Description

Pumpe für schleimige Flüssigkeiten. Mehrfach wirkende Pumpen für schleimige Flüssigkeiten mit in einer drehbaren Zylindertrommel geführten Kolben sind bekannt.Pump for slimy liquids. Multi-acting pumps for slimy ones Liquids with pistons guided in a rotatable cylinder drum are known.

Die vorliegende Erfindung betrifft eine in derartigen Pumpen vorgesehene Anordnung, um die Pumpenleistung innerhalb gewisser Grenzen zu regeln.The present invention relates to one provided in such pumps Arrangement to regulate the pump output within certain limits.

Diese Anordnung besteht aus einem zylindrischen Sektor, der in einer Aussparung des Gehäuses in achsialer Richtung verschiebbar ist; seine konkave Innenfläche legt sich an die Zvlindertrommel an und seine Außenfläche ist mit zwei Aussparungen versehen, von denen die eine dem Ansaugkanal gegenüber und die andere dem Druckkanal gegenüber zu liegen kommen. Diese beiden Aussparungen haben den Zweck, die Saug- bzw. Druckkammer zu bilden, mit welchen die entsprechenden Zylinderöffnungen der Zylindertrommel während der Rotation der letzteren in Verbindung kommen.This arrangement consists of a cylindrical sector in a Recess of the housing is displaceable in the axial direction; its concave inner surface rests against the cylinder drum and its outer surface has two recesses provided, one of which is opposite to the suction channel and the other to the pressure channel come to lie opposite. The purpose of these two recesses is to or to form pressure chamber with which the corresponding cylinder openings of the Cylinder drum come into connection during the rotation of the latter.

Je nach der bewirkten Verschiebung des Sektors werden die Aussparungen des Sektors mit den entsprechenden Ansaug- und Druckkanälen mehr oder weniger in Verbindung gebracht, wodurch die Leistung der Pumpe beliebig geregelt «-erden kann.Depending on the shifting of the sector, the recesses of the sector with the corresponding suction and pressure channels more or less in Connected, whereby the output of the pump can be regulated as required.

Der Erfindungsgegenstand ist in der Zeichnung in einer Ausführungsform dargestellt. Es zeigt: Abb. i einen mittleren Längsschnitt, Abb.2 eine Seitenansicht der Pumpe mit abgenommenem äußerem Pumpendeckel und Drehring, Abb.3 einen (Querschnitt nach Linie x-x der Abb. i.The subject of the invention is shown in the drawing in one embodiment shown. It shows: Fig. I a central longitudinal section, Fig. 2 a side view of the pump with the outer pump cover and rotating ring removed, Fig. 3 a (cross-section according to line x-x of Fig. i.

Abb. ¢ zeigt schematisch den verschiebbaren Sektor zur Regulierung der Pumpenleistung im Grundriß, mit Aussparungen, die zur Erleichterung des Verständnisses horizontal angeordnet sind.Fig. ¢ shows schematically the adjustable sector for regulation the pump performance in plan, with recesses to facilitate understanding are arranged horizontally.

In der Zeichnung bedeuten i und i' zwei fest miteinander verbundene, die Trommel der Pumpe bildende Zylinder. Die Zylindertrommel enthält die Bohrungen 2, in denen die Kolben 3 sich achsial bewegen. Die Zylindertrommel ist auf die Welle q. aufgekeilt, die durch Zahnrad 5 angetrieben wird. Die Kolben 3 liegen mit ihren beiden Enden gegen die Schrägscheiben 6 und 7, die mittels Dübeln 5' und 5" unverrückbar angeordnet sind.In the drawing i and i 'mean two firmly connected, cylinders forming the drum of the pump. The cylinder drum contains the bores 2, in which the pistons 3 move axially. The cylinder drum is on the shaft q. keyed, which is driven by gear 5. The pistons 3 are with their both ends against the swash plates 6 and 7, which are immovable by means of dowels 5 'and 5 " are arranged.

Die Zylindertrommel und die Schrägscheiben sind in einem Gehäuse 8 untergebracht, welches von den durch Schrauben i i und i i' festgehaltenen Deckeln 9 und io abgeschlossen wird, wobei die Deckel nach innen als schiefe Ebenen ausgebildet sind, gegen welche die Scheiben 6 und 7 anliegen.The cylinder drum and the swash plates are in a housing 8 housed, which of the lids held by screws i i and i i ' 9 and io is completed, the cover being designed inwardly as inclined planes against which the disks 6 and 7 rest.

Die einzelnen Zylinderräume kommen mit den Ausnehmungen 12 bzw. 13 des Gehäuses 8 bei der Drehung der Trommel in Verbindung, wobei die erstere mit dem Saugkanal 14 und die zweite mit dein Austrittskanal 15 verbunden ist.The individual cylinder spaces come with the recesses 12 and 13, respectively of the housing 8 in connection with the rotation of the drum, the former with the suction channel 14 and the second with the outlet channel 15 is connected.

Die Pumpe wird durch einen Windkessel 16 vervollständigt, der durch Kanal 17 mit der Ausbuchtung für den Austritt 13 des Gehäuses 8 in Verbindung steht und zur Regulierung des Gegendruckes der Pumpe dient.The pump is completed by an air chamber 16, which by Channel 17 is connected to the bulge for the outlet 13 of the housing 8 and is used to regulate the back pressure of the pump.

Zur Regulierung der Pumpenleistung ist in einer Aussparung 2o des Gehäuses 8 der längsverschiebbare Zylindersektor 18 angeordnet, der mit Aussparungen i 9 und 2o versehen ist. Diese Aussparungen haben den Zweck, die Saug- bzw. Druckkamrner zu bilden, mit denen während der Rotation der Zylindertrommel nach und nach die Saug- und Druckmündungen der verschiedenen Zylinder 2 in Verbindung gesetzt «erden; 22 ist eine in Sektor 18 vorgesehene Schraube, die denselben in der Aussparung 21 nach vorwärts und rückwärts zu verschieben bestimmt ist. 23 bezeichnet eine Schraube, um den Sektor 18 nach erfolgter Regulierung einzustellen. Durch die Verschiebung des Sektors 18 kommen die Aussparungen .i9 und 2o mehr oder weniger mit Saug- und Druckkanälen 14 und 15 in Verbindung, so daß die Menge der zu- und abfließenden Menge geändert werden kann.To regulate the pump output is in a recess 2o des Housing 8 of the longitudinally displaceable cylinder sector 18 arranged with recesses i 9 and 2o is provided. These recesses have the purpose of the suction or pressure chambers to form with which during the rotation of the cylinder drum gradually the The suction and pressure ports of the various cylinders 2 are connected to earth; 22 is a screw provided in sector 18, which screws into the recess 21 to move forward and backward is intended. 23 denotes a screw, to discontinue sector 18 after regulation has taken place. By the shift of the sector 18 come the recesses .i9 and 2o more or less with suction and Pressure channels 14 and 15 in connection, so that the amount of inflow and outflow Quantity can be changed.
