Description

  

  Selbsttätig anspringender Überfallheber.         U    m ein möglichst schnelles     Anspringet     der selbsttätigen Überfallheber zu erreichen,  muss der die Luftverdünnung im Heber  sehlauch bewirkende Wasserstrahl schon bei  einer geringen Überstauung der Überlauf  krone möglichst stark sein. Das wurde bis  her erreicht, indem man das Wasser auf dem  ganzen Umfang des Saugrohres in dieses  eintreten liess, wobei aber die das Saugrohr  überdeckende Haube breiter     als    dieses ge  macht wurde, was besonders bei mehreren  nebeneinander angeordneten Hebern kost  spielige Bauarbeiten erforderte.  



  Die vorliegende Erfindung bezweckt, ohne  solche Verbreiterung der das Saugrohr über  deckenden Haube den luftverdünnenden Was  serstrahl stark zu machen. Sie besteht darin,  dass die Länge der     Überlaufkante    grösser ge  macht ist, als die grösste Breite des Heber  saugrohres     beträgt,    zum Beispiel dadurch,  dass die     Überlaufkante    nach einer gebroche  nen Linie verläuft.  



  Eine beispielsweise Ausführungsform des  Erfindungsgegenstandes ist in beiliegender  Zeichnung dargestellt.         Fig.    1 zeigt im Vertikalschnitt nach der  Linie     b-b    von     Fig.    2 einen Überfallheber;       Fig.    2 den -dazu gehörigen Horizontal  schnitt nach der Linie     a=u    von     Fig.    1;       Fig.        ä    zeigt beispielsweise vier Überfall  kanten von gegenüber     Fig.    1 und 2 variier  tem Verlauf.  



  Bei einer Überstauung der     Überlaufkrone          (Fig.    1 und 2) um 5 cm wird der Wasser  strahl     S    etwa doppelt so stark werden, als  wenn die     Überlaufkante    senkrecht und ge  radlinig verliefe, da die Linie etwa doppelt  so lang ist wie die Breite B des Überfalles.  Natürlich lässt sich die Länge der Überlauf  krone noch verändern -und verlängern und  damit der Strahl     S    noch weiter verstärken,       wie    in     Fig.    3 im Grundriss dargestellt ist.



  Automatically starting hold-up lifter. In order for the automatic overflow siphon to start as quickly as possible, the water jet that causes the air to dilute in the siphon hose must be as strong as possible even if the overflow crown is only slightly flooded. This has so far been achieved by letting the water enter the suction pipe over the entire circumference, but the hood covering the suction pipe was made wider than this, which required costly construction work, especially with several jacks arranged next to one another.



  The present invention aims to make the air-thinning water jet strong without such widening of the hood covering the suction pipe. It consists in the fact that the length of the overflow edge is made greater than the greatest width of the siphon suction pipe, for example by the fact that the overflow edge runs along a broken line.



  An example embodiment of the subject matter of the invention is shown in the accompanying drawing. Fig. 1 shows, in vertical section along line b-b of Fig. 2, an overflow lifter; FIG. 2 shows the associated horizontal section along the line a = u of FIG. 1; Fig. Ä shows, for example, four raid edges of compared to Fig. 1 and 2 varied system course.



  With an overflow of the overflow crown (Fig. 1 and 2) by 5 cm, the water jet S will be about twice as strong as if the overflow edge perpendicular and straight ge, since the line is about twice as long as the width B of the raid . Of course, the length of the overflow crown can still be changed - and lengthened - and thus the beam S can be further strengthened, as is shown in plan in FIG. 3.
