Description

Kolbenmischpumpe Zusatz zum Patent: 1 196965 Die Erfindung betrifft eine Kolbemnischpumpe nach Patent 1 196965, bei der ein umlaufender, auf seinem Mantel mit einer Längsnut versehener, in einem Zylinder geführter Hubkolben vorhanden ist, dessen Nut Schlitzkammern, die den Kolben ringförmig umgeben, mit dem Kolbenhubraum in Verbindung zu bringen vermag, wobei die beim Ansaugen wirksame Schlitzkammer durch eine in Umfangsrichtung einstellbare Nase in zwei Teile unterteilt ist. Wird eine derartige Kolbenmischpumpe als Zweizylindermischpumpe ausgeführt, so ermöglicht dies vier Komponenten, a, b, c, d, in zwei Gruppen a, b und c, d genau und stufenlos regelbar zu mischen, und zwar so, daß bei den Komponenten a und b (bzw. c und d) die Komponente a (bzw. c) von Null bis zu einem Maximum und von einem Maximum von Null beliebig mit der Komponente b (bzw. d) gemischt werden kann, wobei jedoch die Summen von a + b und von c + d jeweils konstant bleiben.Piston mixing pump Addendum to patent: 1 196965 The invention relates to a piston mixing pump according to patent 1 196965, in which a rotating, on his Shell provided with a longitudinal groove, reciprocating piston guided in a cylinder is, the groove of which is slit chambers, which surround the piston in an annular manner, with the piston displacement able to bring in connection, with the slit chamber effective during suction is divided into two parts by a circumferentially adjustable nose. Will such a piston mixing pump designed as a two-cylinder mixing pump allows this four components, a, b, c, d, in two groups a, b and c, d precisely and continuously to be mixed controllably, in such a way that for components a and b (or c and d) the component a (or c) from zero to a maximum and from a maximum of Zero can be mixed with component b (or d) as desired, but with the Sums of a + b and of c + d each remain constant.

Mit der als Doppelpumpe ausgeführten Mischpumpe nach dem Hauptpatent ist es also nicht möglich, die Summe der Komponenten c und d von Null bis zu einem Maximum zu verändern. Bestimmte Betriebe (z. B. Farbstoffchemie) legen besonderen Wert darauf, in kontinuierlicher Weise zu einer konstanten Menge einer Mischung aus zwei variablen Komponenten eine von Null bis zu einem Maximum variable Menge eines Stoffes oder eines Zweistoff-Gemenges beizufügen. With the mixing pump designed as a double pump according to the main patent so it is not possible to sum the components c and d from zero to one To change maximum. Certain establishments (e.g. dye chemistry) set special It is important to keep a constant amount of a mixture in a continuous manner from two variable components an amount variable from zero to a maximum of a substance or a mixture of two substances.

Der Erfindung liegt die Aufgabe zugrunde, diese Möglichkeit zu schaffen. Die Lösung besteht darin, daß bei Doppelanordnung der Mischpumpe nach dem Hauptpatent einem der Hubkolben in an sich bekannter Weise ein Hilfskolben zugeordnet ist, der vom Hubkolben vom unteren zum oberen Totpunkt entgegen einer Rückführkraft mitgenommen wird und dessen Hub, z. B. mittels einer Stellmutter von außen einstellbar ist. The invention is based on the object of creating this possibility. The solution is that with a double arrangement of the mixing pump according to the main patent an auxiliary piston is assigned to one of the reciprocating pistons in a manner known per se, which taken by the reciprocating piston from bottom to top dead center against a return force is and its hub, z. B. is adjustable from the outside by means of an adjusting nut.

Es gilt somit folgendes: a: b = variabel; = a + b = konstant; c: d = variabel; = c + d = variabel von Null bis zu einem Maximalwert. The following applies: a: b = variable; = a + b = constant; c: d = variable; = c + d = variable from zero to a maximum value.

Die Zeichnung bringt den Aufbau eines Ausführungsbeispiels der Erfindung schematisch im Längsschnitt. The drawing shows the structure of an embodiment of the invention schematically in longitudinal section.

Der untere Teil der Zeichnung gibt den Aufbau der Einzylindermischpumpe nach dem Hauptpatent wieder. Der obere Teil veranschaulicht die Weiter- entwicklung der zweiten Pumpe bei der Doppelanordnung. The lower part of the drawing shows the structure of the single-cylinder mixing pump after the main patent again. The upper part illustrates the further development the second pump in the double arrangement.

In dem oberen Zylinderl bewegt sich der mit Axialschlitz 2 versehene Kolben 3. Im gleichen Zylinderl läuft auf dem Kolben 3 aufsitzend und über die Druckfeder 4 mit diesem Kolben 3 zum Gleichlauf gezwungen, ein Hilfskolben 5. Solange der Hilfskolben 5 und der Kolben 3 gleich und mit gleichem Hub laufen, ist die von der Pumpe geförderte Menge Null, da das wirksame Volumen 7 von dem Raum zwischen dem Kolben 3 und dem Hilfskolben 5 gebildet wird. The one provided with the axial slot 2 moves in the upper cylinder Piston 3. In the same cylinder, it runs sitting on piston 3 and over the compression spring 4 forced to synchronize with this piston 3, an auxiliary piston 5. As long as the auxiliary piston 5 and the piston 3 run the same and with the same stroke, is the one delivered by the pump Quantity zero, since the effective volume 7 of the space between the piston 3 and the Auxiliary piston 5 is formed.

Wird der Hilfskolben 5 mittels des Stellgewindes 8 und der Stellmutter 9 z. B. so fixiert, daß er im oberen Totpunkt des Kolbens 3 stehen bleibt, so wird das Maximum der Pumpe gefördert. If the auxiliary piston 5 by means of the adjusting thread 8 and the adjusting nut 9 z. B. fixed so that it remains in the top dead center of the piston 3, so will the maximum of the pump promoted.

Jede Zwischenstellung ist möglich. Any intermediate position is possible.
