Abstract

The sealing of cartridges, in which a liquid is stored and from which the liquid can be conveyed in each case by means of a piston which is axially movable in the cartridge, is all the more problematic, the more highly viscous said liquid is because considerable internal pressures then occur during delivery. By means of pressure pieces (3) which are appropriately provided on the piston and are charged with the compression force (F) providing the delivery, the invention ensures that the pressing-on force of the piston against the wall of the cartridge increases with an increasing internal pressure. <IMAGE>

Description

Dichtungs- und Klebemittel werden häufig in Kartuschen geliefert und mit Hilfe von Dosier­ pistolen mit mechanischer- oder pneumatischer Betätigung verarbeitet.Sealants and adhesives are commonly used in Cartridges supplied and with the help of dosing pistols with mechanical or pneumatic Operation processed.

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.In order to achieve a better seal between the piston and the cartridge with increasing internal pressure, the circumference of the elastic piston crown 1 is increased by the action of the spreading lips 2 , brought about by mechanical pressure on the pressure plate 3 shown in broken lines. The spreading lips 2 are designed as a conical circumferential ring with a plurality of incisions 5 .

Damit der Kolbenanlauf auch nach längerer Lagerzeit gewährleistet ist, besitzt der Kolben mehrere radial verlaufende Kammern 4 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 up even after a long storage period, the piston has several radial chambers 4 for receiving a suitable lubricant. The shaft of the piston has three successive flexible lips 6 so that the piston is adequately sealed. A plurality of ribs 7 are attached to the inner wall of the piston to reinforce the shaft. To facilitate the piston insertion, a slope 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 crown 1 is designed in the form of a carrot so that the air present can escape when the piston is inserted and an improved residual emptying is provided.

Fig. 1 zeigt einen Querschnitt durch den Kolben. Fig. 1 shows a cross section through the piston.

Fig. 2 zeigt eine Innenansicht des Kolbens; man erkennt darin die Anordnung der Rippen 7. Fig. 2 shows an inside view of the piston; the arrangement of the ribs 7 can be seen therein.
