KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. PATENTSCHRIFTPATENT LETTERING KLASSE 47: Maschinenelemente.CLASS 47: Machine elements. Patentirt im Deutschen Reiche vom i. April 1885 ab.Patented in the German Empire from i. April 1885. Bei dem dargestellten Ventilhahn ist die Schraube b, mittelst deren der Ventilkörper a heruntergedrückt wird, vollständig aufser Berührung mit der den Hahn durchströmenden Flüssigkeit ohne jede Stopfbüchse u. dergl. in den Deckel c eingesetzt. Der eiförmige, hohle Ventilkörper α aus elastischem Stoff schliefst den Raum d, worin die Schraube b, welche auch durch eine einfache Druckstange ersetzt werden kann, bewegt wird, sofort vollständig ab, sobald er sich nur ganz wenig von seinem Sitz e abhebt, um Flüssigkeit durchlaufen zu lassen. Wenn man die Belastung bei b aufhebt, wird das Ventil durch den Druck der bei f einströmenden Flüssigkeit von seinem Sitz e abgehoben und tritt in den sich nach oben verjüngenden Raum d, welchen er gegen die Flüssigkeit vollkommen abschliefst, indem sich seine elastischen Seitenwände fest an die Wandungen des Raumes d anlegen, Fig. 3. Dadurch wird die Anbringung einer Dichtungsvorrichtung für die Ventilstange b überflüssig.In the valve tap shown, the screw b, by means of which the valve body a is pressed down, is completely inserted into the cover c without any stuffing box or the like, without touching the liquid flowing through the tap. The egg-shaped, hollow valve body α made of elastic material closes the space d, in which the screw b, which can also be replaced by a simple push rod, is moved, immediately and completely, as soon as it lifts just a little from its seat e , for liquid to run through. When the load at b is removed, the valve is lifted from its seat e by the pressure of the liquid flowing in at f and enters the upwardly tapering space d, which it closes off completely against the liquid because its elastic side walls are firmly attached create the walls of the space d , Fig. 3. This makes the attachment of a sealing device for the valve rod b superfluous. Patenτ-Ansprüch:Patent claims: Ein Hahn mit eiförmigem Ventilkörper a, welcher bei geöffnetem Durchlafs durch den Druck der einströmenden Flüssigkeit in den sich kegelförmig verjüngenden Raum d gedrückt wird und denselben dadurch vollständig abschliefst, zum Zwecke der Ersparung von Dichtungsmitteln für die Ventilstange.A cock with an egg-shaped valve body a, which, when the passage is open, is pressed by the pressure of the inflowing liquid into the conically tapering space d and thereby completely closes it off, in order to save sealing means for the valve rod.
