Patent-Anspruch:Patent claim: Vorrichtung zur Regelung der Fördermenge bei doppeltwirkenden Plungerpumpen, dadurch gekennzeichnet, daß der Kolben der Pumpe als Differentialkolben ausgebildet ist und zugleich ein durch ein Ventil (b) o. dgl. absperrbares Um- 3; lauf rohr (α) angeordnet ist, durch welches die vordere Pumpenseite mit dem hinteren Druckraum in eine derartige Verbindung gesetzt werden kann, daß bei geschlossenem Ventil die Pumpe als doppeltwirkende 4< Plungerpumpe und bei geöffnetem Ventil als Differentialpumpe arbeitet.Device for regulating the delivery rate in double-acting plunger pumps, characterized in that the piston of the pump is designed as a differential piston and at the same time a valve that can be shut off by a valve (b) or the like. running pipe (α) is arranged, through which the front side of the pump can be placed in such a connection with the rear pressure chamber that the pump works as a double-acting 4 <plunger pump when the valve is closed and as a differential pump when the valve is open.
