Abstract (en)

A device configured to produce a gas-liquid mixture for firefighting purposes is disclosed. The device comprises a mixing container configured to receive a liquid medium and a pressurized gaseous medium, wherein the mixing container has an outlet for the gas-liquid mixture and a mixing pipe arranged within the mixing container and configured to guide the gas-liquid mixture towards the container outlet. The mixing pipe comprises a wall having a mixing passage configured to introduce the gaseous medium from an outside of the mixing pipe into the liquid medium, when same is guided within the mixing pipe towards the container outlet. The mixing passage has a first cross-sectional area and a portion of the mixing pipe downstream of the mixing passage or of a discharge line downstream of the mixing pipe has a second cross-sectional area. The ratio between the first cross-sectional area and the second cross-sectional area is between 1:4 and 1:25.
