Abstract

A mixer comprises a hermetically sealed casing (1) with a cavity to be filled with a liquid, and an ejector (4) located within the casing (1). The ejector (4) includes a flow-through channel (6) serving as a mixing chamber for liquids, an inlet part (5) with at least one ejection aperture (14) which communicates the flow-through channel (6) with the cavity of the casing (1), and an outlet part (7) equipped with at least one aperture (15) for communicating the cavity of the mixing chamber with the cavity of the casing. A fire-extinguishing apparatus comprises a water supply system equipped with a mixer whose cavity is to be filled with a foaming agent. The invention allows the efficiency of mixing the liquids to be increased at different spatial positions of the mixer and at variations in the liquid pressure and flow velocities.
