Description

Poröser Belüftungskörper In dem Patent 543 776 sind Belüftungskörper angegeben, bei denen die Luft durch durchstochene Gummihülsen in den aus einer porösen Masse bestehenden Belüftungskörper tritt. Statt der durchstochenen Gummihülsen, welche sich nur bei einem bestimmten, Luftdruck öffnen, kann man ein Metallrohr verwenden, das einzelne Löcher aufweist, welche mit einem Gummiring überdeckt sind. Bei einem bestimmten Luftdruck dehnt sich der Gummiring aus, und die Luft kann aus dem Loch des Rohres durch den Zwischenraum zwischen dem Gummiring und dem Metallrohr in den Belüftungskörper eintreten. Für bestimmte Gase ist die Anwendung von Gummi nicht zulässig, in diesem Fall tritt die Luft in den Belüftungskörper nach Fig. i aus dem inneren Metallrohr a durch den äußeren Belüftungskörper b in die Flüssigkeit. Das innere Metallrohr a ist durch ein einstellbares, federbelastetes Kugelventil c geschlossen, welches sich bei einem bestimmten Luft- oder Gasdruck hebt und das Gas durch die Öffnungen d in den: Belüftungskörper b eintreten läßt. Sinkt der Luftdruck, so schließt sich das Ventil c, und das Gas kann aus dem äußeren Körper b nicht in das innere Metallrohr a und dessen Verbindungsleitungen zurücktreten.Porous ventilation body In the patent 543 776 ventilation bodies are specified in which the air passes through pierced rubber sleeves into the ventilation body consisting of a porous mass. Instead of the pierced rubber sleeves, which only open at a certain air pressure, you can use a metal tube that has individual holes that are covered with a rubber ring. At a certain air pressure, the rubber ring expands and the air can enter the ventilation body from the hole in the tube through the space between the rubber ring and the metal tube. The use of rubber is not permitted for certain gases, in this case the air enters the ventilation body according to FIG. I from the inner metal tube a through the outer ventilation body b into the liquid. The inner metal tube a is closed by an adjustable, spring-loaded ball valve c, which rises at a certain air or gas pressure and allows the gas to enter through the openings d into the ventilation body b. If the air pressure drops, the valve c closes and the gas cannot escape from the outer body b into the inner metal tube a and its connecting lines.

Claims (1)

PATENTANSPRÜCFIE: i. Poröser Belüftungskörper gemäß Patent 543 776, bestehend aus einem inneren Luftzufuhrrohr, dessen einzelne Löcher durch einen Gummiring verschlossen werden, der sich bei einem bestimmten Luftüberdruck ausdehnt und die Luft zwischen seiner inneren Wand und der äußeren Wand des Metallrohres in den äußeren Belüftungskörper ein-, jedoch nicht in die Zuführungsleitung zurücktreten läßt. z. Belüftungskörper nach Patentanspruch i, dadurch gekennzeichnet, daß der Gummiring durch ein einstellbares, metallenes Rückschlagventil ersetzt wird.PATENT CLAIM: i. Porous ventilation body according to patent 543 776, consisting of an inner air supply tube, the individual holes of which are through a rubber ring are closed, which expands at a certain excess air pressure and the Air between its inner wall and the outer wall of the metal pipe in the outer Aeration body, but can not step back into the supply line. z. Ventilation body according to claim i, characterized in that the rubber ring is replaced by an adjustable, metal check valve.
