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).

Figure imgaf001
A Venturi mixing nozzle has a cross tube (3) in a fluid inlet section (2). An opening (Oe) provided in the cross tube (3) lies in a flow area of a first fluid. Through the opening (Oe) a portion of the fluid flowing through the Venturi mixing nozzle is passed into the cross tube (3), whereby in the cross tube (3) a back pressure is generated. This compensates for a negative pressure created by the flow of a fluid flowing through the Venturi mixing nozzle such that a pressure at a first pressure opening (P1) corresponds at least to zero. As a result, a pressure difference (P2-P1) between a second pressure opening provided at the narrowest point of the Venturi mixing nozzle and the first pressure opening corresponds at least to the negative pressure at the second pressure opening (P2).
