Abstract

Die Erfindung betrifft eine Ventilvorrichtung (114, 119, 123) für eine Fluidbereitstellungseinheit (100), wobei die Ventilvorrichtung (100) einen Fluidbehälter (114) aufweist. Des Weiteren umfasst die Ventilvorrichtung (114, 119, 123) eine Verschlusseinheit (119) mit einer Verschlussmembran (120) und einer Dichtstelle (121) zwischen der Verschlussmembran (120) und dem Fluidbehälter (114), wobei die Dichtstelle (121) den Fluidbehälter (114) fluiddicht verschließt. Ferner ist die Ventilvorrichtung (114, 119, 123) mit einem Mittel (123) zum Ausüben eines Fluiddrucks auf zumindest eine Seite der Verschlussmembran (120) versehen, wobei die Verschlussmembran (120) und/oder die Dichtstelle (121) ausgebildet ist, um durch den Fluiddruck zumindest teilweise beschädigt zu werden.

The invention relates to a valve device (114, 119, 123) for a fluid supply unit (100), wherein the valve device (100) has a fluid container (114). Furthermore, the valve device (114, 119, 123) comprises a closure unit (119) with a closure membrane (120) and a sealing point (121) between the closure membrane (120) and the fluid container (114), wherein the sealing point (121) the fluid container (114) closes fluid-tight. Furthermore, the valve device (114, 119, 123) is provided with a means (123) for exerting a fluid pressure on at least one side of the closure membrane (120), wherein the closure membrane (120) and / or the sealing point (121) is designed to at least partially damaged by the fluid pressure.
