Gebläse.Fan.
Bei Gebläsen nach den Patenten 252919 und 257375 hat sich gezeigt, daß bei höheren Drucken, die an der Grenze der Flüssigkeitsspannung liegen, das Wasser teilweise aus den Zellen verdrängt wird, so daß sich hieraus eine Vergrößerung des schädlichen Raumes ergibt; ein Teil des gespannten Fördermittels wird auf diese Weise von der Druckseite auf die Saugseite hinübergebracht und verhindert hier das Ansaugen, bis er auf Saugspannung expandiert ist.With blowers according to patents 252919 and 257375 it has been shown that at higher pressures, which are at the limit of the fluid tension, which partially displaces water from the cells so that this results in an enlargement of the harmful space; part of the tensioned conveyor is on brought over from the pressure side to the suction side in this way and prevents that here Suction until it is expanded to suction tension.
Um diese schädliche Wirkung zu beseitigen, werden nach dem Erfindungsgedanken an dem Steuerkörper ein oder mehrere Uberströmkanäle angebracht, durch welche das in dem schädlichen Raum enthaltene Druckmittel hinüber in die bereits abgeschlossenen, jedoch noch möglichst ungespanntes Druckmittel enthaltenden Zellen der Saugseite expandieren kann, in welchen hierdurch eine Vorkompression eintritt.In order to eliminate this harmful effect, according to the inventive idea on the Control body attached one or more overflow channels through which the in the harmful space contained pressure medium over into the already locked, however Expand the cells of the suction side that contain as little pressure medium as possible can, in which a precompression occurs as a result.
Fig. ι ist eine schematische Darstellung des Erfindungsgegenstandes.Fig. Ι is a schematic representation of the subject of the invention.
Läuft das Zellenrad ζ in der Richtung des Pfeiles χ um, so wird bei b angesaugt, bei a herausgedrückt. c ist der Überströmkanal, durch welchen das Expandieren des Inhaltes der schädlichen Räume eintritt.If the cellular wheel ζ rotates in the direction of the arrow χ , it is sucked in at b and pushed out at a . c is the overflow channel through which the expansion of the contents of the harmful spaces occurs.
