Description

  

      queeksilber        dampf-Vakuumpumpe.       Bei den bekannten     Quecksilberdampf-Va-          kuumpumpen    der     Gaedeschen        Bauart    dient  als     Absahluss    der Pumpe, wie     Fig.    3 zeigt,  ein mittelst Flansch aufgeschraubter Deckel  11 .mit einem konzentrischen Rohransatz 12,  an welchen die Vakuumleitung 10 durch ei  nen Schliff oder einen zweiten Flansch an  geschlossen wird. Im Hinblick auf die Dich  tigkeit -der Vakuumeinrichtung sollte jede  Dichtungsstelle     vermieden    werden.

   Daher  wird erfindungsgemäss die Vakuumleitung  und die Pumpe so ausgebildet, dass eine je  ner Dichtungsstellen fortfällt, so dass also  nach Lösen der Verbindung zwischen Pumpe  und Vakuumleitung die Einbauten zur Füh  rung des Quecksilberdampfes     herausgenom-          inen    werden können.  



  Die     Abb.    1 und 2 zeigen zwei     Ausfüh-          ringsbeispiele,    bei denen die Einbauten 4 aus  dem     Gehäuse    5     durch    die Öffnung 6     heraus-          "rvzogen    werden können, wenn die Qlleck-         silberschliffdichtung    1, 2, 3,     bezw.    die       Flansehdichtung    7, 8, 9 gelöst ist.  



  Es ist natürlich nicht nötig, dass die Va  kuumleitung 10     .denselben    Durchmesser hat  wie das Rohr 5. Man kann sinngemäss auch  eine beliebige andere Dichtungsart benutzen.  Dabei ist wesentlich, dass das Ende der Va  kuumleitung selbst die     Anschlussstelle    an die  Pumpe bildet, wodurch eine zweite Zwischen  verbindung fortfällt.



      Queeksilver Steam Vacuum Pump. In the known mercury vapor vacuum pumps of the Gaede design, as shown in FIG. 3, a cover 11 screwed on by means of a flange serves as a seal for the pump is closed. With regard to the tightness of the vacuum device, any sealing point should be avoided.

   Therefore, according to the invention, the vacuum line and the pump are designed in such a way that one of the sealing points is omitted, so that after the connection between the pump and vacuum line has been loosened, the built-in components for guiding the mercury vapor can be removed.



  Figs. 1 and 2 show two exemplary embodiments in which the internals 4 can be pulled out of the housing 5 through the opening 6 when the polished silver joint seal 1, 2, 3 or the flange seal 7, 8 , 9 is solved.



  It is of course not necessary for the vacuum line 10 to have the same diameter as the pipe 5. Any other type of seal can also be used. It is essential that the end of the vacuum line itself forms the connection point to the pump, so that a second intermediate connection is omitted.

 

Claims (1)

PATENTANSPRUCH: Quecksilberdampf-Vakuumpumpe mit Ein bauten zur Verstärkung der Pumpwirkung des hochsteigenden Quecksilberdampfes, da durch gekennzeichnet, dass die Vorvakuum- leitung ohne weiteres Deckelstück über eine Dichtung unmittelbar au die obere Öffnung der Pumpe -angeschlossen ist. PATENT CLAIM: Mercury vapor vacuum pump with built-in components to increase the pumping effect of the rising mercury vapor, as this is characterized by the fact that the fore-vacuum line is directly connected to the upper opening of the pump via a seal without an additional cover piece.
