Abstract (en)
[origin: EP2944355A1] A mixing assembly (116) for a firefighting device (102) is described. The mixing assembly comprises an inlet (118) configured to receive pressurized fire extinguishing fluid from a firefighting device pump (108) along a first flow axis (140). The assembly (116) further comprises a mixing section (124) with a differential pressure injector (146) configured to accelerate the fluid along a second flow axis (152) arranged at a first angle relative to the first flow axis and to inject a foaming agent in the fluid, thereby producing a mixture of the fluid and the foaming agent. An outlet (122) of the mixing assembly is configured to deliver the mixture along a third flow axis (164) that is arranged at a second angle relative to the second flow axis (152). Each of the first angle and the second angle lies approximately between 60 degrees and 120 degrees.
