Abstract

Die Erfindung betrifft eine Austragvorrichtung für ein fließfähiges Medium mit einer Pumpvorrichtung (40), die eine Pumpkammer (46) umfasst, die auf einer Seite durch einen längsbeweglichen Kolben (50) abgeschlossen ist.The invention relates to a discharge device for a flowable medium with a pump device (40), which comprises a pumping chamber (46) which is closed on one side by a longitudinally movable piston (50).

Erfindungsgemäß ist die Pumpkammer (46) kolbenseitig gegenüber einer Umgebungsatmosphäre außerhalb der Austragvorrichtung mittels einer gasundurchlässigen und zumindest teilweise flexiblen Membran (34) hermetisch abgedichtet ist, wobei die Membran (34) in ihrem Randbereich (36) fest mit einem Gehäuse (10) der Austragvorrichtung verbunden ist.According to the invention, the pumping chamber (46) is hermetically sealed on the piston side with respect to an ambient atmosphere outside the discharge device by means of a gas-impermeable and at least partially flexible membrane (34), the membrane (34) being fixed in its edge region (36) to a housing (10) of the discharge device connected is.

Verwendung für Austragvorrichtung mit hohen Anforderungen an die Abdichtung gegen den Eintritt von Verunreinigungen.
