Abstract

Gegenstand der Erfindung ist eine Bypassventilanordnung für ein Hochdruckreinigungsgerät mit einer Förderpumpe (5) für Reinigungsflüssigkeit. Wesentlich für die erfindungsgemäße Bypassventilanordnung ist, daß zusätzlich zu der ersten Betätigungseinrichtung (20) für den Arbeitsdruck eine zweite, unabhängige Betätigungseinrichtung (30) für den Haltedruck vorgesehen ist, die eine Entlastung der Druckleitung (4) auf einen sehr niedrigen Haltedruck unabhängig vom Arbeitsdruck erlaubt.

The invention relates to a bypass valve arrangement for a high pressure cleaning device with a feed pump (5) for cleaning liquid. It is essential for the bypass valve arrangement according to the invention that, in addition to the first actuating device (20) for the working pressure, a second, independent actuating device (30) for the holding pressure is provided, which allows the pressure line (4) to be relieved to a very low holding pressure regardless of the working pressure .
