KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Der Erfindungsgegenstand bezieht sich auf eine Kolbensteuerung für Pumpen mit umlaufendem, in der Kolbentrommel absatzweise drehbarem Kolbenkreuz.The subject matter of the invention relates to a piston control for pumps with rotating pumps in the piston drum rotatable piston cross.
In der Zeichnung ist die Erfindung durch zwei Figuren in verschiedenen Arbeitsstellungen der Steuerung dargestellt.In the drawing, the invention is represented by two figures in different working positions shown on the control.
Wird nach Fig. ι die Trommel α mittels der Achse b in der Pfeilrichtung angetrieben,If according to Fig. Ι the drum α is driven by means of the axis b in the direction of the arrow,
ίο so saugt der in der Kammer c dicht schließende Kolben d die Flüssigkeit aus dem Saugrohr β und drückt sie in das Druckrohr f. Hierbei stützt sich der Kolben d mit dem unteren Arm des Kolbenkreuzes gegen die in der Kolbentrommel befestigte drehbare, mit einem Ausschnitt versehene Walze i. Die Umlegung des Kolbens d zum Vorbeigang am Widerlager g geschieht in der Weise, daß ein • mit der Walze verbundener Arm h mit Nase η gegen einen festen Zapfen I anschlägt, wodurch die Walze i derart gedreht wird, daß sie in die Stellung nach Fig. 2 kommt. ίο the piston d, which closes tightly in the chamber c, sucks the liquid out of the suction tube β and presses it into the pressure tube f. Here, the piston d rests with the lower arm of the piston cross against the rotatable and cut-out which is fastened in the piston drum Roller i. The turning of the piston d to pass the abutment g takes place in such a way that an arm h connected to the roller strikes with nose η against a fixed pin I , whereby the roller i is rotated in such a way that it moves into the position according to FIG. 2 is coming.
In dieser Stellung wird der untere Arm des Kolbenkreuzes frei, und der Arbeitskolben d wird von dem Flüssigkeitsdruck um 90 ° gedreht. Durch diese Drehung wird jedoch gleichzeitig die Walze i wieder dadurch zurückgedreht, daß der untere Arm des Kolbenkreuzes an der Wandung des Walzenausschnittes entlang gleitet. Es kann sich also der frühere Arbeitskolben d auf die Walze auflegen, so daß er nunmehr als Stütze für den auf der anderen Seite des Widerlagers in den Arbeitsraum hineingedrehten neuen Arbeitskolben dient.In this position, the lower arm of the piston cross is free, and the working piston d is rotated by 90 ° by the fluid pressure. As a result of this rotation, however, the roller i is simultaneously rotated back again in that the lower arm of the piston cross slides along the wall of the roller cutout. The former working piston d can therefore rest on the roller, so that it now serves as a support for the new working piston rotated into the working space on the other side of the abutment.
