KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Es ist in der Regel mit Schwierigkeiten verknüpft, grofse Pumpenmaschinen, sofern die Kolben unter dem vollen Drucke der Leitung stehen,- in Gang zu setzen. Ganz besonders schwierig ist es, wenn zum Antriebe elektrische Wechsel- oder Drehstrom-Motoren verwendet werden.As a rule it is connected with difficulties, in so far as the large pump machines are used The piston is under the full pressure of the line, - to start. Most notably It is difficult if electrical AC or three-phase motors are used for the drive will.

Durch die auf beiliegender Zeichnung dargestellte Erfindung werden die Maschinen in einfacher Weise anfänglich sicher in Gang gesetzt, so dafs sie später durch die eigentliche Betriebskraft weiter bewegt werden, ohne dafs sich irgend welche Schwierigkeiten geltend machen.Through the invention shown in the accompanying drawing, the machines are in is simply set in motion at the beginning, so that it can later be set in motion by the actual Operating power can be moved further without any difficulties arising do.

Die Erfindung besteht darin, dafs das in dem Druckrohr der Pumpe enthaltene oder besonders erzeugte Druckwasser durch eine Steuervorrichtung in den Kolbenraum (den Stiefel) der Pumpe, und zwar während der sonst in derselben herrschenden Saugperiode eingeführt und während der Druckperiode abgeleitet wird. Dadurch wird die Pumpenmaschine in einen Motor verwandelt.The invention consists in that the contained in the pressure pipe of the pump or in particular pressurized water generated by a control device in the piston chamber (boot) of the Pump, introduced during the suction period otherwise prevailing in the same and is derived during the printing period. This will turn the pump machine into transformed an engine.

in Fig. ι und 2 ist eine derartige Einrichtung beispielsweise gezeigt. Der Hebel A, der auch von Hand bedient werden kann, wird durch ein Gewicht oder dergl. P gegen eine auf der Pumpenwelle sitzende Excenterscheibe bewegt. Der Hebel A ist durch die Stange 5 mit dem Steuerschieber C verbunden, welcher so hin- und herbewegt wird, dafs in der vorbeschriebenen Weise das Druckwasser in den Pumpenstiefel D geleitet und nach der Bewegung des Kolbens wieder abgeleitet wird, wodurch die Bewegung des Pumpenkolbens und die der Maschine in der erforderlichen Weise hervorgebracht wird.In Fig. ι and 2 such a device is shown for example. The lever A, which can also be operated by hand, is moved by a weight or the like. P against an eccentric disk seated on the pump shaft. The lever A is connected by the rod 5 with the control valve C, which thus is reciprocated, that passed the water pressure in the pump boots D in the manner described above and is discharged again after the movement of the piston, whereby the movement of the pump piston and which is produced by the machine in the required manner.

Die Anordnung dieser Art der Inbetriebsetzung der Pumpe ist sowohl für einfache Plunger- und Differential-Plunger- als auch für zwei Plungerpumpen, sowie für drei oder mehr Plungerpumpen verwendbar.The arrangement of this type of start-up of the pump is easy for both Plunger and differential plunger pumps as well as for two plunger pumps, as well as for three or more Plunger pumps can be used.

In die Druckzuleitung a, sowie in die Verbindungsleitung b und in die Abwasserleitung c der Steuerung C sind Absperrungen a1 bl cl eingeschaltet, so dafs die Steuerung jederzeit aufser Thätigkeit gesetzt werden kann; ebenso kann durch Zurücklegen des Hebels A die Bewegung des Steuergestänges aufser Thätigkeit gebracht werden. Shut-offs a 1 b l c l are switched on in the pressure supply line a, as well as in the connecting line b and in the waste water line c of the control system C , so that the control system can be switched on at any time; in the same way, the movement of the control rod can be stopped by moving the lever A back.
