KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die vorliegende Erfindung bezweckt, bei Kreiselpumpen oder Gebläsen, überall, wo Spalten zwischen laufenden und ruhenden Teilen auftreten und auf den beiden Seiten der Spalten verschiedene Drucke herrschen, die durch die Spalten durchtretende Gasbezw. Flüssigkeitsmenge möglichst gering zu halten. Bisher hat man den laufenden Teil mit möglichst wenig Spiel in dem festen ίο laufen lassen. Dieses Spiel konnte aber nicht beliebig klein genommen werden, da auf ungenaues Laufen des sich drehenden Teiles Rücksicht zu nehmen war, ein Schleifen an dem unnachgiebigen, festen Teil aber vermieden werden mußte.The present invention is intended for centrifugal pumps or fans wherever Gaps occur between moving and resting parts and on both sides different pressures prevail in the columns, the gas or gas passing through the columns. To keep the amount of liquid as low as possible. So far you have the current part with as little play as possible in the fixed ίο let it run. However, this game could not be taken arbitrarily small because it was imprecise Allowance had to be made for the rotating part to run, but grinding on the unyielding, fixed part was avoided had to become.
Das Wesen der vorliegenden Erfindung besteht demgegenüber in folgendem:In contrast, the essence of the present invention consists in the following:
Der Ring α ist mit möglichst geringem Spiel auf den Teil b aufgepaßt und liegt mit seiner einen ebenen Fläche gegen den Teil c an; dieser Teil c hat reichlich Spiel gegen b. In dem Raum d herrscht Überdruck dem Raum e gegenüber, so daß der Ring a an den Teil c angepreßt wird. Es ist nun gleichgültig, ob sich b bewegt und c ruht oder umgekehrt. Als Gas- bezw. Flüssigkeit durchlassende öffnung kommt nur der äußerst geringe zylindrische Spalt zwischen α und b in Betracht.The ring α is fitted with the least possible play on the part b and rests with its one flat surface against the part c ; this part c has plenty of play against b. In the space d there is overpressure in relation to the space e , so that the ring a is pressed against the part c. It does not matter whether b moves and c rests or vice versa. As gas or Only the extremely small cylindrical gap between α and b comes into consideration.
