Description

Kolben zur Förderung von niedrig- bis hochviskosen Flüssigkeiten aus KartuschenPistons for pumping low to high viscosity liquids from cartridges

Dichtungs- und Klebemittel werden häufig in Kartuschen geliefert und mit Hilfe von Dosierpistolen mit mechanischer- oder pneumatischer Betätigung verarbeitet.Sealants and adhesives are often supplied in cartridges and processed using dispensing guns with mechanical or pneumatic actuation.

Zur Erzielung einer besseren Abdichtung zwischen Kolben und Kartusche bei steigendem Innendruck erfolgt eine Umfangsvergrößerung des elastischen Kolbenbodens 1 durch die Wirkung der Spreizlippen 2, herbeigeführt durch ·■ mechanischen Druck auf die strichpunktiert gezeichnete Druckplatte 3· Die Spreizlippen 2 sind als konischer umlaufender Ring mit mehreren Einschnitten 5 ausgeführt.To achieve a better seal between the piston and cartridge when the internal pressure increases, the elastic piston base 1 is enlarged in circumference by the effect of the expanding lips 2, brought about by ·■ mechanical pressure on the pressure plate 3 shown in dash-dotted lines· The expanding lips 2 are designed as a conical circumferential ring with several incisions 5.

Damit der Kolbenanlauf auch nach längerer Lagerzeit gewährleistet ist, besitzt der Kolben mehrere radial verlaufende Kammern k zur Aufnahme eines geeigneten Schmiermittels. Damit eine ausreichende Dichtigkeit des Kolbens gesichert ist, besitzt der Schaft des Kolbens drei aufeinander folgende flexible Lippen 6. Zur Schaftverstärkung sind an der Kolbeninnenwand mehrere Rippen 7 angebracht. Zur Erleichterung der Kolbeneinführung ist an der oberen Mantelfläche eine Schräge 8 angebracht.To ensure that the piston starts running even after a long period of storage, the piston has several radial chambers k for holding a suitable lubricant. To ensure that the piston is sufficiently tight, the piston shaft has three flexible lips 6 in succession. To reinforce the shaft, several ribs 7 are attached to the inside wall of the piston. To make it easier to insert the piston, a bevel 8 is attached to the upper surface.

Der Kolbenboden 1 ist in Karlottenform ausgeführt, damit die vorhandene Luft beim Einführen des Kolbens entweichen kann und eine verbesserte Restentleerung gegeben ist.The piston bottom 1 is designed in a carrot shape so that the existing air can escape when the piston is inserted and an improved residual emptying is provided.

Die Figur 1 zeigt einen Querschnitt durch den Kolben« Figure 1 shows a cross section through the piston.

Die Figur 2 zeigt eine Innenansicht des Kolbens} man erkennt darin die Anordnung der Rippen 7. Figure 2 shows an interior view of the piston; one can see the arrangement of the ribs 7.
