Description

Ventillose Kolbenpumpe für Flüssigkeiten von hoher Viskosität. Gegenstand der Erfindung ist eine ventillose Kolbenpumpe, insbesondere zur Förderung von Viskose, bei der die Kolben in einer drehbaren Zylindertrommel durch eine Schrägscheibe achsial bewegt werden. Es ist hierbei bekannt, die Schrägscheibe zu verstellen. indem sie mit ihrer kugeligen Außenfläche in dem innen ebenfalls kugelig ausgebildeten Gehäuse angeordnet ist. Hierdurch entsteht eine erheblich lange und dadurch schwere Bauart, die nicht ohne weiteres die Einstellbarkeit sofort erkennen läßt. Erfindungsgemäß wixd nun nicht das Gehäuse rings, sondern nur teilweise um die Schrägscheibe geführt, so daß letztere das Abschlußmittel bildet und ihre Einstellung ohne weiteres erkannt werden kann. Außerdem wird auch die Bauart der Pumpe kurz und leicht.Valveless piston pump for liquids of high viscosity. object the invention is a valveless piston pump, especially for pumping viscose, in which the pistons are axially in a rotatable cylinder drum through a swash plate be moved. It is known here to adjust the swash plate. by with their spherical outer surface in the housing, which is also spherical on the inside is arranged. This creates a considerably long and therefore heavy construction, which does not immediately reveal the adjustability. According to the invention wixd now not the case around, but only partially guided around the swash plate, so that the latter forms the closing means and recognizes its attitude without further ado can be. In addition, the design of the pump becomes short and light.

Auf der Zeichnung ist im Schnitt ein Ausführungsbeispiel des Oberteiles einer Pumpe nach der Erfindung dargestellt.The drawing shows an exemplary embodiment of the upper part in section shown a pump according to the invention.

In dem Gehäuse i befindet sich die Trommel 2 mit den Kolben 12. Der Mittelstempel i 8 der Pumpe trägt über einer kugelig aus--edrehten Stirnfläche einen Kugelkopf des Mittelzapfens 28 der Steuereinrichtung für die Achsialbewegung der Kolben 12. Die Kugelköpfe 28 der Kolben liegen in Spurplatten 26, 27, und diese befinden sich zwischen den durch den Mittelzapfen 28 zusammengehaltenen schrägen Führungsscheiben 29 und 30 innerhalb des Deckels 33. Dieser Deckel ist außen bei 4.o kugelig abgedreht und liegt in einer Kugelpfanne 41 in der Stirn des Gehäuses i. In der KugelaLisdrehung -to liegt eine " Ringnut 4.2, und in diese greifen die Köpfe von Stellschrauben 34 ein, die in den Pumpenkörper i eingeschraubt sind. Durch die Verstellung dieser Schrauben 34 ist die Lage des Deckels 33 und damit die Lage des Steuerteiles für die Kolben 12 veränderbar, indem der Neigungswinkel gegenüber der Achse des Stempels 18 verändert wird.The drum 2 with the piston 12 is located in the housing i. The central piston i 8 of the pump carries a spherical head of the center pin 28 of the control device for the axial movement of the piston 12 via a spherical end face Track plates 26, 27, and these are located between the inclined guide disks 29 and 30 held together by the central pin 28 within the cover 33. This cover is turned off spherically on the outside at 4.o and is located in a ball socket 41 in the front of the housing i. In the KugelaLis turn -to there is an "annular groove 4.2, and the heads of adjusting screws 34, which are screwed into the pump body i, engage in this. By adjusting these screws 34, the position of the cover 33 and thus the position of the control part for the Piston 12 can be changed by changing the angle of inclination with respect to the axis of the punch 18.

Der Mittelpunkt 11i1 der Kugelflächen 4o und 41 liegt, in der Achse des Zapfens 28 und in der Ebene, in der sich die Mittelpunkte sämtlicher Köpfe 25 der Kolben i2 befinden. Bei einer Verstellung dreht sich das Deckelgehäuse um eine durch den Punkt M senkrecht zur Zeichenebene gehende Achse. Auf dem Durchmesser senkrecht zu dieser Achse sitzen die Verschlußschrauben 3q.. Sie halten das Deckelgehäuse ohne Spiel fest, sichern sich gegenseitig und verhindern jede Lockerung. Die Kugelflächen 40, 41 dichten das Deckelgehäuse 33 bei jeder Stellung wirksam ab, ohne daß ein besonderer Deckel mit Stopfbuchsen u. digl. erforderlich ist.The center 11i1 of the spherical surfaces 4o and 41 lies in the axis of the pin 28 and in the plane in which the centers of all the heads 25 the piston i2 are located. When adjusted, the cover housing rotates one through the point M perpendicular to the plane of the drawing axis. On the diameter The locking screws 3q .. are located perpendicular to this axis. They hold the cover housing tight without play, secure each other and prevent any loosening. The spherical surfaces 40, 41 seal the cover housing 33 effectively in every position without a special cover with glands and digl. is required.
