  Einrichtung zum Gleichhalten der   Drehzahl von Wasserrädern   od. dgl.   bei Anordnung   eines vom Oberwassergerinne abzweigenden Nebengerinnes mit Absperrorgan. 



   Gegenstand vorliegender Erfindung ist eine Einrichtung zum Gleichhalten der Drehzahl von Wasserrädern. 



   Die Zeichnung zeigt ein   Ausführungsbeispiel   des Eiindungsgegenstandes, u. zw. stellt Fig. 1 einen Aufriss im Schnitt, Fig. 2 eine Draufsicht dar. 



   Mit 1 ist das Wasserrad bezeichnet, dessen Drehzahl durch das Regelverfahren tunlichst konstant gehalten werden soll ; 2 ist das Oberwasseigeiinne, das unmittelbar vor dem Wasseraustritt eine Kammer 3 aufweist, die durch eine Querwand 4 in zwei Teilkammern Ja und 3b geteilt wild. Die   Teilkammer 3a   ist oben offen, so dass sie mit dem Oberwassergerinne in Verbindung steht ; die   Teilkammer. 3b kann   durch eine   Dlosselklappe 5   von der Teilkammer 3a abgesperrt oder entsprechend der Stellung dieser Klappe mit ihr verbunden werden. Im letzteren Falle tritt das die   Kammer 3 passierende   Wasser durch das Gerinne 6 aus. 



   Auf der Welle 7 des Wassenades sitzt die Riemscheibe   8,   welche auf die Scheibe 9 der Regler- 
 EMI1.1 
 über das Geiinne 6 ab. Dieses Gerinne ist gemäss der Fig. 1 des gezeichneten   Ausführungsbeispieles   so angeordnet,   dass das au@@liessende Wasser auf das Rad 1 bremsend wirkt,   mithin die drehzahlmindernde Wirkung des Regelvorganges unterstützt. Diese doppelt regulierende Einwirkung der Drosselklappe durch   Veningern   der   wirksamen Wassermenge im Ge@inne   2 und gleichzeitiges Verwenden des überschüssigen Wassers als Bremswasser hat zur Folge, dass die Verstellwege der Reglermuffe und mithin die Abmessungen des Reglers bedeutend   herabgemindert   werden können. 



   Es ist klar, dass man an Stelle des gezeichneten Fliehkraftreglers R auch jede andere geeignete Reglergattung verwenden kann. Auch kann man statt der Drosselklappe irgend ein anderes \bsperrorgan dem Einfluss des Reglers unterwerfen.

  Device for keeping the speed of water wheels constant or the like when arranging a secondary channel branching off from the upper channel with a shut-off device.



   The present invention relates to a device for maintaining the speed of water wheels constant.



   The drawing shows an embodiment of the binding object, u. Between Fig. 1 is a sectional elevation, and Fig. 2 is a plan view.



   1 with the water wheel is referred to, the speed of which should be kept constant as far as possible by the control process; 2 is the Oberwasseigeiinne, which has a chamber 3 immediately before the water outlet, which is divided by a transverse wall 4 into two sub-chambers Ja and 3b. The sub-chamber 3a is open at the top so that it is in communication with the upper water channel; the sub-chamber. 3b can be shut off from the sub-chamber 3a by a Dlossel flap 5 or connected to it according to the position of this flap. In the latter case, the water passing through the chamber 3 exits through the channel 6.



   On the shaft 7 of the water wheel sits the pulley 8, which on the pulley 9 of the regulator
 EMI1.1
 via Geiinne 6. According to FIG. 1 of the illustrated embodiment, this channel is arranged in such a way that the water flowing out has a braking effect on the wheel 1, and consequently supports the speed-reducing effect of the control process. This double regulating effect of the throttle valve by reducing the effective amount of water in Ge @ inne 2 and at the same time using the excess water as brake water has the consequence that the adjustment paths of the regulator sleeve and thus the dimensions of the regulator can be significantly reduced.



   It is clear that any other suitable type of regulator can be used instead of the centrifugal regulator R shown. Instead of the throttle valve, any other blocking element can also be subjected to the influence of the controller.

PATENT-ANSPUCH : Eimichtung zum Gleichhalten der Drehzahl von Wasserrädein od. dgl. bei Anordnung eines vom Obeiwassergeiinne abzweigenden Nebengeiinnes mit Absperrorgan, dadurch gekennzeichnet, dass die als Absperrorgan eingebaute Drosselklappe (5) durch einen von der Wasseradwelle (7) angetriebenen Regler (R) beeinflusst wird und das bei Offenstellung derselben und dadurch verringerter Abflussmenge im Obergerinne durch das Nebengerinne austretende Wasser dem Wasserrrad als Bremswasser in einem der Drehrichtung desselben entgegenwirkenden Sinne zugeführt wird. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: A device for keeping the speed of waterwheels constant or the like with the arrangement of a secondary watercourse branching off from the upper watercourse with a shut-off device, characterized in that the throttle valve (5) built in as a shut-off device is influenced by a controller (R) driven by the waterwheel shaft (7) and that when the same is open and the flow rate in the upper channel is reduced, water exiting through the secondary channel is fed to the water wheel as braking water in a sense that counteracts the direction of rotation of the same. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
