PATENTAMT.PATENT OFFICE.
Den Gegenstand der Erfindung bildet ein gasdurchlässiger Verschluß für galvanische Trockenelemente, Akkumulatoren u. dgl. Die transportfähigen galvanischen Elemente bestehen in der Regel aus einem Metallbehälter, in welchem die Kohlenelektrode mit der Füllmasse enthalten ist. Oben wird der Raum zwischen der Kohlen- und Zinkclektrode gewöhnlich durch eine leicht erstarrende MasseThe subject of the invention is a gas-permeable closure for galvanic Dry elements, accumulators, etc. The transportable galvanic elements exist usually from a metal container, in which the carbon electrode with the filling compound is included. At the top the space between the carbon and zinc electrodes becomes common by a slightly solidifying mass
ίο ausgegossen. Bei Gasbildung wird aber diese Vergußmasse durch den inneren Druck in die Höhe getrieben. Es lösen sich einzelne Teile dieser Masse, wodurch die Isolation zerstört wird und Kurzschlüsse eintreten.ίο poured out. When gas is formed, however, this Casting compound driven up by the internal pressure. Individual parts come loose this mass, which destroys the insulation and short circuits occur.
Durch den Gegenstand der Erfindung sollen diese Mängel in einfacher Weise beseitigt werden. Das Wesen der Erfindung besteht darin, daß an Stelle der Vergußmasse ein Abschlußring mit einer entsprechend durchbrochenen elastischen Membrane vorgesehen ist, die ventilartig wirkt und dadurch den Gasaustritt regelt. Bei Bildung von Gasen wird die als Ventil wirkende Membrane nämlich in die Höhe getrieben und das Entweichen der Gase gestatten, sonst aber infolge der natürlichen Elastizität einen dichten Abschluß geben.The object of the invention is intended to remedy these deficiencies in a simple manner. The essence of the invention is that instead of the potting compound, an end ring is provided with a correspondingly perforated elastic membrane, the valve-like acts and thereby regulates the gas outlet. When gases are formed, the as Valve-acting membrane namely driven up and the escape of the gases allow, but otherwise give a tight seal due to the natural elasticity.
Auf der Zeichnung ist eine Ausführungsform der Erfindung zur Darstellung gebracht.
Es bezeichnet α eine Metallhülse, in welche ein Zinkeinsatz δ eingefügt ist. c ist die
Kohlenelektrode mit nach außen ragendem Polansatz d. Als Abschluß dient eine Blechscheibe
e mit elastischem Mittelteil, z. B. einer Gummiplatte f. Letztere ist in der
Mitte mit einer Durchbrechung versehen, so daß der Stift d hindurchtreten kann. Der
Stift d wirkt als Ventilsitz für die Membrane f. Der Ring e ist mit der Hülse α durch Verlötung
i verbunden.An embodiment of the invention is shown in the drawing.
It designates α a metal sleeve into which an insert is inserted zinc δ. c is the carbon electrode with outwardly protruding pole attachment d. A sheet metal disc e serves as a seal with an elastic middle portion such. B. a rubber plate f. The latter is provided in the middle with an opening so that the pin d can pass through. The pin d acts as a valve seat for the membrane f. The ring e is connected to the sleeve α by soldering i .
Bilden sich Gase, so heben sie die als Ventil wirkende Gummischeibe f von dem Kohlenstift d ab. Die Gase können in Pfeilrichtung g entweichen. Beim Aufhören des inneren Gasdruckes schließt das Ventil f infolge seiner natürlichen Elastizität wieder dicht an.If gases are formed, they lift the rubber washer f, which acts as a valve, from the carbon pin d . The gases can escape in the direction of arrow g. When the internal gas pressure ceases, the valve f closes again tightly due to its natural elasticity.
