KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Die wesentliche Bedingung eines guten Kohlensäureventils ist anhaltendes Dichthalten. Diese Bedingung wird bei den bisher üblichen Ausführungen der Abdichtung nur kurze Zeit erfüllt.The essential condition of a good carbon dioxide valve is to keep it tight for a long time. This condition only applies for a short time in the previously customary designs of the seal Fulfills. Das Hartgummistückchen η verändert gerade an der Abdichtungsfläche seine Form, quetscht sich zuerst in die Ausströmungsöffnung α hinein, wird uneben und dadurch undicht. Dieses Hineinquetschen des Hartgummis in die Ausströmungsöffnung wird bei der vorliegenden Erfindung verhindert durch den Stift k, welcher in seinem stärksten Theil die Ausströmungsöffnung gerade ausfüllt. Aufserdem ist dieser Stift konisch gedreht und läfst dadurch äufserst feine Querschnittveränderungen zu, was für den Betrieb von gröfstem Vortheil ist.The hard rubber piece η is just changing its shape on the sealing surface, first squeezes into the outflow opening α , becomes uneven and therefore leaks. This squeezing of the hard rubber into the outflow opening is prevented in the present invention by the pin k, which in its strongest part just fills the outflow opening. In addition, this pin is turned conically and allows extremely fine changes in cross-section, which is of great advantage for operation. Patent-Anspruch:Patent claim: Ein Hartgummiventil für Kohlensäurebehälter, gekennzeichnet durch einen Stift k, welcher derartig im Hartgummikörper η befestigt ist, dafs er bei geschlossenem Ventil die Ausströmungsöffnung ganz ausfüllt, um ein Einpressen des Hartgummis in die Oeffnung zu vermeiden.A hard rubber valve for carbon dioxide containers, characterized by a pin k, which is fastened in the hard rubber body η in such a way that when the valve is closed it completely fills the outflow opening in order to avoid pressing the hard rubber into the opening.
