Description

Dosier- und Mischpumpe für flüssige oder/und gasförmige Medien Die Erfindung betrifft eine Dosier- und Mischpumpe, insbesondere zum Dosieren und Mischen von flüssigen und gasförinigen Medien.Dosing and mixing pump for liquid and / or gaseous media The The invention relates to a metering and mixing pump, in particular for metering and mixing of liquid and gaseous media.

Es sind Dosierpumpen bekannt, mit denen jeweils ein Medium mit einer an der Pumpe angebrachten Fördermengenverstelleinrichtung dosiert bzw. gefördert werden kann. Der Erfindung liegt die Aufgabe zugrunde, eine einfach aufgebaute Pumpe zu schaffen, die sowohl die Dosierung als auch die Mischung von zwei Medien im flüssigen, im gasförmigen, oder im gasförmigen und flüssigen Zustand ermöglicht. Bei Anordnung von zwei oder mehr Kolben in Tandemausführung oder in Boxeranordnung lassen sich dann drei oder mehr Medien dosieren und mischen.There are known metering pumps, each with a medium with a The delivery rate adjustment device attached to the pump is metered or conveyed can be. The invention is based on the object of a simply constructed pump to create that both the dosing and the mixing of two media in the liquid, in the gaseous, or in the gaseous and liquid state. When ordered of two or more pistons in tandem or in a boxer arrangement then dose and mix three or more media.

Die Aufgabe löst die Erfindung dadurch, daß ein Pumpenzylinder einen Kolben enthält, in dem eine Nut und ein Verbindungskanal von der Nut zum Kolbenboden eingearbeitet sind, damit ein Medium von der Nut, die radial angeordnet ist, über den Kolbenboden gelangen kann.The object achieves the invention in that a pump cylinder has a Contains piston, in which a groove and a connecting channel from the groove to the piston head are incorporated to allow a medium from the groove, which is arranged radially, over can reach the piston crown.

Weitere Merkmale der Erfindung und die sich daraus ergebenden Vorteile sind der nachstehenden Beschreibung des in der Skizze dargestellten Ausführungsbeispiels zu entnehmen.Further features of the invention and the advantages resulting therefrom are the following description of the embodiment shown in the sketch refer to.

In der Skizze ist ein Zylinderinantel a gezeigt mit einem sich darin auf und ab bewegenden Kolben b, der eine Nut e besitzt, die 180" um den Kolben b verläuft und durch den Verbindungskanal d mit dem Raum über dem Kolben b in Verbindung steht. Seitlich am Zylindermantel a befindet sich in axialer Anordnung die Einlaßkammer f und genau gegenüberliegend die Auslaßkammer g. In der Einlaßkammer f ist ein verstellbarer Steuerkolben h vorhanden. Der Kolben b wird bei jeder Auf- und Abbewegung, während zwei Hüben, um 3600 axial verdreht. Die Hübe und die Drehung des Kolbens b werden in bekannter Weise mit geeigneten Maschinenelementen ausgeführt. Bei Abwärtsbewegung des Kolbens b und gleichzeitiger Drehung gleitet die Nut e des Kolbens b an der Einlaßkammer f vorbei und saugt zunächst das Medium I an. Bei weiterer Abwärtsbewegung und Drehung saugt der Kolben b das Medium II an, bis er den unteren Totpunkt erreicht hat. Nun hat dabei die Nut e des Kolbens b sich um 180' gedreht, so daß sie vor der Auslaßkaminer g steht und bei der Aufwärtsbewegung des Kolbens b das angesaugte Medium I und II durch den Verbindungskanal d in die Auslaßkammer ausstößt und fortleitet. Durch Auf- und Abwärtsbewegung des Steuerkolbens h in der Einlaßkammer f kann die Dosierung von Null bis maximal jedes der beiden Medien mit mathematischer Genauigkeit je nach Stellung des Steuerkolbens h in einem Hundertsatz von dem Verstellungswege bzw. der Verstellungslänge erfolgen. Bei dem Einlaß- und Auslaßvorgang werden beide Medien, besonders in Anbetracht der Drehung des Kolbens b innig miteinander gemischt.The sketch shows a cylinder jacket a with a piston b moving up and down in it, which has a groove e that runs 180 " around piston b and communicates with the space above piston b through connecting channel d . Laterally the inlet chamber f is axially arranged on the cylinder jacket a and exactly opposite the outlet chamber g. An adjustable control piston h is present in the inlet chamber f. The piston b is axially rotated by 3600 with every up and down movement during two strokes Strokes and the rotation of the piston b are carried out in a known manner with suitable machine elements. When the piston b moves downwards and rotates at the same time, the groove e of the piston b slides past the inlet chamber f and first sucks in the medium I. With further downwards movement and rotation sucks the piston b the medium II until it has reached the bottom dead center. Now the groove e of the piston b has rotated through 180 ' so that it is in front of the outlet chamber g is stationary and during the upward movement of the piston b the medium I and II which have been sucked in are ejected through the connecting channel d into the outlet chamber and conveyed away. By moving the control piston h up and down in the inlet chamber f, the dosage from zero to a maximum of each of the two media can be carried out with mathematical accuracy, depending on the position of the control piston h, in a hundredth of the adjustment path or the adjustment length. During the inlet and outlet process, both media are intimately mixed with one another , especially in view of the rotation of the piston b.
