Abstract: A spray nozzle for fire control produces a spray of gas and liquid having an oval transverse cross-section and comprises a mixing chamber having an oval transverse cross-section adapted to induce a toroidal mixing pattern in pressurised gas and liquid introduced to the mixing chamber (6) through a plurality of inlets (10, 8). In a preferred embodiment the mixing chamber (6) is toroidal. The spray nozzle may be used in fire control systems in vehicles or other confined spaces.
