Abstract

Eine Venturi-Mischdüse weist in einem Fluideinlassabschnitt (2) ein Querrohr (3) auf. Eine in dem Querrohr (3) vorgesehene Öffnung (Oe) liegt in einem Strömungsbereich eines ersten Fluids. Durch die Öffnung (Oe) wird ein Anteil des durch die Venturi-Mischdüse strömenden Fluids in das Querrohr (3) geleitet, wodurch in dem Querrohr (3) ein Staudruck erzeugt wird. Dieser gleicht einen durch die Strömung eines durch die Venturi-Mischdüse strömenden Fluids entstehenden Unterdruck derart aus, dass ein Druck bei einer ersten Drucköffnung (P1) zumindest Null entspricht. Dadurch entspricht eine Druckdifferenz (P2 - P1) der zwischen einer an der engsten Stelle der Venturi-Mischdüse vorgesehen zweiten Drucköffnung und der ersten Drucköffnung zumindest dem Unterdruck bei der zweiten Drucköffnung (P2).
