KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand vorliegender Erfindung ist ein zum Einlassen von Aufsenluft und selbstthätigem Entlasten des inneren Ueberdruckes mit einem sich dadurch kennzeichnenden Doppelventil ausgestatteter Fafsspund, in welchem dasselbe seinen Sitz hat und mittelst einer einzigen Druckfeder normal verschlossen gehalten wird.The subject of the present invention is an external air intake and an automatic one Relief of the internal overpressure with a double valve characterized by it equipped barrel in which it has its seat and by means of a single one The compression spring is kept normally closed.
Auf beiliegender Zeichnung ist dieser Ventil-. spund für die drei verschiedenen Ventilstellungen im Querschnitt veranschaulicht, und zwar zeigt:This valve is shown in the accompanying drawing. bung for the three different valve positions illustrated in cross section, namely shows:
Fig. ι die beiden Ventile in geschlossener Stellung,Fig. Ι the two valves in the closed position,
Fig. 2 das Einlafsventil undFig. 2 the inlet valve and
Fig. 3 das Entlastungsventil in offener Stellung. 3 shows the relief valve in the open position.
In die an der unteren Grundseite vorgesehene Centralhülse B ist der mit der Oeffnung F versehene Hohlsitz derart eingeschraubt, dafs sein oberer Rand den Ventilsitz bildet, auf welchen das ringförmige Entlastungsventil O gelegt ist. Gegen die untere Fläche des letzteren legt sich das den Durchlafs abschliefsende Einlafsventil O1, welches in der Mitte die oben aus dem Spundkörper hervortretende Stange T trägt. An letzterer ist die Scheibe D befestigt, welche sich mit vier vorstehenden Rippen bezw. Knöpfen JV gegen den Boden der Hülse B legend, durch letztere den Weg für die Entweichungsgase freihält. Die beiden Ventile O und O1 werden dadurch fest verschlossen gehalten, dafs die zusammengeprefste Schraubenfeder R sich oben gegen die Scheibe D und unten auf das Ringventil O stützt (Fg. 1). The hollow seat provided with the opening F is screwed into the central sleeve B provided on the lower base side in such a way that its upper edge forms the valve seat on which the annular relief valve O is placed. The inlet valve O 1 , which closes the passage and carries the rod T protruding from the top of the bung body, lies against the lower surface of the latter. On the latter, the disk D is attached, which BEZW with four protruding ribs. Place the button JV against the bottom of the sleeve B , the latter keeping the way free for the escape gases. The two valves O and O 1 are kept tightly closed by the fact that the compressed helical spring R is supported at the top against the disk D and at the bottom against the ring valve O (FIG. 1).
Der Vorgang ist folgender: ,The process is as follows:
Soll Aufsenluft eingelassen werden, so wird entweder durch äufseren Ueberdruck das Ventil O1 selbstthätig oder mittelst des auf Stange T wirkenden Daumens niedergedrückt (Fig. 2), wobei auch innerer Ueberdruck entlastet werden kann; wird jedoch der letztere stärker als der Federdruck, so hebt derselbe die .beiden Ventile an (Fig. 3), so dafs nun die Entlastung selbstthätig stattfindet.If outside air is to be admitted, the valve O 1 is depressed either automatically by external overpressure or by means of the thumb acting on rod T (FIG. 2), whereby internal overpressure can also be relieved; but if the latter becomes stronger than the spring pressure, it lifts the two valves (Fig. 3), so that the pressure then takes place automatically.
