaging between the ring ends. The webs h arranged outside the ring serve to further guide the locking ring and to limit the stroke. Zur Verstärkung der Federkraft des Ab-Schlußringes α ohne Vergrößerung der Maße des Ringes und zwecks dichten Anschlusses an den Ventilkörper sind Zusatzfedern i an den Stegen h angeordnet. Zweckmäßig werden hierzu, wie dargestellt, dünne Blattfedern benutzt, die an zwei Stellen den Ring berühren und quer zum Steg befestigt sind. Gegebenenfalls können aber auch, wie Fig. 6 zeigt, zwischen dem Steg und dem Ring a angeordnete Federn i benutzt werden, wobei die Federn auf die Ränder des Ringes einwirken und ein Abklappen der Ringränder bei schwachen Ringen verhindert wird.To increase the spring force of the closing ring α without increasing the size of the ring and for the purpose of a tight connection to the valve body, additional springs i are arranged on the webs h . For this purpose, as shown, thin leaf springs are expediently used, which touch the ring at two points and are fastened transversely to the web. If necessary, however, as FIG. 6 shows, springs i arranged between the web and the ring a can be used, the springs acting on the edges of the ring and preventing the ring edges from folding down in the case of weak rings.
