摘要： Die Erfindung betrifft ein Unterdruck-Läuteraggregat, bei dem mittels einer über eine Saugleitung angeschlossenen Vakuumpumpe ein Unterdruck über der zu läuternden Glasschmelze erzeugt wird und bei dem an der Saugleitung ein Ventil zum Zuführen von Falschluft aus der Atmosphäre abzweigt, um die Druckverhältnisse im Unterdruckaggregat konstant zu halten. Die Läuterung wird dadurch verbessert, dass der Unterdruckkreis mit einem regelbaren Leck versehen wird, das einen Zufluss von Falschluft in Abhängigkeit von verschiedenen Messgrößen regelt und so konstante Läuterungsverhältnisse schafft.

摘要： The invention relates to a method and a device for refining a glass melt, using negative-pressure apparatus. According to the invention, the glass melt is fed to a refining bench by means of an uptake pipe and is discharged from the refining bench by means of a downpipe, a negative pressure being created over the flow of glass in the refining bench. The invention is characterised in that the uptake pipe and/or the downpipe and/or the refining bench has/have at least one component consisting of at least one refractory metal and/or of a refractory metal alloy as the glass contact material.
