Description

Pumpe einer Spritzeinrichtung für flüssiges Überzugsgut Membrankolbenpumpen, bei denen Kolben über ein Druckmedium eine Membran bewegen, um mit diesen Flüssigkeiten, wie Farben od. dgl., unter hohem Druck zu fördern und zu zerstäuben, sind bekannt. Hierbei treibt eine Exzenterrolle den Kolben gegen die Kraft einer Rückstellfeder an.Pump of a spray device for liquid coating material Diaphragm piston pumps, in which pistons move a membrane over a pressure medium in order to communicate with these liquids, such as paints or the like, to be promoted and atomized under high pressure, are known. An eccentric roller drives the piston against the force of a return spring at.

Der Erfindung liegt die Aufgabe zugrunde, bei solchen Spritzeinrichtungen eine Förderrnengenregelung zu schaffen, die leicht auf die unterschiedliche Zerstäubungsfähigkeit und Abbindeeigenschaft der zu spritzenden überzugsstoffe einstellbar ist und eine möglichst geringe Membranbeanspruchung ergibt.The invention is based on the object of such spray devices to create a flow rate control that easily takes account of the different atomization capacity and the setting property of the coating materials to be sprayed is adjustable and one results in the lowest possible stress on the membrane.

Bei den bekannten Umlaufregelungen war nachteilig, daß sich die Umlaufkanäle mit der Zeit trotz Nachspülens durch Ablagerungen verengten und damit die Fördermenge unkontrolliert änderten.In the known circulation regulations it was disadvantageous that the circulation channels over time, despite rinsing, narrowed due to deposits and thus the delivery rate changed uncontrollably.

Erfindungsgemäß ist die Aufgabe dadurch gelöst, daß die Exzenterrolle für den Antrieb des Kolbens in bei Flüssigkeitsgetrieben an sich bekannter Weise auf einer gegenüber dem Kolben axial einstellbaren Antriebswelle unter einem spitzen Winkel zu deren Achse gelagert ist.According to the invention the object is achieved in that the eccentric roller for driving the piston in a manner known per se in fluid transmissions on a drive shaft axially adjustable with respect to the piston under a pointed Angle is mounted to the axis.

Bei dieser erfindungsgemäßen Anordnung ergibt sich weiterhin der Vorteil, daß die Pumpe beim Fördem eines dicken überzugsgutes langsam laufen kann, dafür aber mit größerem Hub, so daß der dicke Stoff in den Pumpenraum ausreichend nachläuft.In this arrangement according to the invention there is also the advantage that the pump can run slowly when conveying a thick material to be coated, for this but with a larger stroke so that the thick material runs sufficiently into the pump chamber.

Schließlich ist auch der Forderung entsprochen, daß die stufenlose Hubregelung des Kolbens eine gleichmäßig zu- oder abnehmende Veränderung der Membranausschläge um eine Mittelstellung ergibt.Finally, the requirement that the stepless Stroke control of the piston a steadily increasing or decreasing change in the diaphragm deflections results in a middle position.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is shown in the drawing.

Ein Pumpenkolben 1 bewegt Öl oder ein anderes ähnliches Medium in einem anschließenden Raum 2 hin und her. Dadurch wird eine Membran 3 mitbewegt, die ihrerseits auf ein überzugsgut in einem darüberliegenden Raum 4 pumpend wirkt. Der Kolben 1 wird,mit Hilfe einer Feder 14 zurückgeholt und damit überzugsgut angesaugt.A pump piston 1 moves oil or another similar medium back and forth in an adjoining space 2. As a result, a membrane 3 is also moved, which in turn has a pumping effect on a material to be coated in a space 4 above. The piston 1 is withdrawn with the aid of a spring 14 and thus sucked in to be coated.

Bei 6 tritt das überzugsgut durch ein Saugventil ein, durchläuft den Raum 4 und gelangt durch ein Druckventil durch die Druckleitung 7 zur Zerstäuberdüse.At 6 , the material to be coated enters through a suction valve, passes through space 4 and passes through a pressure valve through pressure line 7 to the atomizer nozzle.

9 ist eine axial verschiebbare Antriebswelle und 13 eine unter einem spitzen Winkel auf der Welle aufgesetzte Exzenterrolle für den Antrieb des Kolbens 1. Für die axiale Verschiebung der Welle 9 ist ein Hebel 11 vorgesehen. Eine Antriebsstufenscheibe 10 ermöglicht verschiedene Drehzahlen. 9 is an axially displaceable drive shaft and 13 is an eccentric roller placed on the shaft at an acute angle for driving the piston 1. A lever 11 is provided for the axial displacement of the shaft 9. A drive stage pulley 10 enables different speeds.
